The sternomastoid, also known as the sternocleidomastoid, is a muscle located in the neck. There are two of them in the human neck and it is one of the largest cervical muscles in the body.
The muscle that is considered the strongest jaw muscle is called the masseter muscle.
The connective tissue that connects muscle to muscle is called fascia.
Smooth muscle, skeletal muscle, and cardiac muscle all contract in response to signals from the nervous system or hormones. However, the contraction mechanism of smooth muscle is different from that of skeletal and cardiac muscle. Smooth muscle contracts more slowly and can sustain contractions for longer periods of time compared to skeletal and cardiac muscle. Additionally, smooth muscle does not have striations like skeletal and cardiac muscle, which gives it a more uniform appearance.
A muscle relaxant works by targeting the nervous system to reduce muscle contractions, helping to alleviate muscle tension or spasms.
The anatomical term for the calf muscle is the gastrocnemius muscle.
The sternocleidomastoid in the human is homologous to the sternomastoid muscle of the cat.
Sternomastoid (cat) corresponds to the medial portion of the sternocleidomastoid (human).origin: manubrium and median raphe.insertion: lateral half of lambdoidal ridge and mastoid portion of temporal bone as far as the mastoid process.The sternomastoid muscle defines the anterior triangle of the neck. In humans it is the thick strap like muscle that turns the head to the left or right.
Humans have a sternocleidomastoid muscle, but cats do not. In a cat, the sternomastoid muscle defines the anterior triangle of the neck.
Yes. The main cause is sternomastoid muscle.
There are two sternomastoid muscles in the human body. The sternomastoid is also known as the sternocleidomastoid.
Sternomastoid, lying in the neck, is well superior to rectus abdominis which lies in the anterior abdominal wall.

sternomastoid
If the head of the neck is fixed, then it is possible for the muscles to raise the clavicle and manubrium sterni, and hence the ribs, so that they act as accessory muscles of respiration.
the wrist joint where the radial pulse may be felt and the neck just above the sternomastoid muscle where the carotid pulse may be felt
The stenrocleidomastoid muscle bilaterally does neck extension, while unilaterally, they laterally flex the Neck to the same side of the muscle contracting, and rotates th neck to the contra lateral side. So if you rotate to the left, the right sternocleidomastoid muscle is working. The right stenrocleidomastoid will also cause right lateral flexion( side bending)
