Study Notes
Chest Muscles
- Pectoralis Major: A large muscle located in the upper chest, extending from the shoulder to the breastbone, responsible for creating the bulk of the chest, commonly referred to as "pecs."
- Pectoralis Minor: Situated beneath the pectoralis major, this muscle connects the ribs to the coracoid process of the scapula, playing a role in the movement of the shoulder.
Neck Muscles
- Sternocleidomastoid: A significant muscle that runs from the mastoid process at the base of the skull to the sternum and clavicle, responsible for head rotation and flexion of the neck.
Shoulder Muscles
- Deltoid: The muscle that covers the shoulder joint, responsible for arm abduction, flexion, and extension.
- Biceps Brachii: Located on the anterior part of the upper arm, this muscle is crucial for elbow flexion and forearm supination.
Other Important Muscles
- Subscapularis: Found in the subscapular fossa, it is one of the rotator cuff muscles, playing a key role in shoulder stability and movement.
- Serratus Anterior: Connects the ribs to the scapula, important for protraction and upward rotation of the shoulder blade.
