Rio Salado Bio 201 Exam 3 CORRECT
100%!!
What type of cells can generate action potentials? - ANSWERcells with excitable
membranes
Where are nodes of Ranvier are found? - ANSWERon myelinated, peripheral neural
processes
postsynaptic potential - ANSWERA graded potential that is the result of a
neurotransmitter released into the synapse between two neurons
The two major classes of graded potentials - ANSWERgenerator potentials and post-
synaptic potentials
Reflexes - ANSWERrapid, automatic responses to stimuli
Saltatory conduction - ANSWERthe signal jumping from node to node along the
axon
facilitated zone - ANSWERNeurons that are far away from the center of the neuron
pool and thata re not easily excited by an incoming stimulus
axosomatic synapse - ANSWERA synapse formed between the axonal ending of
one neuron and the cell body of another neuron
all-or-non phenomenon - ANSWERthe action potential either happens completely or
it doesn't happen at all
motor division of the PNS - ANSWERsubdivided into two main parts: the somatic
nervous system (also known as the voluntary nervous system because it allows the
human body to consciously control its skeletal muscles), and the autonomic nervous
system (also known as the involuntary nervous system because it regulates activities
beyond conscious control such as smooth muscles, cardiac muscles, and glands)
autonomic nervous system - ANSWERsubdivided into two main parts: the
sympathetic nervous system (which mobilizes body systems during activity), and the
parasympathetic nervous system (which conserves energy, and promotes
maintenance activities during times of rest)
peripheral nervous system (PNS) - ANSWERsubdivided into two parts: the sensory
or afferent division (carrying sensory impulses to the CNS), and the motor or efferent
division (carrying impulses from the CNS to muscles and glands)
supporting cells of nervous tissue - ANSWERsmaller cells that surround and wrap
the neurons
