The vertebral foramen is the large opening posterior to the vertebral body also known as the spinal canal. It contains and protects the spinal cord at the thoracic level. The spinous process is long, triangular on coronal section, directed obliquely downward, arising from the lamina and ending in a tuberculated extremity. These processes ...
The thoracic spinal nerve 10 (T10) is a spinal nerve of the thoracic segment. [1] It originates from the spinal column from below the thoracic vertebra 10 (T10).
As the spinal cord terminates at the L1–L2 level, other segments of the spinal cord would be positioned superior to their corresponding bony vertebral body. For example, the T11 spinal segment is located higher than the T11 bony vertebra, and the sacral spinal cord segment is higher than the L1 vertebral body. [7]
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 ...
The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. [1] [2] The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum, and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation.
The lesser splanchnic nerve travels from the vertebral levels T10-T11 to the abdomen's superior mesenteric ganglia, which innervates the superior mesenteric artery, and to the aorticorenal ganglion. [5] The least, or lowest, splanchnic nerve connects the T12 level to the renal plexus. [11]
T9–T10 T10–T12 T10–T11 [3] The lesser splanchnic nerve travels inferiorly, lateral to the greater splanchnic nerve. Its fibers synapse with their postganglionic counterparts in the superior mesenteric ganglion, or in the aorticorenal ganglion. [4] The lesser splanchnic nerve modulates the activity of the enteric nervous system of the midgut.
