Study Notes
Biceps Brachii Long Head
- Flexes and supinates the elbow; weak flexor when long head is engaged
- Originates from the supraglenoid tubercle of the scapula
- Inserts at the radial tuberosity
Biceps Brachii Short Head
- Flexes and supinates the elbow; weak flexor when long head is engaged
- Originates from the coracoid process of the scapula
- Inserts at the radial tuberosity
Brachialis
- Primary action is flexion at the forearm
- Originates from the anterior shaft of the humerus
- Inserts at the ulnar tuberosity
Brachioradialis
- Flexes at the forearm; also acts as a supinator and assists in returning to a neutral "handshake" position
- Originates from the lateral epicondyle of the humerus
- Inserts at the styloid process of the radius
Triceps Brachii Lateral Head
- Responsible for extension at the elbow
- Originates from the superior lateral shaft of the humerus
- Inserts at the olecranon of the ulna
Triceps Brachii Long Head
- Contributes to elbow extension
- Originates from the infraglenoid tubercle of the scapula
- Inserts at the olecranon of the ulna
Triceps Brachii Medial Head
- Engages in elbow extension; also has a role in shoulder adduction
- Originates from the posterior shaft of the humerus, inferior to the radial groove
- Inserts at the olecranon of the ulna
Anconeous
- Functions to extend the elbow
- Originates from the posterior, inferior surface of the lateral epicondyle of the humerus
- Inserts at the lateral margin of the olecranon on the ulna
Supinator
- Performs supination of the forearm
- Originates from the lateral epicondyle of the humerus, annular ligament, and ridge near the radial notch of the ulna
- Inserts at the anterolateral surface of the radius, distal to the radial tuberosity
