What is the difference between the dorsal root the ventral root and the dorsal root ganglion?
Ventral root is the ventral portion of spinal cord,there is no ganglion,cell body is of motor types ,cell info goes out of spinal cord of anterior horn. dorsal root is dorsal portion of spinal cord,it posses ganglion,cell body is of sensory types,information goes into spinal cord posterior horn
The dorsal root of a spinal nerve contain what?
axons of sensory neurons
Where does the shingle virus remain?
In the dorsal root ganglion of the spinal cord.
Where do sensory nerve fibers enter the spinal cord?
The dorsal column or medial lemniscus.
Difference between dorsal ramus and dorsal root?
The roots are two split bases of spinal nerves that connect to the spinal cord. The rami are branches of the spinal nerve that form a complex system throughout the body with the two primary ones being the dorsal (posterior) ramus and the anterior ramus. A diagram would look like an x with the two roots coming together from the spinal cord to go through the intervertebral forming a spinal nerve then splitting again immediately after the intervertebral foramen forming the rami of the spinal nerve
Cell bodies of sensory neurons are collected in ganglia in the?
dorsal root of the spinal cord
Sensory neurons enter the spinal cord via what root?
ventral root yo
What order neuron conduct sensory impulses from the brain stem and spinal cord to the thalamus?
from spinal nerve to posterior (dorsal) root
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
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).
Where are large groups of neuron cell bodies found?
Large groups of neuron cell bodies are found in structures called ganglia in the peripheral nervous system and nuclei in the central nervous system. Ganglia are clusters of cell bodies outside the brain and spinal cord, whereas nuclei are centralized collections of cell bodies within the brain.
Cell body for first order neuron located here?
The cell body of the first-order neuron is typically located in the dorsal root ganglion (also known as the spinal or sensory ganglion) of the spinal cord. From there, it sends signals to the spinal cord or directly to the brain, depending on the type of sensory information it is transmitting.
