Why is it called longus capitis?
The longus capitis muscle (Latin for long muscle of the head, alternatively rectus capitis anticus major), is broad and thick above, narrow below, and arises by four tendinous slips, from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebræ, and ascends, converging …
What is the 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.
How rare is a Palmaris longus?
The palmaris longus is a muscle visible as a small tendon located between the flexor carpi radialis and the flexor carpi ulnaris, although it is not always present. It is absent in about 14 percent of the population; however, this number can vary in African, Asian, and Native American populations.
Are two Palmaris longus rare?
Tendon of the Palmaris longus crosses the retinaculum and fans out as a flat sheet which eventually continues as palmar aponeurosis. Variations of PL muscle are not uncommon. It has been estimated that in about 11% of cases, they are found to be absent (2, 3).
What is longus capitis?
What is the function of the longus capitis?
This muscular band attaches onto the region of the occiput anterior to the foramen magnum and posterior to the pharyngeal tubercle. The longus capitis muscle functions to flex the head (Cagnie et al., 2010) and is innervated by branches of the anterior primary divisions of C1 to C3.
Longus capitis is a long flat muscle of the anterior neck. It runs up the length of the cervical spine, adjacent to the vertebral bodies. Longus capitis muscle originates from its inferior aspect, as four small muscle straps that run from the anterior tubercles of transverse processes of the third, fourth, fifth and sixth cervical vertebrae.
How does the anterior ramus of C1 supply the longus capitis?
The anterior ramus of C1 emerges lateral to the atlanto-occipital joint then passes between the rectus capitis anerior and rectus capitis lateralis muscles before penetrating and supplying the longus capitis muscle. The nerve then gives a branch to the hypoglossal nerve.
What is the difference between bilaterally and unilaterally activated longus capitis?
By contracting bilaterally the longus capitis flexes the head, while by contracting unilaterally the activated muscle rotates and tilts the head to the ipsilateral side. The longus capitis is innervated by branches from the anterior rami of the 1st to 3rd cervical spinal nerves (C1 – C3) from the cervical plexus.
How does the longus capitis enter the hypoglossal nerve?
Longus capitis muscle. The anterior ramus of C1 emerges lateral to the atlanto-occipital joint then passes between the rectus capitis anerior and rectus capitis lateralis muscles before penetrating and supplying the longus capitis muscle. The nerve then gives a branch to the hypoglossal nerve.
