WSU Anatomy Lecture 2 Exam with
correct answers 100% 2026
neurons - Correct Answer transmit electrical signals
support cells - Correct Answer non-excitable
surround and wrap neurons
action potential - Correct Answer specialized cells that conduct electrical impulses alone the
plasma membrane
lengevity - Correct Answer can live and function for a lifetime
synapses - Correct Answer -site of communication between cells
-elaborate cell junctions
-signals pass across synapse in one direction
nissl bodies - Correct Answer densely packed, flattened sacs of rough ER and free ribosomes
dendrites - Correct Answer -extensively branching from the cell body
-transmit electrical signals toward the cell body
-function as receptive sites
axons - Correct Answer -produce and conduct action potentials
-transmit impulses away from the cell body
axon hillock - Correct Answer initial segment of the axon that generates axon potentials
,terminal branches - Correct Answer part of the axon
axon terminals - Correct Answer axon ends in knobs (end bulbs)
multipolar - Correct Answer more than two processes; usually many dendrites and one axon
bipolar - Correct Answer two processes that extend from opposite sides of the cell body
unipolar - Correct Answer one process that emerges from cell body and divides like an inverted
letter T
neurotransmitters - Correct Answer chemical messengers
presynaptic neuron - Correct Answer conducts signal toward a synapse
postsynaptic neuron - Correct Answer -transmits electrical activity away from a synapse
axodendritic - Correct Answer -between axon terminals of one neuron and dendrites of another
axosomatic - Correct Answer between axons and neuronal cell bodies
axoaxonic - Correct Answer uncommon types of synapses
synaptic vesicles - Correct Answer -membrane-bound sacs containing neurotransmitters
-present in axon terminal
, action potnetials - Correct Answer electrical signals
neuroglia - Correct Answer usually only refers to supporting cells in the CNS
astrocytes - Correct Answer -most abundant glial cell type
-take up and release ions to control the environment around neurons
microglia - Correct Answer -part of the CNS's defense system
-smallest and least abundant
phagocytes - Correct Answer -the macrophages of the CNS
-engulf invading microorangisms and dead nureons
ependymal cells - Correct Answer -help produce cerebral spinal fluid (CSF)
-liine the brain ventricles and central cavity of the spinal cord;bear cilia-help regulate the
cerebrospinal fluid
oliodnederocytes - Correct Answer -have few branches
-wrap their cells processes around axons in CNS
-form the myelin sheaths in the CNS
-one coils around several different axons
satellite cells - Correct Answer surround sensory neuron cell bodies within ganglia of PNS
Schwann cells - Correct Answer -surround axons in the PNS
