exam 3 nerve tissue, brain Flashcards
(23 cards)
the nervous system is primarily made of
nervous tissue
the central nervous system contains the
brain and spinal cord
what are two components of the sensory nervous system
somatic and visceral
generally the nervous system is made up of ____ cells
2, neurons and glial cells
label neuron components
the neuron cell body houses both the
cytoplasm, and nucleus
the brain and the spinal cord are apart of the
central nervous system
dendrites branch off the
cell body
the functional division of the nervous system that transmits information from the viscera to the central nervous system is the
visceral sensory division
nervous tissue is made up of neurons and
glial cells
the term anaxonic describes a neuron with
no axon
If a sensory neuron detects a painfully hot stimulus, it will send a signal to an interneuron in the CNS for processing. This may result in a motor neuron stimulating muscle contraction, moving the body away from the painful stimulus. What are the structural classifications of the three neurons in this example? (listed in the order they appear)
unipolar, multipolar, multipolar
free and bound ribosomes in a neuron are called either Nissan bodies or
chromatophilic
dendrites transfer information ______ the cell body
toward
which neurons have a single, short neuron process that emerges from the cell body and branches like a t
unipolar
in a lab experiment, a neuron is observed conducting an electrical charge down a long process toward a target cell. what portion of the neuron is being observed
axon
If a(n) Blank______ detects a painful stimulus, it will send a signal to a(n) Blank______ in the CNS for processing. This may result in a(n) Blank______ stimulating muscle contraction, moving the body away from the painful stimulus.
sensory neuron, interneuron, motor neuron
soma is another name for the _____ of a neuron
cell body
bipolar neurons have one axon and _____ dendrite
one
Pseudounipolar is another name for a(n) Blank______ neuron
unipolar
most motor neurons are
multipolar
a nerve fiber is sometimes called
axon
