What else can I help you with?
The motor root of the spinal nerve is also referred to as the?
ventral root
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.
What part of the spinal nerve consists of motor fibers leaving the spinal cord?
The ventral root.
What would be the result of damage to ventral root of a spinal nerve?
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
The anterior root and the posterior root fuse to form?
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).
What would happen if the following structures were damaged or transected 1. dorsal root of spinal nerve 2. ventral root of spinal cord 3. ventral ramus of spinal cord?
loss of both the motor and sensory functions
Spinal nerve roots which contain only motor neuron axons?
the what? root of a spinal nerve consists of motor neuron axons
What would happen if the ventral root of a spinal nerve were damaged?
Loss of both motor and sensory function
What is the function of the ventral root of a spinal nerve?
The ventral root of a spinal nerve contains efferent motor neurons that carry signals away from the spinal cord to muscles and glands in the body. These motor neurons control voluntary movements and autonomic functions.
Dorsal and ventral nerves of each spinal nerve unite to form what?
spinal nerve
