Origins, insertions, innervation and functions of the suboccipital muscles. The suboccipital region is a muscle compartment, located inferior to the external occipital protuberance and the inferior nuchal line. These are anatomical landmarks on the occipital bone of the skull.
The suboccipital muscles are a group of muscles defined by their location to the occiput. Suboccipital muscles are located below the occipital bone . These are four paired muscles on the underside of the occipital bone; the two straight muscles ( rectus ) and the two oblique muscles ( obliquus ).
The suboccipital muscles are a group of four muscles situated underneath the occipital bone. All the muscles in this group are innervated by the suboccipital nerve. They are located within the suboccipital compartment of the neck; deep to the sternocleidomastoid, trapezius, splenius and semispinalis muscles. They collectively act to extend and ...
The suboccipital muscles form a suboccipital triangle, which can be used as a consistent marker for the location of the vertebral artery and suboccipital nerve. The rectus outlines the suboccipital triangle capitis posterior major, obliquus capitis superior, and obliquus capitis superior.
The suboccipital muscles are a group of four paired deep muscles located at the base of the occipital bone. Their main actions are to extend and rotate the head. They consist of the rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis superior and obliquus capitis inferior.
The suboccipital muscles consist of four short muscles connecting the occipital bone to the first two cervical vertebrae, the atlas and the axis. These muscles include the: - rectus capitis posterior major muscles; - rectus capitis posterior minor muscles; - obliquus capitis inferior muscles; - obliquus capitis superior muscles.
The suboccipital muscles are all innervated by the suboccipital nerve. The three scalene muscles are found forming the floor of the posterior triangle. The anterior and middle scalenes originate from the transverse processes of certain cervical vertebrae and attach to the first rib.
The suboccipital region is actually a pyramid shaped muscle compartment located inferior to the external occipital protuberance and deep to the superior part of the posterior cervical region, underlying the trapezius, sternocleidomastoid, splenius, and semispinalis capitis muscles.
The suboccipital muscles are a group of 4 muscles located in the posterior region of the neck, inferior to the occipital bone. These 4 muscles are the rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis superior, and obliquus capitis inferior (see Image.
The suboccipital muscles are a group of four paired muscles located deep in the suboccipital region of the neck at the base of the occipital bone, which is why the group has such a name.
