Detailed Solution

Afferent nerve fibers, also known as sensory nerve fibers, are responsible for transmitting sensory information from the peripheral nervous system (like skin, muscles, and organs) towards the central nervous system (brain and spinal cord). These fibers convey signals related to touch, pain, temperature, pressure, and other sensations from the body to the brain, allowing us to perceive and respond to our environment.

Afferent nerve fibers transmit signals towards the central nervous system, unlike efferent fibers that transmit signals away from it.

Voluntary muscle movements are primarily controlled by efferent nerve fibers, not afferent ones responsible for sensory transmission.

Efferent nerve fibers, not afferent ones, conduct signals to effectors like muscles and glands, enabling motor responses.
