Anatomical terms of neuroanatomy

The thoracic spinal nerve 10 (T10) is one of the twelve thoracic spinal nerves that originate from the thoracic region of the spinal cord. It plays a crucial role in the innervation of the thoracic and abdominal regions.

Anatomy

The thoracic spinal nerves are part of the peripheral nervous system and emerge from the spinal cord between the thoracic vertebrae. The T10 nerve exits the spinal column below the tenth thoracic vertebra (T10 vertebra). Like other thoracic nerves, T10 is a mixed nerve, containing both sensory and motor fibers.

Branches

The T10 nerve divides into several branches:

• Lateral cutaneous branch: This branch innervates the skin of the lateral thoracic region.
• Anterior cutaneous branch: This branch supplies the skin of the anterior thoracic wall.

Function

The primary function of the T10 nerve is to provide motor innervation to the intercostal muscles, which are responsible for the movement of the rib cage during respiration. Additionally, it provides sensory innervation to the skin overlying the thorax and abdomen.

Clinical Significance

Damage or irritation to the T10 nerve can result in pain, numbness, or weakness in the areas it supplies. Conditions such as herniated discs, spinal stenosis, or trauma can affect the T10 nerve.
