BMS 250 Lecture Notes - Lecture 10: Palmaris Longus Muscle, Extensor Digitorum Muscle, Calcaneus
Document Summary
Flexion- shortening the muscle and bending or decreasing the angle between bones of the lumb. Extension- lengthen the muscle and increase the angle between the bones of the limb. Inversion- soles of feet point toward one another. Eversion- soles of feet point outward of one another. Depression- back to anatomical position, move back to inferior parts. Flexor carpi radialis- flexion: wrist abduction: hand anterior. Flexor carpi ulnaris- flexion: wrist adduction: hand anterior. Extensor carpi radialis longus- extension: wrist abduction: hand posterior. Extensor carpi radialis brevis- extension: wrist abduction: hand posterior. Extensor digiti minimi- extension: wrist + digit 5 origin- lateral epicondyle of humerus insertion: base of middle/distal phalanx of 5th phalanges posterior. Extensor carpi ulnaris- extension: wrist and adduction: hand posterior. Sartorius- flexion- lower leg and thigh and lateral rotation of thigh- anterior origin: superior anterior iliac spine insertion: proximal medial tibia. Adductor longus- flexion: thigh and adduction: thigh anterior. Adductor brevis: flexion: thigh adduction: thigh anterior deep.
