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

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
Explain why the dorsal root ganglions are larger in diameter than the dorsal root?
Dorsal root ganglions are larger in diameter than the dorsal root itself because they have axons on them. Dorsal root ganglions are also called spinal ganglions.
Cell bodies of sensory neurons are found where?
Dorsal root ganglia of the spinal chord gray matter.
What causes the bulge in the dorsal root ganglion?
Melon.
What is the difference between a taproot and a fibrous root and a main root?
What Is The Difference Between TapRoot And Fibrous Root? Tap rootgives the support to the plant and fibrous rootsearch the water and mineral salts in the ground. A main root is a tap root.
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
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
Explain why the dorsal root ganglions are larger in diameter than the dorsal root?
Dorsal root ganglions are larger in diameter than the dorsal root itself because they have axons on them. Dorsal root ganglions are also called spinal ganglions.
Where are large groups of neuron cell bodies found?
In the dorsal root ganglia. The dorsal root ganglia is located in the dorsal root. The cells carry sensory signals to the spinal cord.
Name the structure that is the sensory ganglion of each dorsal root?
Dorsal root ganglion
Cell bodies of sensory neurons are found where?
Dorsal root ganglia of the spinal chord gray matter.
Where do sensory nerve fibers enter the spinal cord?
The dorsal column or medial lemniscus.
What does the dorsal root of the spinal cord carry?
The dorsal root of the spinal nerves carry sensory information to the brain and is hence an afferent pathway.
What is a displaced doral root ganglion?
A dorsal root ganglion is a cluster of nerves in the spine, specifically in the dorsal root. Displaced means that it's been moved out of its intended location.
What does the dorsal root ganglion contain?
Autonomic ganglia contain the cell bodies of motor neurons.
Neuron type in dorsal root ganglion?
sensory
What causes the bulge in the dorsal root ganglion?
Melon.
