Muscle Of The Week... Abductor Pollicis Brevis
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
Abductor Pollicis Brevis
KenHub explains the Abductor Pollicis Brevis as follows":This muscle arises from the tubercles of the scaphoid and trapezium, and from the flexor retinaculum. Its short tendon courses to the base of the proximal phalanx and the dorsal aponeurosis of the thumb via the radial sesamoid bone. The abductor pollicis brevis lies underneath the skin superficially."
The function of Abductor Pollicis Brevis abduct the thumb.
