Final answer:
The inferior angle of the scapula serves as an insertion point for the teres major muscle. It is an important attachment point for shoulder and upper limb muscles. The scapula also has a shallow depression called the glenoid cavity, which forms the shoulder joint with the humerus bone.
Step-by-step explanation:
The inferior angle of the scapula serves as an insertion point for the teres major muscle. It is the most inferior portion of the scapula and is located between the medial and lateral borders. This angle is particularly important because it functions as the attachment point for several powerful muscles involved in shoulder and upper limb movements.
The scapula is a triangular bone that has three sides called the medial, lateral, and superior borders. The inferior angle is one of the corners of the scapula.
The scapula also has a shallow depression called the glenoid cavity or glenoid fossa, which articulates with the humerus bone of the arm to form the glenohumeral joint or shoulder joint.
