GROSS ANATOMY

Detailed explanation-1: -Type A fibers are the afferent fibers of nociceptors. A fibers carry information from peripheral mechanoreceptors and thermoreceptors to the dorsal horn of the spinal cord.

Detailed explanation-2: -Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain. Sensory information may involve special senses, such as vision, hearing, smell, or taste, as well as the sense of touch, pain, and temperature.

Detailed explanation-3: -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-4: -The sensory (afferent) division carries sensory signals by way of afferent nerve fibers from receptors in the central nervous system (CNS).

Detailed explanation-5: -Afferent nerve fibers are the axons (nerve fibers) carried by a sensory nerve that relay sensory information from sensory receptors to regions of the brain. Afferent projections arrive at a particular brain region. Efferent nerve fibers are carried by efferent nerves and exit a region to act on muscles and glands.
