Answer 1

Type A nerve fibers are further subdivided into four groups based on size and conduction velocity. These groups are Type A alpha fibers, Type A beta fibers, Type A gamma fibers, and Type A delta fibers.

Step-by-step explanation:

Type A nerve fibers are further subdivided into four groups based on size and CV. The four subgroups are:

1. Type A alpha fibers - large diameter, high conduction velocity
2. Type A beta fibers - medium diameter, medium conduction velocity
3. Type A gamma fibers - small diameter, low conduction velocity
4. Type A delta fibers - small diameter, medium conduction velocity

The classification of nerve fibers into these groups is based on their size and the velocity at which they conduct nerve impulses. Each group has different properties and functions in the transmission of sensory and motor information in the peripheral nervous system.
