List and define the four types of neuronal circuits in the nervous system. What is the function of each?

Diverging circuits allow for transmission of nerve impulses from _____ neuron(s) to _____ neuron(s).

The three basic functions of the nervous system are _____ function, _____ function, and _____ function.

The portion of the plasma membrane of a neuron that surrounds the axoplasm is called the axolemma.

A main difference between neurons (nerve cells) and neuroglia (glia) is:

Regeneration of nerve fibers in the central nervous system is highly unlikely because:

Accidentally stepping on a nail with the sole of your foot causes you quite a bit of discomfort. Which type of pathway is involved in relaying information about the nail to the central nervous system?

Select the best description of the Schwann cells (neurolemmocytes):

The efferent (motor) portion of the autonomic nervous system consists of sympathetic and parasympathetic divisions.

Arrange the following terms in a chart that exhibits your understanding of the functional organization of the nervous system: somatic nervous system, central nervous system, sympathetic division, peripheral nervous system, parasympathetic division, autonomic nervous system.

White matter includes:

When compared to unmyelinated axons, myelinated axons: 1) are electrically insulated 2) are gray in color 3) have a faster speed of nerve impulse conduction 4) are more numerous

The peripheral nervous system includes:

Dendrites are processes of a neuron that:

_____ (or sensory) impulses travel from the _____ to the _____.

A significant difference between neurons and neuroglia is that mature neuroglia can divide whereas mature neurons generally cannot divide.
