Brachialis | Elbow flexor |
Extensor carpi radialis | extends and adducts wrist |
Flexor Digitorum | From anterior/medial ulna, splits into four tendons running through carpal tunnel to distal phalanges of fingers, producing flexion of all finger joints. |
Extensor digitorum | From elbow, splits into four tendons, each splitting tnto three bands, to the posterior second and first knuckles, producing extension of all finger joints and wrist. |
Pollicis Flexor | From radius to thumb, bends thumb inward toward palm |
Pollicis Abductor | From ulna and radius to lateral base of thumb, brings entire thumb toward palm. |
Pollicis Extensor | From posterior radius to first and second knuckles of thumb, causing thumb extension |
