ANATOMY

Detailed explanation-1: -Interneurons (also known as association neurons) are neurons that are found exclusively in the central nervous system. ie Found in the brain and spinal cord and not in the peripheral segments of the nervous system.

Detailed explanation-2: -The integration of reflex arcs happens in the spinal cord rather than in the brain, allowing reflexes to occur quickly and without conscious thought. Afferent sensory neurons receive sensory input and transmit the signal on toward the integration center.

Detailed explanation-3: -Types of Neurons: A basic neural pathway involves a sensory neuron sending information to the integration center like the brain, which sends motor information down a motor neuron.

Detailed explanation-4: -The integrating center consists of one or more interneurons, CNS neurons that relay the signal from sensory to motor neurons. Reflex signal carried to skeletal muscle; voluntary.

Detailed explanation-5: -The integration center involves one synapse (monosynaptic reflex arc) or two or more synapses (polysynaptic reflex arc) in the gray matter of the spinal cord. In polysynaptic reflex arcs, one or more interneurons in the gray matter constitute the integration center.
