Ch 13 Quiz - Part 2

Neuroglia:

• Carry impulses to the spinal cord and to muscles, organs, and glands

• Main body of the neuron

• Act as supporting tissue

• Conduct impulses from one location to another

Nervous system is made up of two tissues (write true or false):

What is the name of the tissues:

• nerves

• neuron fibers

• neuroglia

• neurons

Motor functions:

• efferent processes because they transmit impulses away from the neural cell body to the muscles or organs to be innervated.

• made of axons and dendrites

• act to inhibit the actions of glands and organs

• cause contractions in muscles

Sensory neurons:

• afferent processes because they carry impulses from the sensory receptors to the synaptic endings in the central nervous system.

• are attached to sensory receptors and transmit impulses to the CNS

• do not have true dendrites.

• all of the above

Interneurons:

• called associative nerves

• called central nervers

• located within CNS

• function to mediate impulses between sensory and motor neurons.

PNS consist of two types of sheaths (write true or false):

What are nerves:

• is a collection of nerve fibers

• responsible for efferent processes

• located outside of CNS

• responsible for afferent processes
