A ganglion is a nerve cell cluster whose primary function is to act as a junction or relay point in the nervous system between to differing neurological structures. For example, there is a ganglia cluster in the wrist that connects the digital nerves to the brachial nerves and transmits sensory information from the hands to the pathways in the arm.

Name the structure that is the sensory ganglion of each dorsal root?
Dorsal root ganglion
The dorsal root ganglion contains cell bodies of sensory neurons true or false?
A dorsal root ganglion is a nodule on the dorsal root of the spinal cord, and contains the cell bodies of neurons that are afferent. Afferent neurons collect sensory signals from the body and send them to various divisions of the brain.
What type of neuron is found in the dorsal root ganglion?
Sensory. Large diameter sensory neurons populate the medial division of the DRG and convey information regarding proprioception, localized touch, and vibration. In the lateral part of the DRG, small diameter sensory neurons conveying information about pain and temperature.
What does the dorsal root ganglion contain?
Autonomic ganglia contain the cell bodies of motor neurons.
What function type are motor neurons?
motor neurons carry message from inter neurons and transmit it to different parts of the body.
Are there bipolar cells in the ciliary ganglion?
Bipolar neurons in the ciliary ganglion only exist during embryonic development and in vitro. Adult in vivo choroid and ciliary neurons in the ciliary ganglion are all unipolar.
Which type of neurons are sensory neurons?
Sensory neurons traveling through the dorsal root ganglion (DRG) are pseudounipolar neurons.
Where are Multipolar neurons found?
Unipolar neurons are found in ganglion outside the CNS.
What neuron conducts impulses from ganglion?
Post synaptic neurons
Does chain ganglion contain soma from sensory neurons?
false
Name the structure that is the sensory ganglion of each dorsal root?
Dorsal root ganglion
What is the pns cell that surrounds dorsal root ganglion neurons?
Satellite cells
A knot like swelling in a nerve where the cell bodies of neurons are concentrated?
ganglion

Name the PNS glial cell that surrounds dorsal root ganglion neurons?
satellite cell.
What are the differences between preganglionic and postganglionic neurons?
You have a really good question. Studying the nervous system can be overwhelming and quit confusing. Preganglionic Neurons come from the CNS to the Ganglion ( mass of neuron cell bodies and dendrites) and Postganglionic neurons leave the ganglion and head toward the effector organ ( smooth muscle, glands, etc..).
