meningeal branch
spinal nerve
They are situated on the dorsal root of each spinal nerve. (:
Nerve roots exit the spinal cord, and form peripheral nerves to different areas of the body. If i understand what your trying to ask the answer is a dorasal ramus (pl rami)
False
The tibial nerve arises from the L4 to S3 spinal nerve roots. It is a branch of the sciatic nerve and provides motor and sensory innervation to the posterior leg and sole of the foot.
Spinal Accessory Nerve
Olfactory nerve, Optic nerve, Nasal sack, Trigeminal nerve, Gasserian ganglion, Facial nerve, Auditory nerve, Tympanic membrane, Glossopharyngeal nerve, pneumogastric nerve, First spinal nerve, Branchial enlargement, Branchial nerve, Third spinal nerve, fourth spinal nerve, fifth spinal nerve, sixth spinal nerve, seventh spinal nerve, eighth spinal nerve, ninth spinal nerve, tenth spinal nerve, Femoral nerve, Sciatic nerve, Sympathetic nerve trunk, Lumbar enlargement, Sympathetic ganglia, and Filum terminale.
The branch of the spinal nerve that contains only autonomic fibers is the rami communicantes. These are divided into the white rami communicantes, which carry preganglionic sympathetic fibers to the sympathetic ganglia, and the gray rami communicantes, which carry postganglionic sympathetic fibers back to the spinal nerve. These branches are essential for the autonomic nervous system's regulation of involuntary functions.
nerve plexusesThe spinal nerves emerge from the spinal cord at the brain stem, and between each vertebrae.
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
the spinal nerve sends nerve impulses away from the CNS
