Question
Chapter 8, Problem 1WYL
Summary Introduction
To determine:
The scapular angle where the glenoid cavity is present.
Introduction:
The scapula is a broad, flat, and triangular bone. Several large projections extend from the scapula and provide surface area for muscle and ligament attachments. The spine of the scapula is a ridge of bone on the posterior side of the scapula.
Expert Solution & Answer
Explanation of Solution
The lateral scapular angle is composed of the cup-shaped and shallow glenoid cavity. The glenoid cavity articulates with the humerus, which is the bone of the arm. Tubercles on the superior and inferior edges of the glenoid cavity serve as attachment sites for the muscles that position the shoulder and arm.
