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).
What is the action of the Spinodeltoid?
Muscles of the Neck, Shoulder, Chest and Abdomen
Muscle Name | Origin | Action |
---|---|---|
Spinodeltoid | Spine of Scapula | Retracts humerus Adducts humerus |
Spinotrapezius | Spines of thoracic vertebra | Draws scapula dorsally Draws scapula caudally |
Sternomastoid | Sternum | Turns head Depresses head |
Supraspinatus (Deep) | Scapula | Extends humerus (Rotator cuff) |
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.
Where are the trap muscles?
The trapezius is a muscle that starts at the base of your neck, goes across your shoulders and extends to the middle of your back. The trapezius (traps muscle) helps you move your head, neck, arms, shoulders and torso. It also stabilizes your spine and helps with posture.
What is the Clavodeltoid?
Clavodeltoid (cat) The major muscle group of the shoulder is the deltoid group. The clavodeltoid originates from the clavicle and inserts on the ulna. This muscle flexes the forearm. The acromiodeltoid lies posterior to the clavodeltoid.
What is Subscap?
Muscles. The subscapularis muscle originates at the subscapular fossa and inserts into the lesser tubercle of the humerus. The muscle internally rotates and adducts the humerus.
Where is the Spinodeltoid?
Spinodeltoid. A stout and short muscle lying posterior to the acromiodeltoid. It lies along the lower border of the scapula, and it passes through the upper arm, across the upper end of muscles of the upper arm. It originates at the spine of the scapula and inserts at the deltoid ridge.
What is the action of the Epitrochlearis?
The epitrochlearis is a small accessory muscle in the arm. In humans, it appears to be a vestigial muscle that has no action, but instead only serves…
What is the action of serratus ventralis?
Action: pulls scapula forward (anterior) and laterally (abduction), rotates scapula upward.
What is the function of the lower trapezius?
The lower trap helps to depress the scapula (shoulder blade) as well as help the upper fibers of the trapezius upwardly rotate the scapula. We focus on activating the lower traps to help stabilize the shoulder blades during overhead movements.
How do you work upper traps?
3. Upright row
- Stand up straight.
- With your fists clenched, pull up your fists as high as you can while bending your elbows, keeping your hands close to the front of your body.
- Hold for a count of two.
- Release your arms back into a relaxed position, fists still clenched.
- Repeat 20 times.
What is the clavodeltoid muscle in cats?
Both pictures show an anterior view of the cat’s clavodeltoid muscle (aka clavobrachialis), which is analogous to the human “deltoid” muscle. Simply think of this one as the “shoulder muscle” for the lab practical. Description of clavodeltoid – it is the most superficial muscle of the shoulder.
What is the difference between the clavodeltoid and acromiodeltoids?
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.
What is the difference between the Spinotrapezius and clavodeltoid?
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. The clavodeltoid originates from the clavicle and inserts on…
How do the acromiodeltoid and spinodeltoids work synergistically?
The acromiodeltoid and spinodeltoid work synergistically to flex the humerus and rotate it outward. There are two back muscles associated with these two groups of muscles; they are the levator scapulae ventralis and the latissimus dorsi.
