What is the function of the Clavotrapezius?
Its origin is the superior nuchal line and median dorsal line and its insertion is the clavicle. Its action is to draw the clavicle dorsally and towards the head.

Where is the Spinodeltoid?
Spinodeltoid - This is the most posterior muscle of the deltoid group. It originates on the spine of the scapula, to which it runs parallel, and inserts on the humerus. It is readily identified by its rectangular shape and its relationship to the surrounding muscles.
Is Acromiodeltoid a flexor?
Its anterior end passes deep to the triangular acromiodeltoid. These muscles are flexors and lateral rotators of the humerus.
What are the 3 main functions of the latissimus dorsi?
The latissimus dorsi assists in depression of the arm with the teres major and pectoralis major. It adducts, extends, and internally rotates the shoulder.
Do cats have a latissimus dorsi?
Latissimus dorsi on cat is very similar to that of a human!
Is Spinodeltoid a flexor?
The spinodeltoid arises from the scapula spine and inserts on the proximal portion of the humerus. The acromiodeltoid and spinodeltoid work synergistically to flex the humerus and rotate it outward.
What is the action of supraspinatus?
As part of the Rotator Cuff, supraspinatus helps to resist the gravitational forces which act on the shoulder joint to pull from the weight of the upper limb downward. It also helps to stabilize the shoulder joint by keeping the head of the humerus firmly pressed medially against the glenoid fossa of the scapula.
What are lats?
The latissimus dorsi muscles, known as the lats, are the large V-shaped muscles that connect your arms to your vertebral column. They help protect and stabilize your spine while providing shoulder and back strength.
How many heads does the Spinodeltoid muscle of the rat have?
Spinodeltoid - runs between the scapular spine and the upper arm. Pulls the scapula away from the ribs. Triceps brachii - this is a muscle with three heads. It runs between the scapula and humerus and the ulna.

What is Subscap?
The subscapularis is the largest, strongest muscle of the rotator cuff. The rotator cuff muscles are important in shoulder movement and help maintain glenohumeral joint stability. The subscapularis muscle lies at the anterior surface of the scapula.
