The Neural Circuitry Underlying the Gill-Withdrawal Reflex Is Known: a Sensory

Multiple Choice

The neural circuitry underlying the gill-withdrawal reflex is known: A sensory neuron in the gill synapses onto a motor neuron that innervates the gill. What is a neural mechanism for habituation?

A) With repeated stimulation, the sensory neuron produces fewer and fewer action potentials.
B) With repeated stimulation, the sensory neuron produces action potentials of decreased amplitude.
C) With repeated stimulation the synaptic response in the motor neuron decreases.
D) With repeated stimulation the motor neuron releases less neurotransmitter.
E) With repeated stimulation the muscles become fatigued.
