MICROANATOMY

Detailed explanation-1: -Afferent nerve fibers are axons (nerve fibers) of sensory neurons that carry sensory information from sensory receptors to the central nervous system. Many afferent projections arrive at a particular brain region. Afferent nerve fibers transmit information from the peripheral to the central nervous system.

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. The ventral horns contain efferent motor neurons, which control the body’s periphery.

Detailed explanation-4: -Each spinal nerve is a mixed nerve that contains afferent and efferent, somatic and autonomic fibers.

Detailed explanation-5: -The Major Afferent Pathway for Mechanosensory Information: The Dorsal Column-Medial Lemniscus System. The action potentials generated by tactile and other mechanosensory stimuli are transmitted to the spinal cord by afferent sensory axons traveling in the peripheral nerves.
