What nerves do C7 affect?
The nerve root of C7 runs between vertebrae C6 and C7. Motor function includes: full shoulder movement (rotation, adduction and abduction) strong scapular stability….Tricep:
- assess ability to straighten bent elbow against resistance.
- assess ability to straighten elbow against examiner resistance.
- C7 tricep function.
What muscles are innervated by C7 nerve root?
C7 mainly forms the radial nerve to innervate triceps muscle; d. C8 mainly forms the median nerve to innervate the flexor digitorum muscle; e. T1 mainly forms the ulnar nerve to innervate the intrinsic muscles of the hand.
What does C7 supply?
Cords. 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.
What does the C2 vertebra control?
What is a C2 Vertebra? The C2 vertebra is the axis which the C1 vertebra pivots around and lets us move our skulls from side to side in a horizontal motion. Like the C1 vertebra, a C2 vertebra has a greater degree of motion than other vertebrae that are lower on the spinal column.
What muscles attach C2?
- attached to the anterior surface of the vertebral body. longus colli.
- attached to transverse processes. levator scapulae. scalenus medius. splenius cervicis.
- attached to spinous processes. semispinalis cervicis. rectus capitis posterior major.
- attached to posterior surface of lamina. multifidus and longissimus.
How do you treat a pinched nerve C7?
Other pinched nerve treatments
- soft cervical collar.
- hot or cold compress.
- practicing good posture.
- nonsteroidal anti-inflammatory drugs (NSAIDs)
What are the muscles controlled by the C7 nerve?
This dermatome includes areas of skin covering the shoulders, back of the arms, and the middle finger. 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.
What happens when the C7 nerve is compressed?
When the C7 nerve is compressed or irritated, additional complaints may follow, such as: See What Is Cervical Radiculopathy? When the spinal cord gets injured at C6-C7, pain, weakness, or paralysis may occur in one or more parts of the body below the injured level. Reduction of bowel, bladder, and/or breathing functions may occur in some cases.
How does the C6 and C7 vertebrae protect the spinal cord?
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. The C6 and C7 vertebrae help protect the spinal cord within the spinal canal.
Where does the C8 nerve exit the cervical spine?
Although C8 does not have a vertebra, the nerve extends from the C7 vertebrae and exits out between C7 and T1 vertebrae from a small opening called the intervertebral foramen. What Causes Cervical Spinal Injuries?
