Ganglion - ANSWER cluster of neuronal soma (cell bodied) in the PNS
autonomic nervous system - ANSWER relays motor/sensory info to the
viscera of the body
somatic nervous system - ANSWER relays motor/sensory info to the rest of
the body apart from viscera
cannot divide - ANSWER why can't neurons be replaced if destroyed?
unipolar - ANSWER which neuron has peripheral and central processes?
axosomatic, axodendritic, axoaxonic - ANSWER what are the 3 types of
synapses?
ATP is required for exocytosis - ANSWER why are mitochondria located near
the terminal boutons of neurons?
Astrocytes - ANSWER increase neurotransmitter reuptake, increase blood
flow to active brain, controls ionic environment around neurons
microglial cells - ANSWER smallest and least abundant neuroglia.
macrophages of CNS
ependymal cells - ANSWER simple, ciliated epithelium. forms permeable
lining of ventricles. circulates CSF.
Oligodendrocytes - ANSWER myelin-forming cells that help electrically
insulate CNS axons. enlarged foot processes wrap around foot of axon,
,nodes of ranvier present
satellite cells - ANSWER found in PNS and cover plasma membrane in
unipolar, sensory neurons
Schwann cells - ANSWER found in PNS. cover plasma membrane but do not
have processes and one cell wraps around one axon
Neurolemma - ANSWER cytoplasmic contents pushed to outer layer of
schwann cells creating a super thick outer layer
axonal regeneration - ANSWER why is the neurolemma so important?
PNS - ANSWER can axonal regeneration occur is CNS, PNS, or both?
gray matter - ANSWER centralized, composed of cell bodies of interneurons
and motor neurons, neuroglia
white matter - ANSWER fiber tracts of myelinated & nonmyelinated axons,
neuroglia, and surrounding
Nucleus - ANSWER in gray matter, a cluster of soma with same/similar
function
nerve - ANSWER bundle of axons traveling together in PNS
ganglion - ANSWER cluster of neuronal soma in PNS
tract - ANSWER groups of axons traveling in brain/spinal cord
monosynaptic reflex - ANSWER Reflex pathway with only one synapse
between the sensory and motor neurons (ex: knee-jerk).
polysynaptic reflex - ANSWER at least one interneuron between sensory
neuron and motor neuron
, axon hillock - ANSWER activity at this location of a neuron determines
whether or not an action potential will travel down an axon
myselin sheath - ANSWER the initial segment/trigger zone of an axon does
not have?
peripheral - ANSWER which process (central or peripheral) of a unipolar
neuron acts as a dendrite?
central - ANSWER which process (central or peripheral) of a unipolar neuron
acts as an axon?
Cerebrum - ANSWER largest part of the brain that divides into two
hemispheres
Diencephalon - ANSWER Portion of the brain that forms the middle core and
gives rise to the thalamus, hypothalamus, and epithalamus
Cerebellum - ANSWER Second largest part of the brain that lies behind the
pons. Responsible for motor control and cognitive function.
brain ventricles - ANSWER Spaces within the brain continuous with one
another and to the central central of the spinal cord. They are epithelial tubes
lined with ciliates ependymal cells and circulates the cerebrospinal fluid
anterior horn - ANSWER What ventricular structure of the lateral ventricle
supplies the frontal and parietal lobes with CSF?
posterior horn - ANSWER What ventricular structure of the lateral ventricle
supplies the occipital lobes with CSF?
inferior horn - ANSWER What ventricular structure of the lateral ventricle
supplies the temporal lobes with CSF?
