The epitrochleoanconeus muscle (anconeous epitrochlearis muscle, anconeus-epitrochlearis or anconeus sextus) is a small accessory muscle of the arm which runs from the back of the inner condyle of the humerus over the ulnar nerve to the olecranon.
Where is Acromiotrapezius?
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 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.
Do humans have a Pectoantebrachialis?
Pectoantebrachialis & xiphihumeralis are chest muscles in the cat. These muscles are missing in the human. Clavodeltoid, acromiodeltoid, & spinodeltoid in the cat. There is one deltoid in the human.
What are chest muscles called?
pectoralis musclepectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder. There are two such muscles on each side of the sternum (breastbone) in the human body: pectoralis major and pectoralis minor.
What is the largest muscle in the chest?
The pectoralis majorThe pectoralis major is the superior most and largest muscle of the anterior chest wall.
What is the primary action of the masseter quizlet?
MASSETER MUSCLE ACTION. The action of the muscle when there is bilateral contraction of the entire muscle is to elevate the mandible, raising the lower jaw Elevation of the mandible occurs during the closing of the jaws.
What are the actions of the masseter quizlet?
What are the actions of the masseter and the temporalis? Temporalis elevates and retracts the mandible against the maxilla with great force. The masseter raises the mandible against the maxillae with great force.
Why is the masseter the strongest muscle?
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars. The uterus sits in the lower pelvic region.
Where is your masseter muscle?
Your masseter muscle is your primary chewing muscle — not the only one, but the main one — and it covers the sides of the jaw just behind the cheeks. It's also the main muscle that clenches your jaw and grinds your teeth, unfortunately, and it's one of the most common locations for trigger points in the human body.
What is the origin insertion and function of the cat masseter muscle?
The Masseter is a great, powerful, and very thick muscle covered by a tough, shining fascia lying ventral to the zygomatic arch, which is its origin. It inserts into the posterior half of the lateral surface of the mandible. Its action is the elevation of the mandible (closing of the jaw).
What is the origin of the Pectoantebrachialis?
Origin: arrises in two heads from medial epicondyle of humerus, other from olecranon. Insertion: middle of ulna they join and insert on ulnar side of carpals. Function: flexor of wrist.
What is the origin of the Acromiotrapezius?
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 origin of the Xiphihumeralis?
The fourth subdivision of the pectoral group, the xiphihumeralis, arises from the xiphoid process of the sternum posterior to the pectoralis minor. The xiphihumeralis is a thin band of muscle which runs lateral to the pectoralis minor and inserts on the proximal end of the humerus.
What are the two back muscles?
There are two back muscles associated with these two groups of muscles; they are the levator scapulae ventralis and the latissimus dorsi. The levator scapulae ventralis is a band-like muscle lying between the clavotrapezius and the acromiotrapezius. It originates from the skull and atlas to insert on the scapula.
Where does the clavodeltoid originate?
The clavodeltoid originates from the clavicle and inserts on the ulna. This muscle flexes the forearm. The acromiodeltoid lies posterior to the clavodeltoid. It arises from the acromion process of the scapula and inserts on the spinodeltoid muscle.
Which adducts the scapula?
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 muscle group is the back of the cat?
Muscles of the 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.
What is the function of the Clavotrapezius?
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 are traps used for?
The trapezius, commonly referred to as the traps, are responsible for pulling your shoulders up, as in shrugging, and pulling your shoulders back during scapular retraction.
Do traps count as shoulders?
Are traps shoulders or back? While the traps allow shoulder movement and attach to the scapula, they are considered part of the back. It’s a three-part muscle that attaches at the base of your skull and continues down to the middle of your spine.
What is the difference between clavotrapezius and clavodeltoid?
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. The clavodeltoid originates from the clavicle and inserts on the ulna.
