Question
Chapter 12, Problem 12.1.3AYLO
Summary Introduction
To determine:
About the trapezius, levator scapulae, rhomboid minor, and rhomboid major.
Introduction:
Muscles acting on the pectoral girdle arise from the axial skeleton and get inserted into the clavicle and scapula. The scapula is responsible for various movements, such as rotation, elevation and depression, and protraction and retraction. The pectoral girdle muscles are divided into anterior and posterior groups.
