TRUE/FALSE BIO CH 9

True

A neuron is also known as the "conducting" cell of the nervous system

True

A neuron's cell body is also known as its soma

True?

A polarized cell membrane arises from an unequal distribution of positive and negative ions between sides of the membrane.

False

An afferent process takes place when impulses are carried away from the cell body

True

In multipolar neurons only one process of each neuron is an axon; the rest are dendrites

True

Major organs of the CNS are the brain and the spinal cord.

True

Neuroglia is a term that means "nerve glue"

True?

Neurons do not undergo mitosis.

False

The autonomic nervous system is divided into the central nervous system and the peripheral nervous system.

True

The cell bodies of bipolar neurons have only two processes

False

The efferent or motor division transmits impulses from peripheral organs to the central nervous system.

false

The function of the autonomic nervous system is to supply motor impulses only to cardiac muscle.

True

The nervous system has two subdivisions: The CNS and the PNS

False

The neuroglia cell is the structural unit of the nervous system.

True

The peripheral nervous system consists of an afferent and an efferent division.

true

There are only 2 main types of cells in nerve tissue: the neuron and the neuroglia cell.

True

Axons are designed to carry impulses away from the cell body

False

Efferent processes take place when impulses are transmitted to the cell body

True

Unipolar neurons have single process which is divided into two branches: a peripheral process and a central process.

True

most sensory neurons are unipolar
