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.

Hospital secrets

What is a "Code Gray" and what you should know if you hear it at the E.R.

A trip to the emergency room can be stressful enough without hearing doctors and nurses speak a language that sounds like a secret code. One minute, someone is asking for medication "STAT," the next there’s a "Code Gray," and another patient is suddenly "NPO." What do those words really mean? Some are official medical terms, others are insider slang, but they all help hospital staff communicate quickly when every second counts. Here are 10 of those codes explained.

The E.R. can be hectic and unpredictable. Most patients are frightened or uncomfortable, but now and then someone becomes aggressive because of pain, confusion, mental illness, or the effects of alcohol or other substances. That’s when you can hear "Code Gray" announced over the speakers.

The code is used to summon security officers to help manage a violent or combative situation. While color codes vary from one hospital to another, Code Gray commonly signals that staff needs extra assistance to protect patients, visitors, and healthcare workers. Even if you know it now, most people in the waiting room never know what happened, and that’s exactly the point.

You have a scheduled surgery, you’re in your bed waiting to be taken to the surgery room, and you ask for a cup of coffee to make the wait lighter. The nurse will probably tell you you’re an NPO. You may think it’s serious, but it’s simply a procedure.

"NPO" is an abbreviation that comes from the Latin phrase Nil Per Os, which means "nothing by mouth." It tells patients they cannot eat, drink, or sometimes even take medication until doctors say it’s safe. The rule is most common before surgery or certain medical tests, when food or liquids could increase the risk of complications or alter the results. It may be frustrating, but it’s an important part of keeping patients safe.

You’ve probably been through the experience of visiting an emergency room, either to get checked or to visit a loved one. In that part of the hospital where everyone is rushing to save lives, you’ve probably heard a doctor asking for the R.C.P. cart or medication "STAT!" It sounds urgent, and that's because it is.

The expression comes from the Latin statim, which means "immediately" or "without delay." Hospitals have used Latin medical terms for centuries, but STAT is one of the few that remains part of everyday conversation. When a doctor says it, the request jumps to the top of the priority list. It doesn’t always refer to a life-or-death situation, but it does mean the medical team needs something done as quickly as possible.

Newborns are always a reason to celebrate at the hospital. Parents usually rest happily next to their child as they receive congratulations from close relatives. However, the hospital is always prepared to handle extremely rare emergencies under "code pink."

If you hear a "Code Pink," it usually means a baby or young child is suspected of being abducted from the hospital. Within seconds, security officers respond, exits may be monitored or blocked, and staff begins following carefully rehearsed procedures. Although different hospitals sometimes use different color codes, Code Pink has become widely recognized across North America as one of the most serious alerts a hospital can issue.

If you’ve ever spent a few days in the hospital, you’ve probably noticed that some patients are walking up and down the halls, while others need help just getting out of bed. When a nurse refers to someone as a "walkie-talkie," it’s actually good news.

This informal expression refers to patients who can walk on their own, use the bathroom without assistance, and handle most basic tasks independently. It’s not an official medical term, of course, but it’s commonly used among healthcare workers because it quickly tells the next shift that the patient requires less hands-on care than many others.

As nurses change shifts, you’ll often hear them give a quick report about each patient. One person may only need medication, while another is described as a "total."

The term is short for a patient who requires total care. They may need help eating, bathing, getting dressed, turning in bed, or moving from one place to another. Although the expression sounds impersonal, it’s simply a practical way for caregivers to communicate how much assistance someone needs.

Most people hear "frequent flyer" and think of an airline reward program. And that’s correct, but in an emergency room, the phrase has a very different meaning.

A frequent flyer is an informal nickname for patients who repeatedly return to the hospital, often due to chronic illness, recurring medical conditions, or other ongoing health issues. Behind the light-hearted nickname is often a difficult reality. Many of these patients are simply dealing with medical problems that require regular emergency care, and the expression is just a way to make the experience a bit lighter among the familiar faces of doctors and nurses.

Not all codes are for patients. The next time you’re in a hospital, look closely at what the nurse is pushing from room to room. It may look like a small rolling desk with a computer on top. Staff often call it a "WOW," short for "workstation on wheels."

As hospitals switched from paper charts to electronic medical records, these mobile computers became essential. Nurses use them to review test results, scan medications, update patient charts, and check doctors’ orders without leaving the bedside. The name sounds funny, but the technology helps caregivers spend more time with patients instead of walking back and forth to a nursing station.

After getting a shot or having blood drawn, most patients never think about where the used needle ends up. It certainly doesn't go into an ordinary trash can.

Hospitals place needles, scalpels, and other sharp medical instruments into special containers designed to prevent accidental injuries. These sturdy, puncture-resistant boxes are sealed when full and safely disposed of in accordance with strict health regulations. This not only protects nurses, but it also protects cleaning crews, waste handlers, and even the public from dangerous needle sticks. It’s one of the most important safety measures in every hospital, even though most patients never notice it.

If you’ve ever watched a medical drama, you've probably seen a patient become so agitated that several staff members rush into the room. In situations like that, a doctor or nurse may ask for a "B-52." But the name has nothing to do with numbers themselves; it actually comes from a medicine.

B-52 is hospital slang for a fast-acting injection used to calm down patients who are severely combative or at risk of harming themselves or others. The nickname comes from a commonly used combination of medications that usually include diphenhydramine, haloperidol, and lorazepam. It’s strictly reserved for when other methods of calming the patient haven’t worked.
