Document Summary
Effectors: organs that are innervated by efferent autonomic nervous. Neuroeffector junction: point of contact between efferent autonomic nerves and cells of the target (effector) organ; analogous to a synapse between neurons. Nerve impulses travel down axon fibers as electrical signals called action potentials. Nerve signals are transmitted from one neuron to another via chemical neurotransmitters at specialized junctions called synapses. Axon: carries the action potential away from the soma. Soma: integrates information received at all the dendrites. Dendrites: receive information from axon terminals of other neurons. Axon hillock: site of action potential formation. Axon terminals: transmit the information to muscle, gland, or other neuron at the synapse. Resting potential: basis for neuronal electric currents, generates and conducts an electrical signal. Every ion has an equilibrium potential that is determined by the relative concentrations of the ion between the two compartments and the charge of the ion.
