Axons are classified into three major groups called A, B, and C, based on their ____________ . Group A has a conduction velocity that may be ____________ per second; these fibers have both a ____________ and are ____________ . Group B conducts at approximately ____________ per second. Group C conducts at ____________ per second. Group B and group C fibers generally have a ____________ and are ____________ .

Respuesta :

Answer:

1. Based on their physical features and conduction properties

2. 80m/s to 120m/s

3. Has both sensory fibers and motor fibers

4. Group B conduct at 3m/s to 15m/s

5. Group C conduct at 0.5m/s to 15m/s

6. They generally have low conduction velocity and are polymodal

Explanation:

Axons were know to have different thickness and this differences were thought to relate to the speed at which the action potential could travel. This hypothesis was proved by Erlanger and Gasser.
