Question

Quizplus · Accepted Answer

Autonomic reflexes involve two motor neurons in their pathways. The first neuron is a preganglionic neuron that synapses with a second, postganglionic neuron, which then innervates the target effector organs: cardiac muscle, smooth muscle, or glands. This is in contrast to somatic reflexes, which typically involve a single motor neuron that directly innervates skeletal muscle.
