Longus Capitis Muscle Anatomy
What is Longus Capitis Muscle? Longus capitis is a deeper anterior neck muscle that travels in front of the cervical spine. Combine with rectus capitis anterior, rectus capitis lateralis, longus cervicis, or the anterior scalene muscle, it creates the prevertebral layer of neck muscles. These muscles are wrapped or rolled up in the prevertebral layer of the cervical fascia. Bilateral contraction of longus capitis muscle flexes the combined head or…
Longus Colli Muscle Anatomy
What is Longus Colli Muscle? Longus Colli is a paired muscle situated on the anterior surface of the vertebral column. As such, it is often known as anterior prevertebral muscle along with the longus capitis, rectus capitis anterior, or the scalenus anterior muscles. The longus colli muscle (‘long muscle of the neck) is also called as longus cervicis since it spans the…
Rectus Capitis Anterior and Lateralis Muscle Anatomy
Rectus Capitis Anterior Muscle What is Rectus Capitis Anterior Muscle? Rectus capitis anterior muscle is 1 of the deeper neck muscles whose primary function is to flex the head on the neck at the atlantooccipital joint. This short strap muscle relates to the group of anterior vertebral muscles combined with the longus colli, longus capitis & the rectus capitis lateralis muscles. The anterior or the lateral neck…
Rectus Capitis Posterior Minor and Major Muscle Anatomy
Rectus Capitis Posterior Minor Muscle What is Rectus Capitis Posterior Minor Muscle? Rectus capitis posterior minor muscle is a coupled or paired muscle situated in the suboccipital compartment or area of the neck. It is the portion of the suboccipital muscle group which comprises 4 muscles in total, the other 3 being rectus capitis posterior major, obliquus capitis inferior or the obliquus capitis superior….
Obliquus Capitis Muscle Anatomy
Obliquus Capitis Superior Muscle What is Obliquus Capitis Superior Muscle? Obliquus capitis superior, or superior oblique, is a tiny coupled/paired muscle situated deeper in the upper cervical region, at the base of the occipital bone. It is 1 of the 4 muscles that comprise the suboccipital muscles group together with the rectus capitis posterior major, rectus capitis posterior minor, or the obliquus capitis…
Semispinalis Muscle Anatomy
What is the Semispinalis muscle? The semispinalis muscle relates to the transversospinalis muscles. The transversospinalis muscle group is a very deeper layer of muscles situated on either side of the spine. The semispinalis muscle is: The most superficial/upper layer of this muscle part. The bigger muscle mass is in the posterior part of the neck. It is responsible for…
Splenius Muscles Anatomy
What is Splenius Muscle? The splenius muscles of the head or the splenius muscle of the neck work combined so that the neck or the head can extend (tilt backward) or rotate. The splenius muscle of the head also called the splenius capitis, is a bigger muscle situated at the back of the neck. It is joined…
