The costotransverse joint is the joint formed between the facet of the tubercle of the rib and the adjacent transverse process of a thoracic vertebra.The costotransverse joint is a plane type of synovial joint which, under physiological conditions, allows only gliding movement.
Next, thrust in an inward and upward motion on the diaphragm. This will force air out of the lungs and remove the blockage. Repeat these abdominal thrusts up to five times, the doctor advised.
It supplies a twig to this muscle, receives a communicating filament from the posterior division of the first cervical, and then divides into a large medial and a small lateral branch. The medial branch (ramus medialis; internal branch), called from its size and distribution the greater occipital nerve, ascends obliquely between the Obliquus ...
The greater occipital nerve is a nerve of the head. It is a spinal nerve, specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2.It arises from between the first and second cervical vertebrae, ascends, and then passes through the semispinalis muscle.
For example, the facet joint between T1 and T2 is innervated by C8 and T1 medial branch nerves. Facet joint between L1 and L2; the T12 and L1 medial branch nerves. However, the L5 and S1 facet joint is innervated by the L4 medial branch nerve and the L5 dorsal ramus. In this case, there is no L5 medial branch to innervate the facet joint.
inferior cervical ganglion. The inferior ganglion may be fused with the first thoracic ganglion to form a single structure, the stellate ganglion. – adjacent to C7; target: heart, lower neck, arm, posterior cranial arteries; Nerves emerging from cervical sympathetic ganglia contribute to the cardiac plexus, among other things.
The middle cervical ganglion is the smallest of the three cervical sympathetic ganglia (i.e. of the cervical portion of the sympathetic trunk). [1] It presumably represents the merging of the sympathetic ganglia of cervical segments C5–C6. It is usually situated at the level of the sixth cervical vertebra.
While under the trapezius, the medial branch of the posterior division of the third cervical nerve gives off a branch called the third occipital nerve (also known as the least occipital nerve), which pierces the Trapezius and ends in the skin of the lower part of the back of the head.
