The thoracic spinal nerve 6 (T6) is a spinal nerve of the thoracic segment. [1] It originates from the spinal column from below the thoracic vertebra 6 (T6). References
The most common location is the midthoracic vertebrae, especially the eighth (T8). [6] Neurologic signs result from severe angulation of the spine, narrowing of the spinal canal, instability of the spine, and luxation or fracture of the vertebrae. Signs include rear limb weakness or paralysis, urinary or fecal incontinence, and spinal pain. [5]
Tarlov cysts are most commonly located in the S1 to S4/S5 region of the spinal canal, but can be found along any region of the spine.They usually form on the extradural components of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots and arise between the endoneurium and perineurium.

Autonomic dysreflexia (AD) is a potentially fatal medical emergency classically characterized by uncontrolled hypertension and cardiac arrhythmia. [2] [3] [4] AD occurs most often in individuals with spinal cord injuries with lesions at or above the T6 spinal cord level, although it has been reported in patients with lesions as low as T10. [5]
Neurogenic shock results from damage to the spinal cord above the level of the 6th thoracic vertebra. [5] It is found in about half of people who have a spinal cord injury within the first 24 hours, and usually persists for one to three weeks. [5] Neurogenic shock may be caused by severe brain injury. [6]
Some referred pain due to visceral sensations refer to dermatomes that send fibers to the same level of spinal cord. A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root ...
It is most usually observed in the part of the spinal cord corresponding to the neck area. Symptoms are due to spinal cord damage and include pain, decreased sensation of touch, weakness, and loss of muscle tissue. The diagnosis is confirmed with a spinal CT, myelogram or MRI of the spinal cord. The cavity may be reduced by surgical ...
Postoperative radiation is delivered within 2–3 weeks of surgical decompression. Emergency radiation therapy (usually 20 grays in 5 fractions, 30 grays in 10 fractions or 8 grays in 1 fraction) is the mainstay of treatment for malignant spinal cord compression. It is very effective as pain control and local disease control.
