ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.

Detailed explanation-3: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.

Detailed explanation-4: -The Spinal Cord Transmits Signals to and from the Brain and Commands Reflexes. The spinal cord is an elongated cylinder of neuron cell bodies, bundles of axons and other cells, protected by connective tissue and bone.
