18-02-27 scapula and acromion for WPAll of our 200+ bones have names, which facilitates describing them when we cannot actually hold them or point directly at them. It might be easier to remember the names if they were familiar ones like Robert, Sally, and Kevin, but no such luck. Latin was the original language of science, so the bones received Latin names. Some of those were derived from Greek. All were purely descriptive and widely understood, providing that you spoke Latin. For example, the shoulder blade is mostly flat and triangular. An anatomist picked one up, pondered a bit, and decided it resembled the blade on a shovel or spade. He named it scapula, Latin for shovel.

18-02-27 wrist bones Vesalius for WPThe eight wrist bones are another good example of simplicity. At first they were just numbered, but then they received Latin names, including scaphoid, lunate, triquetrum, and pisiform. Those Latin names are hard for us to remember, but they merely describe the bones’ shapes: boat, crescent moon, three-corners, and pea-shaped, respectively. 18-02-27 wrist bones and shapes for WP

(To aid memory, medical students use this mnemonic (or dirtier versions) to learn the names of the wrist bones: She Loves To Please The Tall Campus Hero.)

Not only do the bones have names that are vaguely descriptive, so do all of their bumps, ridges, and crannies. For instance, the tip of your shoulder is your acromion. This word is derived from the Greek acro meaning highest or topmost (as in acropolis—high city) and from omion, meaning shoulder. That makes sense, as does olecranon to describe the tip of your elbow. It comes from Greek, olene for elbow plus kranion for head. But what about the bumps on both sides of your ankle? They are malleoli. Malleus means hammer. What were they thinking?

Then consider that the hip joint’s deep socket in the pelvis is officially known as the acetabulum—pretty strange to a non-Latin speaker, but it is simply named for its resemblance to a vinegar cup: acetum for vinegar plus -abulum for container. I do not know, however, what the early anatomists did with cups of vinegar. Maybe it was just wine that had gone bad, and they drank it anyway just before naming the malleoli.


Doctors today buy into the Greek-and-Latin-naming tradition both necessarily and willingly. By using uniform terminology, professionals can understand oral presentations and written journal articles from around the world. Then too, consciously or unconsciously, tossing ancient expressions around separates the wizards from the uneducated masses. This makes knowledge privileged, and hence, valuable. Without holding the secret keys to the kingdom, doctors could suddenly lose respect. 18-02-27 foramen magnum for WP

Consider for instance, the awe-inspiring term, foramen magnum–the one-inch diameter hole at the base of the skull from whence the spinal cord emerges. Foramen magnum sounds grand and important, perhaps even magical, doesn’t it? It translates into English, however, as big hole.

    1. Your teachers were actually understating the case. You have a bunch of holes, including the foramen ovale and the foramen rotundum, oval hole and round hole, respectively, but none are as large as the foramen magnum. Don’t the Latin terms sound more scholarly?

  1. Roy,
    Very interesting. My latin was limited to Catholic Mass so your tutoring has been very helpful. I enjoy your blog and I am learning a lot. Thanks for thinking of us.

  2. I am always impressed by the range of your scholarship, and probably more importantly, by your ability and desire to pass it on. Your contributions to the hand surgery community are beyond impressive. We are all in your debt.

    1. Hi Vincent, I suppose the answer depends on who you ask and when. I have seen bacula that had been broken and then healed. Remember too that females of certain species have an analogous bone. Best wishes, Roy

  3. Roy – I learned so many valuable and practical lessons with you as a resident, doing my rotations, and also in the rabbit lab! Thank you for continuing to teach me through your fascinating posts. Bones are definitely the most interesting tissue in the body!

    1. Hi Bob,
      Nice to hear from you. I agree, bone rules–not only in supporting vertebrate life, but later in reflecting earth history and human culture. You and I are privileged to be able to treat it. Most people have never even seen living bone. I have NO interest in EVER seeing mine. Best wishes, Roy
