BIOB33H3 Lecture Notes - Lecture 7: Iliacus Muscle, Adductor Longus Muscle, Palmaris Longus Muscle
Document Summary
The muscular system: appendicular musculature (based on chapter 11) Muscles of the pectoral girdle and upper limbs. Long head of triceps brachii: originates on the scapula and inserts on the olecranon. Long head of biceps brachii: originates on the scapula and inserts of the radial tuberosity of the. Biceps brachii: flexes at the elbow and shoulder. Triceps brachii: extension at elbow, extension and adduction at elbow (long head) Long head: extension at the elbow and adduction at the shoulder. On ulnar (medial) side - flexor carpi ulnaris: flex and adduct the wrist. Palmaris longus: flexion at the wrist wrist and finger (deeper) muscles that produce extension extensors from lateral epicondyle (on lateral side) of humerus. Extensor carpi radialis longus: extend and abduct at the wrist. Extensor carpi radialis brevis: extend and abduct at the wrist. Extensor carpi ulnaris: extension and adduction at the wrist. Relatively large muscles that perform flexion and extension at the joints of the fingers.
