The posterior scalene, (Latin: scalenus posterior) is the smallest and most deeply seated of the scalene muscles. It arises, by two or three separate tendons, from the posterior tubercles of the transverse processes of the lower two or three cervical vertebrae, and is inserted by a thin tendon into the outer surface of the second rib, behind ...
Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...
This bridge originates in the deep layers of the suboccipital muscles, specifically in the rectus capitis posterior minor muscle, and extends to join the dura mater of the cervical spinal cord. This structural connection forms a continuous link from the base of the skull to the top of the cervical spine. Recent studies postulate the existence ...
The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
It surrounds the neck like a collar, it splits around the sternocleidomastoid muscle and the trapezius muscle. It is attached as; Posteriorly - Ligamentum nuchae; Anteriorly - Attached to the hyoid bone; Superiorly - (from backwards to forwards); External occipital protuberance and superior nuchal line of occipital bone; Mastoid process of ...
The deep cervical vein (posterior vertebral vein or posterior deep cervical vein [citation needed]) is the vena comitans of the deep cervical artery.The vein is formed in the suboccipital region by the convergence of communicating branches of the occipital vein, veins draining the suboccipital muscles, and veins from the venous plexuses that surround cervical nerves.
Those between the posterior tubercles are termed the posterior intertransversarii. Both sets are supplied by the anterior rami of the spinal nerves. There are seven pairs of these muscles, the first pair being between the atlas and axis, and the last pair between the seventh cervical and first thoracic vertebræ.
The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. [1] C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami). It originates from the spinal column from above the cervical vertebra 1 (C1). [2]
