Question

bio1130 exam 3 - chapters 10 and 11 nervous syst... what is contained in the dorsal root ganglia? multiple choice cells bodies of sensory neurons cerebrospinal fluid axons of motor neurons axons of postganglionic neurons

Explanation:

Dorsal root ganglia (also called spinal ganglia) are clusters of nerve cell bodies (neuron cell bodies) associated with the dorsal roots of the spinal nerves. These cell bodies belong to sensory neurons. Sensory neurons carry sensory information (like touch, pain, temperature from the periphery) toward the central nervous system. Cerebrospinal fluid is in the subarachnoid space, ventricles etc., not in dorsal root ganglia. Axons of motor neurons are in ventral roots, and axons of postganglionic neurons (in autonomic system) are not the main component of dorsal root ganglia. So the correct component of dorsal root ganglia is the cell bodies of sensory neurons.

Answer:

A. Cell bodies of sensory neurons
