What type of neuron typically connects the CNS to effectors in a reflex arc?

In a reflex arc, the type of neuron typically connecting the central nervous system (CNS) to effectors is known as a motor neuron, which is a specific function of somatic motor neurons that may include postganglionic neurons for autonomic effects. These neurons transmit signals from the CNS to muscles or glands, facilitating an immediate response to a stimulus without the need for conscious thought.

While preganglionic and postganglionic neurons are part of the autonomic nervous system and play roles in the connection between the CNS and involuntary effectors like glands or smooth muscle, they are not the primary neurons involved in reflex actions that require rapid reaction. Instead, reflex arcs predominantly involve sensory neurons, interneurons (which facilitate communication between sensory and motor neurons), and motor neurons, which directly innervate the muscles to produce a response.

In this context, the correct focus should be on the role of motor neurons that transmit impulses to effectors to carry out a reflex action, rather than on the classification of preganglionic and postganglionic neurons that serve distinct functions in the autonomic nervous system's pathways.
