Muscle Of The Week... Abductor Pollicis Longus

Hi There

We are busy with all the ABductor muscles. This means muscles that pulls movement away from the mid line of the body!

Abduct- The smart way to clarify any movement that is done away from the mid line of the body or extremity. Easy way to remember is that aliens abduct humans FROM earth TO space. So the movement we are carrying out moves away FROM the midline TO where the movement takes place. 
I also think of a Jumping Jack to explain this movement. As we jump out with out legs and swing arm open and over we are abducting the legs and arms.

Proximal means  nearest point the joint 
Distal means furthers point from the joint


This week we add Brevis to the list of descriptive words in anatomy.
Brevis is the Latin word that means "short" and this brings us to Longus, which ; you've guessed it..."long".

Our list so far:
Abduction,Proximal,Distal,Brevis...and Longus!! 

Remember professionals need a language that can be understood internationally. It makes sense no matter where you are a doctor needs to be able to understand the body and communicate what he has done to the body and where it has been done.  I mean can you think of what might go wrong it there is a language barrier between a surgeon and the diagnosis doctor? You might lose a kidney or undergo a wrong procedure. Also Latin is a "dead" language.Meaning it does not change and evolve because we do not use it anymore as a means to communicate. But it still is the bases of a lot of languages and as you've now seen medical terminology.  Piont is; it doesn't change so everyone right around the world studying the body is on the same page irrespective of their language
