Study Notes
Anterior Arm Muscles
- Deltoid (anterior): Responsible for arm abduction at the shoulder and flexion of the arm.
- Brachialis: Primarily flexes the forearm at the elbow.
- Biceps brachii: Also assists in flexing the forearm; crucial for forearm supination.
- Brachioradialis: Flexes the forearm; particularly active during rapid movements or heavy lifting.
Posterior Arm Muscles
- Deltoid (posterior): Functions to extend the arm at the shoulder.
- Triceps brachii: Abducts the arm at the shoulder and extends the arm, crucial for pushing movements.
