True or false: Neurons do not physically touch one another.
Neurons do not physically touch. They are separated by synapses.
Describe the function and release of neurotransmitters.
Neurotransmitters are synthesized in the cell body and stored into secretory vessels in the axon
terminals. they are then released from the presynaptic into the synapse, then the postsynaptic
then they bind on to the dendrites of the receiving neuron.
Neurotransmitters are chemicals stored inside secretory vesicles (axon terminal vesicles) at the
end of the axon terminals.
When neurotransmitters are released by the axon terminal vesicles, they carry the transmission
of the nerve impulse from one neuron to another.
An afferent neuron carries information:
From the central to the peripheral nervous system
From the peripheral to the central nervous system
Within the central nervous system
Within the peripheral nervous system
