Question

Quizplus · Accepted Answer

The ejaculation of semen is a polysynaptic reflex because it involves multiple synapses between sensory neurons, interneurons, and motor neurons. The stimulus of sexual arousal is received by sensory neurons, which synapse with interneurons in the spinal cord, which then activate motor neurons that cause contraction of muscles involved in ejaculation. The patellar reflex, postural reflexes, adjustments that steady a limb during a constant load, and the GTO reflex are all examples of monosynaptic reflexes, which involve only one synapse between sensory and motor neurons.
