What does the serratus ventralis muscle do?
What does the serratus ventralis muscle do?
The serratus ventralis is composed of cervical and thoracic portions that originate from the cervical vertebrae and ribs and converge to insert on the medial surface of the scapula to form the sling support that suspends the thorax between the forelimbs.
Do cats have a serratus anterior?
The deep muscle group holds the body up towards the scapula when the cat is standing, and is composed of the serratus ventralis, trapezius, and rhomboideus muscles. These insert at the cranial angle and dorsal border of the scapula.
What muscles do serratus anterior work?
Serratus anterior muscle
| Serratus anterior | |
|---|---|
| Nerve | long thoracic nerve (from roots of brachial plexus C5, 6, 7) |
| Actions | protracts and stabilizes scapula, assists in upward rotation. |
| Antagonist | Rhomboid major, Rhomboid minor, Trapezius |
| Identifiers |
What is the action of serratus ventralis?
Action: pulls scapula forward (anterior) and laterally (abduction), rotates scapula upward.
What does the serratus ventralis dog?
The serratus ventralis is the muscle that transfers the weight of the body to the shoulder while the dog is standing; and when the dog jumps down and lands hard on his forelegs, it works as a shock absorber. The serratus ventralis gets its name from having the shape of a saw. The Latin term for saw is serrare.
Do cats have a gluteus maximus?
Cats, despite opinions to the contrary, DO have butt cheeks. Those shapely tufts of fur on a cat’s backside are hiding their gluteus maximus and medius muscles, the same muscles that define human butt cheeks. “They do have ‘butt cheeks’! They have a gluteus maximus and medius muscle on each side just like humans.”
Do dips work serratus anterior?
Dips are another pushing exercise that in tandem can strengthen the serratus anterior. But add-in scapular protraction at the top of your dip.
What does serratus ventralis look like in cats?
Serratus ventralis in the cat looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs. The name implies that it looks like a serrated knife. This is one of the five muscles that are grouped as muscles of the scapula, or sometimes as muscles that moor the scapula .
Where does the serratus ventralis move?
The serratus ventralis muscles arise from the third to seventh cervical vertebrae and the first eight to nine ribs and insert on the medial proximal aspect of each scapula. They sling the thorax between the forelimbs. Rupture of one or both of these muscles is a rare injury, caused by trauma. The proximal border of the scapula moves proximally.
Why is the ventralis called a serrated muscle?
The ventralis part of the name is because it is the lower (ventral) serrated style of muscle. There is also a serratus dorsalis which is a serrated type of muscle close to the top of the back (numbers 40 and 41 in this picture).
What is the structure of the serratus dorsalis?
The serratus dorsalis muscles are composed of slips extending from the middorsal line to the lateral surfaces of the ribs. The fibers do not extend all the way middorsally, but attach by aponeuroses. The fibers of the serratus dorsalis cranialis extend posteroventrally, and those of the serratus dorsalis caudalis extend anteroventrally.
