Question

Quizplus · Accepted Answer

Afferent neurons transmit information from sensory receptors to the central nervous system (CNS). In this case, the neurons responsible for sending the signal regarding the painful heat sensation would be afferent neurons. Efferent neurons transmit information from the CNS to muscles and glands, parasympathetic neurons are a type of autonomic nervous system neuron, and somatic neurons control voluntary movements of skeletal muscles. None of these types of neurons are responsible for sending signals about pain sensations.
