B FIBERS Meaning and
Definition
-
B fibers refer to a specific classification of nerve fibers found in the peripheral nervous system. They are part of the larger A-B-C classification system, which categorizes nerve fibers based on their conduction velocity and diameter. B fibers are typically smaller in diameter and have slower conduction velocities compared to their counterparts, the A fibers.
These B fibers primarily transmit sensory signals from the body's organs and glands to the central nervous system (CNS), and also carry motor signals from the CNS to these target structures. They are responsible for conveying some visceral sensations, such as pain, temperature, and pressure, originating from internal organ systems like the heart, lungs, gastrointestinal tract, and more.
Due to their slower conduction velocities, B fibers are involved in transmitting longer-lasting and chronic pain signals. They play a crucial role in the perception of dull, aching pains that arise from internal organs. While their slower transmission speed may not be ideal for rapid reflex actions or transmitting time-sensitive information, including sharp or acute pain, B fibers provide essential functions related to visceral sensation and motor control of internal organs.
In summary, B fibers are a specific group of nerve fibers that transmit sensory and motor signals pertaining to internal organs. Their slower conduction velocities and smaller diameters distinguish them from other nerve fiber types within the peripheral nervous system.
