Spinalnervs
Spinalnervs refer to the paired mixed nerves that emerge from the spinal cord, forming part of the peripheral nervous system. Each spinalnerv is formed by the dorsal root, which carries sensory information to the spinal cord and contains a dorsal root ganglion, and the ventral root, which transmits motor signals from the spinal cord to skeletal muscles. The two roots join to form a single mixed spinal nerve shortly after exiting the spinal column.
In humans there are 31 pairs of spinalnervs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and
Functionally, spinalnervs carry somatic sensory information from the skin, muscles, and joints and provide motor commands
Clinical relevance includes radiculopathy from nerve compression or inflammation, such as might occur with herniated discs
Developmentally, spinalnervs arise from the neural tube and neural crest during embryogenesis. The dorsal root ganglia
