B FIBER Meaning and
Definition
-
B fiber refers to a type of nerve fiber, specifically classified as Type II, that is involved in the transmission of sensory information from various organs and tissues back to the central nervous system. These fibers are part of the larger network of nerve fibers known as the peripheral nervous system.
B fibers are characterized by their relatively small diameter and moderate conduction velocity compared to other types of nerve fibers. They are responsible for transmitting information related to touch, pressure, and vibration, as well as proprioception, which is the sense of position and movement of the body. B fibers are also involved in the autonomic nervous system, which controls involuntary bodily functions such as heart rate and digestion.
The transmission of signals along B fibers is facilitated by a protective sheath called myelin, which wraps around the fiber and helps increase the speed and efficiency of nerve impulses. The myelin sheath is produced by specialized cells known as Schwann cells. The presence of myelin distinguishes B fibers from non-myelinated C fibers, which transmit pain and temperature sensations.
Overall, B fibers play a crucial role in relaying sensory information to the central nervous system, allowing for the perception and interpretation of various stimuli. Understanding the function and characteristics of B fibers is essential in the study of neurophysiology and the diagnosis and treatment of sensory-related disorders.
