Study Notes
Front of Forearm
- Contains the anterior compartment muscles.
- These muscles are responsible for flexion of the wrist and fingers, and pronation of the forearm.
Back of Forearm
- Contains the posterior compartment muscles.
- These muscles are mainly responsible for extension of the wrist and fingers, and supination of the forearm.
Classify Elbow and Radioulnar Joints
- Elbow joint is a synovial hinge joint (flexion/extension)
- Radioulnar joints are synovial pivot joints.
Articulating Bones
- Humerus, radius and ulna
- Articulating bones of the proximal radioulnar joint are the radius and ulna
- Articulating bones of the distal radioulnar joint are the radius and ulna.
Ligaments of the Elbow Joint
- Radial collateral ligament
- Ulnar collateral ligament
- Annular ligament
- Oblique cord
Movements of Elbow Joint
- Flexion
- Extension
- Slight supination
- Slight pronation
Muscles of Elbow Joint
- Biceps brachii (flexion)
- Brachialis (flexion)
- Triceps brachii (extension)
- Anconeus (extension)
Muscles of Radioulnar Joints
- Supinator
