A-Delta Fibers
A-Delta fibers are a type of nerve fiber found in the peripheral nervous system. They are classified as myelinated fibers, which means they have a protective sheath that helps speed up the transmission of electrical signals. A-Delta fibers are primarily responsible for transmitting sharp, acute pain sensations and temperature changes.
These fibers are larger in diameter compared to other nerve fibers, such as C fibers, which transmit dull, chronic pain. A-Delta fibers play a crucial role in the body's ability to respond quickly to harmful stimuli, allowing for immediate reactions to potential injuries or threats.
