What is Dorsal rhizotomy?
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.
All chordates have dorsal tubular nerve cords?
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
What is the nerve supply to the levator scapula?
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.
What is the medical term meaning surgical resection of the dorsal root of a spinal nerve to relieve pain?
The medical term for surgical resection of the dorsal root of a spinal nerve to relieve pain is rhizotomy.
Does a kangaroo have a dorsal nerve cord notochord?
Yes
Would there be a loss of sensory or motor function when someone damages the dorsal root of a spinal nerve?
Yes this can happen when any nerve is damaged but this is a greater danger if its an actual Spinal Nerve.

Does a kangaroo have a dorsal nerve cord?
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
What is Nerve root clumping at L4 L5 and L5 S1?
Nerve root clumping is usually indicative of arachnoiditis, a painful, progressive spinal condition. Please research arachnoiditis.
Where is pain felt when a L5 nerve is pinched?
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.
All chordates have dorsal tubular nerve cords?
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
Does bullfrog have a dorsal nerve cord?
Yes.
What is dorsal to the optic nerve?
frontal lobe
Does salmon have dorsal nerve chords?
yes
Is ventral root a loss of motor function?
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.
