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
The dorsal ramus is a branch of the spinal nerve that innervates the muscles and skin along the spine, while the dorsal root is a bundle of nerve fibers that carry sensory information from the body to the spinal cord. The dorsal ramus carries both sensory and motor fibers, while the dorsal root exclusively carries sensory fibers.

What is the difference between the dorsal root the ventral root and the dorsal root ganglion?
The dorsal root is responsible for carrying sensory information from the body to the spinal cord, while the ventral root carries motor information from the spinal cord to the body. The dorsal root ganglion is a structure located on the dorsal root containing cell bodies of sensory neurons.
Explain why the dorsal root ganglions are larger in diameter than the dorsal root?
Dorsal root ganglia contain cell bodies of sensory neurons, which are larger and more complex structures compared to the dorsal root that mainly consists of nerve fibers. The ganglia need more space to accommodate the cell bodies and additional structures like satellite cells and glial cells, leading to their larger diameter compared to the dorsal root.
What causes the bulge in the dorsal root ganglion?
Melon.
What is the difference between tiny root and root hair?
Tiny root is multicellular whereas root hair is unicellular
What is a dorsal root and what type of neuron is found within this structure?
no
What is the difference between the dorsal root the ventral root and the dorsal root ganglion?
The dorsal root is responsible for carrying sensory information from the body to the spinal cord, while the ventral root carries motor information from the spinal cord to the body. The dorsal root ganglion is a structure located on the dorsal root containing cell bodies of sensory neurons.
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
Name the structure that is the sensory ganglion of each dorsal root?
The structure that is the sensory ganglion of each dorsal root is the dorsal root ganglion.
Explain why the dorsal root ganglions are larger in diameter than the dorsal root?
Dorsal root ganglia contain cell bodies of sensory neurons, which are larger and more complex structures compared to the dorsal root that mainly consists of nerve fibers. The ganglia need more space to accommodate the cell bodies and additional structures like satellite cells and glial cells, leading to their larger diameter compared to the dorsal root.
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.
Neuron type in dorsal root ganglion?
sensory
What causes the bulge in the dorsal root ganglion?
Melon.
What is difference between groundnut root and onion root?
tap root and fibers roots
Where are pseudounipolar neurons found?
The soma (cell body) of each pseudounipolar neuron is located within a dorsal root ganglion. The axon leaves the cell body (and out of the dorsal root ganglion) into the dorsal root, where it splits into two branches. The central branch goes to the posterior (dorsal) horn of the spinal cord, where it forms synapses with other neurons. The peripheral branch travels through the distal dorsal root into the spinal nerve all the way until skin, joint, and muscle.
What is the difference between homemade root beer and store bought root beer?
your mom and my grandma. get the difference ;)
