What action does the obliquus capitis superior do?

What action does the obliquus capitis superior do?

Function. Working bilaterally, obliquus capitis superior extends the head on the neck at the atlanto-occipital joint. It laterally flexes the head to the ipsilateral side when working unilaterally. The muscles most prominent role is as a postural muscle, whereby it stabilizes the atlanto-occipital during head movements …

What does the rectus capitis do?

Rectus capitis muscle is involved in extension of the head on the neck.

What causes suboccipital muscle pain?

The suboccipital muscles commonly become tense and tender due to factors such as eye strain, wearing new eyeglasses, poor ergonomics at a computer workstation, grinding the teeth, slouching posture, and trauma (such as a whiplash injury).

What is the function of the Splenius capitis?

Function. Bilaterally, the splenius capitis muscles extend and hyper-extend the head and neck. However, acting unilaterally, the muscle flexes and rotates the head and neck to the same side; particularly in the superior and inferior lateral oblique movements.

What is longus capitis?

The longus capitis muscle is a prevertebral muscle of the neck that is innervated by muscular branches of the cervical plexus. In isolation longus capitis acts to laterally flex and rotate the head.

What is the rectus?

Rectus abdominis, informally known as the abs muscle, is a long muscle of the anterior abdominal wall. In those with low body fat, it is clearly visible beneath the skin forming the ‘six pack’. It extends from the rib cage all the way to the pubic bone.

What causes Suboccipital muscle pain?

What is the suboccipital triangle?

The suboccipital triangles are a paired triangular-shaped space formed by the configuration of three paired muscles in the posterior neck between the occipital bone, C1 and C2.

How do you treat suboccipital pain?

Suboccipital headaches are improved with over-the-counter NSAIDs, ice, stretching, therapy, electric, ultrasound, and cold laser treatments. Goals of treatment are to decrease muscle spasms of the suboccipital muscles and trapezius.

What is the obliquus capitis inferior?

The naming of this muscle may be confusing, as it is the only capitis (L. “head”) muscle that does NOT attach to the cranium. The obliquus capitis inferior muscle, like the other suboccipital muscles, has an important role in proprioception. This muscle has a very high density of Golgi organs and muscle spindles which accounts for this.

What does the inferior oblique muscle do?

Inferior oblique muscle (Musculus obliquus inferior) Inferior oblique is a thin, narrow muscle of the eye. It is one of the 6 extraocular muscles, also referred to as the extrinsic muscles of the orbit. Like the other eye muscles, inferior oblique is named by its position within the orbit, relative to the eyeball.

Which suboccipital muscle does not insert onto the skull?

The obliquus capitis inferior muscle is the only muscle of the suboccipital group that does not insert onto the skull. Instead it spans the first and second cervical vertebra.

What does the capitis do in the neck?

It lies deep to the semispinalis capitis and trapezius muscles. The muscle is responsible for rotation of the head and first cervical vertebra (atlanto-axial joint). It forms the lower boundary of the suboccipital triangle of the neck. The naming of this muscle may be confusing, as it is the only capitis (L.
