A retrolisthesis is a posterior displacement of one vertebral body with respect to the subjacent vertebra to a degree less than a luxation (dislocation). Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views where care has been taken to expose for a true lateral view without any rotation offer the best diagnostic ...
Spondylolisthesis is when one spinal vertebra slips out of place compared to another. [1] While some medical dictionaries define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum), [2] [3] it is often defined in medical textbooks as displacement in any direction.
The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 6 (C6).. The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm, [2] including:
The cervical spinal nerve 5 (C5) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 5 (C5). It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the ...
The upper surface of each usually has a shallow sulcus for the eighth spinal nerve, and its extremity seldom presents more than a trace of bifurcation. The transverse foramen may be as large as that in the other cervical vertebrae, but it is generally smaller on one or both sides; occasionally, it is double, and sometimes it is absent.
The middle cervical ganglion is presumed to represent the union of the two sympathetic ganglia corresponding to cervical segments C5–C6 since its gray rami communicantes usually join the cervical spinal nerves C5–C6, however, the ganglion sometimes also contributes gray rami communicantes to spinal nerves C4 and C7.

The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
