Rectus capitis posterior major muscle Anatomy arises by a pointed tendon from the spinous process of the axis, and, becoming broader as it ascends, is inserted into the lateral part of the inferior nuchal line of the occipital bone and the surface of the bone immediately below the line. origin : Spinous process of the…
Rectus capitis posterior minor muscle Anatomy arises by a narrow pointed tendon from the tubercle on the posterior arch of the atlas, and, widening as it ascends, is inserted into the medial part of the inferior nuchal line of the occipital bone and the surface between it and the foramen magnum, and also takes some…
Obliquus capitis superior muscle Anatomy a small muscle in the upper back part of the neck and is one of the suboccipital muscles and part of the suboccipital triangle. Origin Lateral mass of atlas. Insertion Lateral half of the inferior nuchal line. Nerve Supply Suboccipital nerve. Blood Supply The obliquus capitis superior muscle and the…
Scalene Posterior Muscle Anatomy The scalene muscles are three paired muscles (anterior, middle, and posterior), located in the lateral aspect of the neck to the floor of the posterior triangle of the neck. a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. The posterior…
The scalenus medius muscle is one of the three scalene muscles located in the lateral neck region. It lies deeper than the anterior scalene and superficial to the posterior scalene. Scalene medius Muscle Anatomy The largest and longest muscle in the scalene group of lateral neck muscles is the middle scalene, also known as scalenus…
Scalene anterior Muscle is a group of three pairs of muscles in the lateral neck, namely the anterior scalene. It is located deeply just behind the Sternocleidomastoid muscle. The brachial plexus and subclavian artery runs between the anterior and middle scalene muscles. This provides an important anatomical locations for anaesthetics to do an interscalene block….
Introduction Scalene Muscle is a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. The cervical tract is laterally positioned and the scalene muscles are deep. Because the brachial plexus and the cervical plexus are involved in their function, their innervation is complex. Their functions…
The Rectus Capitis Lateralis is one of the small suboccipital muscles located in the upper neck region at the back of the head. It is part of a group of four muscles known as the suboccipital muscles. These muscles are responsible for various movements and stabilizing the head and neck. Rectus capitis lateralis muscle Anatomy…
Rectus Capitis Anterior Muscle Anatomy The rectus capitis anterior (also rectus capitis anterior muscle, anterior rectus capitis, Latin: musculus rectus capitis anterior) is a short muscle located anterior to the vertebral column, stretching between the atlas and the base of the skull. It is involved in the flexion of the neck. Along with the rectus…
Longus Capitis Muscle Anatomy The longus capitis is a prevertebral muscle of the neck. Situated anterior to the vertebral column it is involved in flexion and rotation of the head and cervical vertebrae. is broad and thick above, narrow below, and arises by four tendinous slips. origin anterior tubercles of the transverse processes of the…
