What are the names of various types nerves as per classification in term their speed conduction?

Nerve fibers are classified into three types based on their speed of conduction: A fibers, B fibers, and C fibers.

A fibers are the largest and fastest-conducting nerve fibers. They are myelinated, which means that they are covered in a fatty substance called myelin. Myelin acts as an insulator, preventing the electrical signals from leaking out of the nerve fiber. This allows A fibers to conduct signals at speeds of up to 120 meters per second.

B fibers are smaller than A fibers and are also myelinated. However, they conduct signals at a slower speed, up to 15 meters per second. B fibers are responsible for conducting signals from the skin to the brain, allowing us to feel sensations such as touch, pain, and temperature.

C fibers are the smallest and slowest-conducting nerve fibers. They are unmyelinated, which means that they do not have a myelin sheath. This causes C fibers to conduct signals at speeds of only 1 to 2 meters per second. C fibers are responsible for conducting signals from the internal organs to the brain, allowing us to feel sensations such as hunger, thirst, and pain.

Here is a table summarizing the different types of nerve fibers:

| Fiber Type | Size | Myelination | Speed of Conduction | Function |

|---|---|---|---|---|

| A fibers | Largest | Myelinated | Up to 120 meters per second | Conducting signals from the brain to the muscles and sensory organs |

| B fibers | Smaller than A fibers | Myelinated | Up to 15 meters per second | Conducting signals from the skin to the brain |

| C fibers | Smallest | Unmyelinated | Only 1 to 2 meters per second | Conducting signals from the internal organs to the brain |
