Chapter 6, Problem 23SAE

Summary Introduction

To review:

Two muscles that reverse the movement of the deltoid muscle.

Introduction:

The deltoid muscles are the muscles of the shoulders. They are fleshy and triangle-shaped and are the suitable site for intramuscular injection. They originate from both the sides of the shoulder girdle from the spine of the scapula and end at the clavicle. They ultimately end up with the proximal humerus. They help in moving the arms.
