Names matter

These body parts have a proper name that most people don’t know about

Would you be able to confidently point at your pinna if asked? Or could you say how many canthi a person has? Each part of our body has a specific name—sometimes more than one—but we don’t always use them or even know them, especially if a popular version exists. The big toe, the bit of flesh between the index and the thumb, the space between the brows, all these have a proper name that is rarely used. Let’s discover the proper way to refer to some parts of our body.

We typically refer to the space beneath the shoulder as the armpit or underarm, but the technical name for it is axilla. The name comes from a diminutive form of the Latin ala, meaning ‘wing’ or ‘upper arm’, which would make the armpit the ‘little wing’.

This ‘little wing’ serves as a passageway for important nerves, blood vessels, and lymph nodes that supply our upper arm, making it a vulnerable spot but also very sensitive and ticklish, as our body instinctively tries to protect the area.

There is a reason why we call the top of the upper lip the "Cupid’s bow". The philtrum, or the vertical groove that goes from the button of the nose to the lip, is named after the Greek word phíltron, meaning ‘love spell or charm’.

This area was once considered to possess a special beauty, and the philtrum was the path where Cupid's love arrows would land. Anatomically, its role in humans is debated; while some researchers consider it a leftover from our evolutionary past with little remaining function, others have proposed it may still play minor roles, such as in upper lip mobility. In other mammals, it's more clearly tied to the sense of smell, helping direct scent molecules toward specialized olfactory organs.

How do you refer to the space between your eyebrows? While most of us say "the space between the eyebrows", the correct name is glabella, a Latin word meaning ‘smooth’ or ‘hairless’.

The origin of the name is quite straightforward: while many mammals have "eyebrows", their brow bones are protruding and are often completely covered in fur. In humans, the brow bone is flat and smooth, and the area between the brows is typically hairless.

No one really knows how the bit of skin between the thumb and the index finger came to be called purlicue. Some say that it is a combination of the Scots pirlie (‘curl’) and the French cue (‘tail’)

This term was first used for squiggly writing or for the decorative flourish at the end of a word, but etymologists still can’t explain how it came to be used for the curve of the hand.

The term ‘ear’ encompasses both the outer and inner parts of the ear, but each component has its own name. Pinna, meaning ‘wing’, is the proper name of the visible ear, sometimes also called auricle, including both the cartilaginous and the fleshy part.

Although the inner ear is mainly responsible for converting sound into electrical signals and sending them to our brain, the pinna acts like a funnel that amplifies the sound vibrations and directs them into the ear canal.

We have specific names for every finger, but what about the toes? The names for the toes mirror those of the fingers (index, middle, ring, pinky), except the big toe, which is called the hallux, after the Medieval Latin hallex, meaning ‘great toe’.

However, this scientific name still has a connection with the thumb, as linguists believe that the spelling of hallux was influenced by the Latin word pollex, meaning ‘thumb’.

Several parts of the human body have a frenum (or frenulum), or a small band of tissue that restricts a mobile organ, such as the one connecting the underside of the tongue with the mouth.

This name comes from the Latin frenum, meaning ‘rein’ or ‘bridle’, equating the way tissue anchors and restricts the movement of the organ to how a rein directs and controls an animal.

If you thought that the corners of our eyes didn’t have a proper name, you are in for a surprise. The spot where the upper and lower lids meet —both inner and outer— is called canthus (canthi in plural), after the Greek kanthós, meaning ‘angle’ or ‘corner’.

Over the inner canthus, some people have a skin fold, called epicanthus (‘above the canthus’) or epicanthic fold. The shape of this fold —influenced by genetics, age, or medical conditions— often results in the upper lid being partially or completely hidden when the eye is open.

We often call it the cheekbone, but the proper name for it is zygoma, meaning ‘yoke’ or ‘bolt’ in Greek. Why was this name chosen? This bone acts like a bridge or yoke that connects the facial bones with the skull.

The scientific name for this bone is quite old, dating back to the 2nd century and to famous physicians such as Galen, who were the first to compare the cheekbone with a yoke. However, the term entered the English language only in the late 17th century.

Our nose has two nares or nostrils, separated by a strip of skin. Have you ever wondered if that small piece had a name? Well, it does, and it’s called columella, a diminutive form of the Latin columna (‘column’ or ‘pillar '), reflecting how the strip of nasal tissue stands like a column between the nostrils.

This word entered English in the 16th century, but it wasn’t only used to describe the human nose. Instead, it was adopted by many scientific fields to describe different structures that resembled a column.

Is there a clear distinction between the chin and the point of the chin? We often call the point of the chin just ‘chin’, but it's actually called the gnathion, derived from the Greek gnathos (‘jaw’ or ‘mouth’).

Gnathion is the diminutive form of gnathos, and could be translated as ‘little chin’. While anatomically, ‘chin’ describes the entire forward part of the lower jaw, the term gnathion refers to the pointiest part of it.

Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
