In between C5-C6, the C6 spinal nerve exits the spinal cord through a small bony opening on the left and right sides of the spinal canal called the intervertebral foramen. This C6 nerve has a sensory root and a motor root. The C6 dermatome is an area of skin that receives sensations through the C6 nerve.

2018年4月23日 · Anterior cervical discectomy and fusion (ACDF) surgery involves removing the C5-C6 intervertebral disc to relieve pressure on the spinal cord or C6 nerve root. The disc is replaced by an implant or bone graft, allowing biological fusion …

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: Subclavius Supraspinatus Infraspinatus ...

The C6 nerve root exits the spine at this level, controlling functions in the arms, such as wrist extension and some movements of the fingers. When the C5 C6 spine is affected by degeneration or injury, it can lead to significant discomfort, weakness, or even neurological issues.

Compression of roots C5 (2–6.6%). One possible explanation is that intervertebral foramina are largest in the upper cervical region and progressively decrease in size in the middle and lower cervical areas, with an exception of the C7-Th1 foramen (C8).

2024年9月5日 · Cervical radiculopathy is a clinical condition characterized by unilateral arm pain, numbness and tingling in a dermatomal distribution in the hand, and weakness in specific muscle groups associated with a single cervical nerve root.

2023年11月8日 · At the C5 level, nerve roots emerge from the spinal cord, forming a part of the brachial plexus — a complex network of nerves governing movement and sensation in the arms and hands. Underneath the C6, the sixth cervical vertebra features a vertebral body, vertebral arch and associated processes that provide structural support to the spine.

2023年7月24日 · Additionally, from C5 and C6, the axillary nerve supplies the motor function of the deltoid and teres minor, as well as the sensory aspect of the overlying skin, the superior lateral cutaneous nerve of the arm, and the skin of the lateral shoulder and arm.

2022年3月29日 · Cervical radiculopathy (also known as “pinched nerve”) is a condition that results in radiating pain, weakness and/or numbness caused by compression of any of the nerve roots in your neck. Most cases of cervical radiculopathy go away with nonsurgical treatment.

Each level of the cervical spine has four nerve roots—two on each side—that branch off from the spinal cord. The two types of nerve roots on each side include: The ventral root and dorsal root branch off separately from the spinal cord then merge together in the intervertebral foramen, a small bony opening between the two adjacent vertebrae.
