HUBS 191 progress test 2 UPDATED
ACTUAL Questions and CORRECT
Answers
central nervous system - CORRECT ANSWER- ✔✔nervous system consisting of brain and
spinal cord
peripheral nervous system - CORRECT ANSWER- ✔✔nervous system consisting of
peripheral nerves
glia - CORRECT ANSWER- ✔✔'glue' provide support for neurons, 5 type, 4 in CNS, 1 in
PNS
neurons - CORRECT ANSWER- ✔✔nerve cells, transmission of information
dendrites - CORRECT ANSWER- ✔✔recieve input, send info into cell body
cell body - CORRECT ANSWER- ✔✔contains nucleus and organelles
axon - CORRECT ANSWER- ✔✔carries electrical impulses, may/may not be myelinated
axon terminals - CORRECT ANSWER- ✔✔end terminus of the axon, neuro transmitter
release
tract - CORRECT ANSWER- ✔✔bundle of axons in the CNS
grey matter - CORRECT ANSWER- ✔✔group of cell bodies in cerebral cortex/spinal cord
white matter - CORRECT ANSWER- ✔✔bundle of axons in cerebral cortex/spinal cord
,ganglion - CORRECT ANSWER- ✔✔group of cell bodies in PNS
nerve - CORRECT ANSWER- ✔✔bundle of axons in PNS
input zone - CORRECT ANSWER- ✔✔dendrites and cell body, receives chemical signals
from other neurons
summation zone - CORRECT ANSWER- ✔✔axon hillock, decides to transmit signal or not
conduction zone - CORRECT ANSWER- ✔✔axon may be quite long, carry electrical signals
between brain areas to and from spinal cord or to and from peripheral sensory receptors
output zone - CORRECT ANSWER- ✔✔axon terminals, contact input of other neurons,
release of neuro transmitter
multipolar - CORRECT ANSWER- ✔✔multiple processes emanate from the cell body, the
'typical' neuron
bipolar - CORRECT ANSWER- ✔✔2 processes emanate from the cell body (axon and long
bridge to dendrites
unipolar - CORRECT ANSWER- ✔✔1 process emanates from cell body (hangs on side of
axon)
microglia - CORRECT ANSWER- ✔✔immune cells of the CNS, engulf micro organisms /
debris
, ependymal cells - CORRECT ANSWER- ✔✔line fluid filled spaces of brain and spinal cord,
have cillia to circulate CSF, CNS
oligodentrocytes - CORRECT ANSWER- ✔✔support nerve fibres, ensheath them with
myelin, CNS
schwann cells - CORRECT ANSWER- ✔✔support peripheral nerve fibres, ensheath them
with myelin, similar to oligodendrocytes, PNS
myelin sheath - CORRECT ANSWER- ✔✔lipid wrapped around axon, increases conduction
velocity, multiple schwann cells in a row form the myelin sheath, gaps between myelin called
nodes of ranivier
Synapse/Synpatic Cleft - CORRECT ANSWER- ✔✔neuro transmitter release from one axon
terminals where electrical turns to chemical
afferent - CORRECT ANSWER- ✔✔information going into the brain
efferent - CORRECT ANSWER- ✔✔information out of brain
flow of information - CORRECT ANSWER- ✔✔info comes through receptors, afferent
nerves, into CNS, integration/coordination, motor efferent (somatic or autonomic)
somatic - CORRECT ANSWER- ✔✔the stuff we are aware of and have control over
somatic afferent - CORRECT ANSWER- ✔✔sensory information of what we are aware of
somatic efferent - CORRECT ANSWER- ✔✔voluntary muscle control, 2 neurons between
brain and effector, upper and lower motor neuron
upper motor neuron - CORRECT ANSWER- ✔✔cell body in brain, axon in spinal cord
