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
