Exam 12: Fundamentals of the Nervous System and Nervous Tissue

The peripheral nerve fibers that measure the degree of stretch in the biceps brachii muscle and its tendons are classified as

Chemical signals diffuse between neurons at this location.

The somatic motor subdivision of the peripheral nervous system is considered to be an involuntary nervous system.

Neurotransmitters are found packaged inside ________ in the axon terminal.

Chromatophilic bodies are clusters of rough ER and free ribosomes that produce the large amount of proteins needed by a neuron.

Gray matter in the CNS contains all of the following except

The white matter is the site where neuron cell bodies are clustered.

General visceral sensory impulses include pain, temperature, nausea, and hunger.

A monosynaptic reflex arc is an example of

The supporting cells of the nervous system that surround and wrap neurons are derived from embryonic neuroepithelial cells from the ectoderm.

In the region of the spinal cord, the cell bodies of most interneurons lie in

The majority of neurons in the body are

The covering of a fascicle within a nerve is the

The ________ of a presynaptic neuron associates with the dendrite of a postsynaptic neuron.

This part of the neuron may have branching collaterals.

Oligodendrocytes and Schwann cells myelinate neurons within the peripheral nervous system.
