Receives stimuli
Receptive region
Plasma membrane exhibits voltage-gated Ca2+ channels.
Secretory region
Plasma membrane exhibits chemically gated ion channels
Receptive region
Area where nerve impulse is generated
Trigger zone
Axon terminals release neurotransmitters.
Secretory zone
Plasma membrane exhibits voltage-gated Na+ and K+ channels.
Conducting zone
One incoming fiber triggers responses in ever-increasing numbers farther and farther along the circuit.
Diverging circuit
May be involved in complex, exacting types of mental processing.
Parallel after-discharge circuit
Involved in control rhythmic activities such as breathing.
Reverberating circuit
Involved in activating fibers of a skeletal muscle such as the bicep muscle.
Diverging circuit
Different types of sensory input can have the same ultimate effect.
