Question

question 24
what term describes the bundles of nerve fibers within the central nervous system?
fascicles
tracts
perineurium
synapse

question 25
bundles of myelinated fibers make up the
gray matter of the nervous system.
ganglia.
white matter of the nervous system.
motor nerves.

question 26
chemical signals diffuse between neurons at this location.
synapse
axon terminal
axon
cell body
dendrite

Explanation:

• Question 24: In the central nervous system, bundles of nerve - fibers are called tracts. Fascicles are in peripheral nerves, perineurium is a connective - tissue layer around fascicles, and synapse is the junction between neurons.
• Question 25: Myelinated fibers make up the white matter of the nervous system. Gray matter consists of cell bodies, ganglia are collections of cell bodies outside the CNS, and motor nerves are a type of nerve carrying motor signals.
• Question 26: Chemical signals diffuse between neurons at the synapse. Axon terminal is part of the axon where neurotransmitters are released, axon is the long part of a neuron for signal conduction, cell body contains the nucleus, and dendrite receives signals.

Answer:

Question 24: B. tracts
Question 25: C. white matter of the nervous system
Question 26: A. synapse
