GENERAL HISTOLOGY

Detailed explanation-1: -Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS. They usually have long dendrites and relatively short axons. Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands.

Detailed explanation-2: -Afferent neurons in the dorsal roots carry impulses from the body’s sensory receptors to the spinal cord, where the information begins to be processed. The ventral horns contain efferent motor neurons, which control the body’s periphery.

Detailed explanation-3: -Final answer: The part of the nervous system involved in reflex action is the spinal cord.

Detailed explanation-4: -A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain.
