Study Notes
Superficial Group of Forearm Muscles
- Originates from the medial epicondyle of the humerus.
- Comprises muscles that cross the elbow joint.
Muscle Organization from Lateral to Medial
-
Pronator Teres
- Functions to pronate the forearm.
- Passes superficial to the flexor muscles.
-
Flexor Carpi Radialis
- Acts on wrist flexion and radial deviation.
- Serves as a landmark for identifying the radial artery.
- Positionally fails to cross the elbow joint.
-
Palmaris Longus
- Not universally present; absent in some individuals.
- Aids in wrist flexion, primarily passes through distal structures.
-
Flexor Carpi Ulnaris
- Important for wrist flexion and ulnar deviation.
- Serves as a guide to the ulnar artery and nerve.
- Fails to cross the elbow joint.
Anterior View of the Forearm
- Illustrates the superficial muscles and their organization.
- Demonstrates the functional anatomy critical for forearm movements.
