Question

Quizplus · Accepted Answer

A spinal reflex is composed of a single sensory neuron and a single motor neuron, which work together to produce a rapid, automatic response to a stimulus without requiring input from the brain. This allows for quick reactions to potentially harmful stimuli, such as pulling one's hand away from a hot stove before feeling the pain. Agonist molecules, endocrine pathways, and homeostatic responses involve more complex physiological processes and do not specifically involve only a single sensory and motor neuron.
