Spinal Nerve Innervation Chart

Spinal Nerve Innervation Chart - It carries visceral motor, somatic motor, and somatic sensory information to and from the skin and muscles of the back (epaxial muscles). Eg the t4 nerve root runs between the t4 vertebra and t5 vertebra. A dermatome is an area of skin supplied by a single spinal nerve. Web this is a list of muscle innervations grouped by nerves and includes the spinal nerve roots that contribute to the innervation of each muscle. Web there are 31 bilateral pairs of spinal nerves, named from the vertebra they correspond to. Each of these nerves branches out from the spinal cord, dividing and subdividing to form a network connecting the spinal cord to every part of the body. Web many nerves come from the spinal cord, pass through foramina (holes) formed by notches of 24 vertebrae in the movable spinal column, and innervate or supply specific areas and parts of the body.2 whenever specific areas or parts of the body are malfunctioning, generalized and/or specific symptoms are possible.3. 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal, named according to their corresponding vertebral levels.
