The L5 dorsal nerve provides sensory innervation to the skin on the top of the foot and the webspace between the big toe and the second toe. It plays a role in transmitting sensory information such as touch, pressure, and temperature from these areas to the brain.
Dorsal rhizotomy is a surgical procedure that involves cutting some of the sensory nerve fibers in the spinal cord's dorsal roots. This procedure is often used to treat severe cases of spasticity or muscle stiffness in conditions like cerebral palsy. By disrupting the nerve signals responsible for the abnormal muscle contractions, dorsal rhizotomy can help improve motor function and alleviate symptoms.
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
ventral root of a spinal nerve
The nerve supply to the levator scapula muscle is from the dorsal scapular nerve (C5) and the third and fourth cervical nerves (C3, C4) that form the cervical plexus.
The medical term for surgical resection of the dorsal root of a spinal nerve to relieve pain is rhizotomy.
Yes
Yes this can happen when any nerve is damaged but this is a greater danger if its an actual Spinal Nerve.

Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
Nerve root clumping is usually indicative of arachnoiditis, a painful, progressive spinal condition. Please research arachnoiditis.
Pinching of the L5 nerve causes weakness in the big toe and ankle and pain on the top of the foot that may extend up to the buttocks.
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
ventral root of a spinal nerve
Yes.
frontal lobe
yes
Yes, the ventral root of a spinal nerve is the efferent motor root, consists of axons of motor neurons. It joins the dorsal root to form a mixed spinal nerve, which consists of afferent sensory neurons (from the dorsal root) and efferent motor neurons (from the ventral root). Therefore severing the ventral root will result in a loss of motor function for the myotome supplied by that spinal nerve.
