Flashcards

Serratus Anterior

A large, flat muscle that helps with arm protraction, upward rotation, and depression of the scapula, located in the chest. It is innervated by the long thoracic nerve.

Long Thoracic Nerve

A long nerve that innervates the serratus anterior muscle, responsible for protracting and rotating the scapula.

Deltoid

A triangular muscle covering the shoulder joint, involved in arm abduction, flexion, and extension. It's innervated by the axillary nerve.

Axillary Nerve

A nerve that innervates the deltoid and teres minor muscles, responsible for shoulder abduction and rotation.

Pectoralis Major

A large, fan-shaped muscle in the chest, responsible for arm flexion, adduction, and medial rotation. It is innervated by the lateral and medial pectoral nerves.
