What nerves are affected by C5 C6 and C7?

From the lateral cord, C5, C6, and C7 supply the pectoralis major and minor muscles, via the lateral and medial pectoral nerves, as well as the coracobrachialis, brachialis and biceps brachii, via the musculocutaneous nerve. The musculocutaneous nerve provides sensation to the skin of the lateral forearm.

What is HNP of cervical spine?

Herniation of the nucleus pulposus (HNP) at the cervical level often results in radiculopathy, marked by compression and inflammation of the cervical nerve root near the neural foramen. Cervical HNP can be generally classified into four types: disc bulge, protrusion, extrusion, and sequestration [1].

What does C5 C6/C7 mean?

The C5-C6 spinal motion segment (located in the lower cervical spine just above the C7 vertebra) provides flexibility and support to much of the neck and the head above.

What can cause c4 5 C5 6 C6 7 herniated discs?

What causes a C5-C6 disc herniation? The most common cause of a herniated disc is an injury or trauma, such as from an auto accident or work comp injury. Whether it be from a car accident, lifting something heavy, a sports-related injury, or something else entirely, this condition can be very painful and bothersome.

What does C5 through C7 control?

C5 provides sensation to the upper part of your upper arm down to your elbow. Cervical nerve 6 controls the extensor muscles of your wrist and is involved in the control of your biceps. C6 provides sensation to the thumb side of your forearm and hand. Cervical nerve 7 controls your triceps and wrist extensor muscles.

Is herniated nucleus pulposus serious?

Complications associated with nucleus pulposus herniation can result from the compression effect on the nerve root in severe cases resulting in motor deficit, in the cervical and thoracic spine there is also a risk of spinal cord compression in severe cases.

What does HNP stand for?

Overview. Herniated nucleus pulposus is a condition in which part or all of the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of the disk, resulting in back pain and nerve root irritation.

Where is C5 6 and C6 7 located?

cervical spine
The C5 C6 spinal motion segment is located in the lower portion of the cervical spine and consists of C5 and C6 vertebrae, and the anatomical structures connecting them. This segment helps provide neck flexibility, supports the upper cervical spine and head, and protects the spinal cord and nerve pathways.

Is a herniated disc life threatening?

With proper treatment, usually a combination of pain medication and physical therapy, disc herniation symptoms can resolve within four to six weeks. Herniated disc is not life threatening, but in some cases it can lead to nerve damage that can be permanently debilitating.
