Exam 12: Fundamentals of the Nervous System and Nervous Tissue

Figure 12.2 Use the diagrams above to answer the following questions. -Identify which diagram represents a cell that produces a myelin sheath in the central nervous system.

Nonmyelinated axons

The chemical substance that is released at axon terminals is called a

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

An axosomatic synapse occurs between the axon terminals of one neuron and the of a proximal neuron.

All of the neuronʹs organelles are localized to the cell body.

Gray matter in the CNS contains all of the following except

Most synapses transmit communicating signals using

Describe the myelin sheath.

White matter represents

neurons develop from neural crest cells.

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

Most neurons in the body are multipolar neurons.

Neurotransmitters are found packaged inside in the axon terminal.

An example of proprioception is

Ciliated neuroglial cells that form an epithelium and play an active role in forming and moving cerebrospinal fluid are

Figure 12.2 Use the diagrams above to answer the following questions. -Identify which letter represents the most abundant category of glial cells in the CNS.

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

Cytoplasm, organelles, and neurotransmitters move through the cytoplasm of the axon by a mechanism called .

These regions of a neuron are characterized by numerous, short cytoplasmic extensions and are often referred to as receiving regions.
