100%
action potential can be generated by virtually all cells of the body because all cells
possess cell membranes - ANSWERfalse, only cells with excitable membranes such
as nervous and muscle cells can generate action potential
Nodes of Ranvier are only found on myelinated, peripheral neural processes -
ANSWERtrue
efferent nerve fibers may be described as motor nerve fibers - ANSWERtrue
a positive feedback cycle is the main force in the generation of graded potentials at
receptor ends - ANSWERfalse, positive feedback occurs after depolarization begins
During depolarization, the inside of the neuron's membrane becomes less negative. -
ANSWERtrue
the obligodendrocytes can myelinate several axons - ANSWERtrue
sensory neurons have long dendrites, while motor neurons have long axons -
ANSWERtrue
a graded potential that is the result of a neurotransmitter released into the synapse
between 2 neurons is called postsynaptic potential - ANSWERtrue
in myelinated axons the voltage gates sodium channels are concentrated at the
nodes of ranvier - ANSWERtrue
the 2 major classes of graded potential are transmitter potential and receptor
potential - ANSWERfalse, they are generator potentials and post synaptic potentials
if bacteria invaded the CNS tissue, microglia would migrate to the area to engulf and
destroy them - ANSWERtrue
myelination of the nerve fibers in the central nervous system is the jo. of the
obligodendrocytes - ANSWERtrue
neurons in the CNS are organized into functional groups - ANSWERtrue
reflexes are rapid, automatic responses to stimuli - ANSWERtrue
large diameter nerve fibers conduct impulses much faster than small diameter fibers
- ANSWERtrue
enkephalins and endorphins are peptides that act morphine - ANSWERtrue
