The posterior cutaneous nerve of forearm is a nerve found in humans and other animals. It is also known as the dorsal antebrachial cutaneous nerve, the external cutaneous branch of the musculospiral nerve, and the posterior antebrachial cutaneous nerve. It is a cutaneous nerve (a nerve that supplies skin) of the forearm.
The dorsal ramus of spinal nerve, posterior ramus of spinal nerve, or posterior primary division is the posterior division of a spinal nerve. The dorsal rami provide motor innervation to the deep (a.k.a. intrinsic or true) muscles of the back, and sensory innervation to the skin of the posterior portion of the head, neck and back. [1]
The medial cutaneous branches of the posterior divisions of the thoracic nerves descend for some distance close to the spinous processes before reaching the skin, while the lateral branches travel downward for a considerable distance—it may be as much as the breadth of four ribs—before they become superficial; the branch from the twelfth thoracic, for instance, reaches the skin only a ...
The medial clunial nerves innervate the skin of the buttocks closest to the midline of the body. Those nerves arise from the posterior rami of spinal sacral nerves (S1, S2, and S3). Additional images
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 posterior divisions of the sacral nerves are small and diminish in size as they move downward; they emerge, except the last, through the posterior sacral foramina. The upper three are covered at their points of exit by the multifidus and divide into medial and lateral branches.
A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. [1] [2] These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. [1]
Segmental innervation refers to the distribution (innervation) of nerves within an organ or muscle. These nerves are attached to a segment of the spine. [1] Segmental innervation can be mapped through stimulation of the nerve at the spinal segment. [2]
