What nerves are affected by C5 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 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.
What can a C7 spinal cord injury do?
Individuals with a complete C7 spinal cord injury will not be able to move or feel their trunk or lower body, and will also have some impairments in their hands/fingers. This will affect: Bladder and bowel movements. The inability to control these reflexes and muscle contractions can make you very prone to accidents.
What does the C7 nerve control?
The C7 myotome is a group of muscles controlled by the C7 nerve. These muscles include those involved in straightening the elbow, lifting the wrist, elongating the fingers to an outstretched hand, and the triceps muscle in the upper arm.
Can you walk after a C5 spinal cord injury?
Fortunately, it is possible for many SCI survivors. There is potential to walk again after SCI because the spinal cord has the ability to reorganize itself and make adaptive changes called neuroplasticity.
What fingers are affected by C7?
C7 radiculopathy. Tingling, numbness, and/or pain may be felt down the arm and into the middle finger. Weakness may be experienced in the back of the upper arm (triceps).
Can you recover from a C5 injury?
Damage to the C5 spinal cord often results in paralysis of both the upper and lower body, otherwise known as quadriplegia. By participating in rehabilitative therapies, individuals can learn to adjust, cope, and manage the outcomes of their spinal cord injury.
What is a C5 injury?
C5 injury. Person can raise his or her arms and bend elbows. Likely to have some or total paralysis of wrists, hands, trunk and legs. Can speak and use diaphragm, but breathing will be weakened.
What is special about C7?
Unlike the other cervical vertebrae, the C7 has a large spinous process that protrudes posteriorly toward the skin at the back of the neck. This spinous process can be easily seen and felt at the base of the neck, making it a prominent landmark of the skeleton (giving the C7 the name vertebra prominens).
Will I ever walk again with a spinal cord injury?
Approximately 80% of patients with incomplete spinal cord injury (SCI) can regain ambulatory ability after participation in a rehabilitation program. However, most of them can walk non-functionally and require a walking device.
Can C5 C6 cause leg weakness?
An injury to the spinal cord at the C5-C6 level may cause pain, weakness, or paralysis in the arms and/or legs. There may be loss of bowel and bladder control or breathing problems in some cases.
What are symptoms of C5 injury?
Neck pain. This pain is typically felt toward the back or side of the neck.
What are the symptoms of C5 spinal cord injury?
Muscle weakness
What is C5 paralysis?
C5 palsy is a severe complication associated with posterior cervical decompression. The incidence of C5 palsy varies significantly between studies. Excessive spinal cord shifting, preexisting intervertebral foramenal stenosis, OPLL, laminectomy and male gender are risk factors of postoperative C5 palsy.
What is a C5 fracture?
C5 and C6 vertebrae. These vertebrae are each composed of a vertebral body,a vertebral arch,and 2 transverse processes.
