What does the Clavobrachialis muscle do?

Human information: This is one of the five muscles in the group we refer to as the muscles that move the arm (not including the rotator cuff muscles).

Why is it called Acromiotrapezius muscle?

Acromiotrapezius is the middle trapezius muscle. It covers the dorsal and lateral surfaces of the scapula. Its origin is the neural spines of the cervical vertebrae and its insertion is in the metacromion process and fascia of the clavotrapezius.

What is the insertion of the Spinotrapezius?

Spinotrapezius, also called thoracic trapezius, is the most posterior of the three trapezius muscles. It is triangular shaped. Posterior to the acromiotrapezius and overlaps latissimus dorsi on the front. Its origin is the neural spines of the thoracic vertebrae and its insertion is the scapular fascia.

What is the function of the Spinotrapezius?

The spinotrapezius arises from the spinous processes of thoracic vertebrae and inserts on the fascia covering the scapular muscles. Its action is to adduct the scapula and pull it posteriorly.

What is the action of Pectoantebrachialis?

The major action of these muscles is adduction of the forelimb (i.e. the front leg is drawn toward the midline). There are four subdivisions of the pectoral group in the cat. The pectoantebrachialis is the most superficial muscle of the pectoral group.

What makes up the trapezius group in cats?

Trapezius. In the cat there are three thin flat muscles that cover the back, and to a lesser extent, the neck. They pull the scapula toward the mid-dorsal line, anteriorly, and posteriorly.

Where is the Acromiotrapezius on a cat?

What is the action of Acromiotrapezius on cat?

The acromiotrapezius (which arises on the middorsal line of the neck and thorax and inserts on the metacromion and spine of the scapula) adducts the scapula. The spinotrapezius arises from the spinous processes of thoracic vertebrae and inserts on the fascia covering the scapular muscles.

What is the action of Spinotrapezius in cat?

The spinotrapezius arises from the spinous processes of thoracic vertebrae and inserts on the fascia covering the scapular muscles. Its action is to adduct the scapula and pull it posteriorly. The major muscle group of the shoulder is the deltoid group.

What is the action of Spinotrapezius?

action: retracts (adducts), depresses and. rotates scapula. This is one of the five muscles that are grouped as muscles of the scapula, or sometimes as muscles that moor the scapula.

What is the difference between the Spinotrapezius and the clavotrapzius?

The spinotrapezius arises from the spinous processes of thoracic vertebrae and inserts on the fascia covering the scapular muscles. Its action is to adduct the scapula and pull it posteriorly. The clavotrapezius arises from the back of the skull and middorsal line of the neck and inserts on the clavicle.

What muscles do cats have in their back and shoulder?

The two major muscle groups of the back and shoulder of the cat are the trapezius group and the deltoid group. The clavotrapezius arises from the back of the skull and middorsal line of the neck and inserts on the clavicle. Its action is to extend the humerus in a forward direction.

What is the function of the spines on a cat’s tongue?

The cat’s tongue has sharp spines, or papillae, useful for retaining and ripping flesh from a carcass. These papillae are small backward-facing hooks that contain keratin, and also assist in their grooming. The papillae also help hold water on the tongue while drinking.

Where is the deltoid muscle located in a cat?

The deltoid muscles lie just lateral to the trapezius muscles, originating from several fibers spanning the clavicle and scapula, converging to insert at the humerus. Anatomically, there are only two deltoids in the cat, the acromiodeltoid and the spinodeltoid.
