Cervical Transverse Nerve Root Compression at C3 – C4

Compression of the C3–C4 nerve root, also called cervical transverse nerve root compression at C3-C4, occurs when the spinal nerve root exiting between the third and fourth cervical vertebrae is pinched or irritated. This interference disrupts normal nerve signaling, leading to pain, numbness, or weakness in areas served by these nerves. In a broader sense, this condition falls under cervical radiculopathy, which describes any nerve root compression in the neck PMC.

Anatomy

Structure and Location

The C3 and C4 nerve roots emerge as paired roots from the spinal cord at the levels of the third and fourth cervical vertebrae. They exit via the intervertebral foramina—small openings between vertebrae—and then join nearby roots to form the cervical plexus in the deep neck region NCBI.

Origin

Each C3 and C4 nerve root originates from the corresponding spinal cord segment. They split into a dorsal (sensory) root and a ventral (motor) root before merging into a mixed spinal nerve just outside the vertebral column ScienceDirect.

Insertion

After exiting the spine, the mixed C3–C4 nerves branch into motor fibers that innervate muscles such as the levator scapulae and scalenus medius, and sensory fibers that supply the skin over the lower neck and upper shoulder area TeachMeAnatomy.

Blood Supply

Radicular arteries—small vessels branching from the vertebral, ascending cervical, and deep cervical arteries—accompany the C3–C4 nerve roots through the neural foramina. These vessels provide the essential blood flow that keeps the nerve roots healthy NCBITurkish Neurosurgery.

Nerve Supply

As mixed nerves, C3 and C4 carry their own motor and sensory fibers: motor signals travel to neck muscles, and sensory signals relay touch, pain, and temperature from the skin regions corresponding to their dermatomes TeachMeAnatomyCleveland Clinic.

Functions

1. Sensory Feedback: Conveys touch, pain, and temperature sensations from the lower neck and upper shoulder region Cleveland Clinic.

2. Motor Control: Drives muscles like the levator scapulae and scalenus medius, facilitating head and neck movement TeachMeAnatomy.

3. Diaphragm Support: Contributes fibers to the phrenic nerve (C3–C5), essential for diaphragmatic breathing TeachMeAnatomy.

4. Proprioception: Provides feedback on neck position and movement, aiding balance and posture control TeachMeAnatomy.

5. Spinal Stability: Innervates deep cervical muscles that stabilize the neck during motion TeachMeAnatomy.

6. Pain Signaling: Transmits pain signals from neck structures to the brain, alerting the body to injury or irritation Cleveland Clinic.
