At approximately what age does nerve conduction achieve maximum capacity?
a.30
b.5
c.10
d.20

At approximately at the age of 5 nerve conduction achieve maximum capacity.

Explanation:

The maximum nerve conduction values achieve its maximum capacity age 4. When conduction speeds in infants and little children is compared with that of the adults it can be observed that the value of the child when doubled leads to the value of the adults.  

Nerve conduction studies performed on adults, uncovered that age is adversely connected with the tactile abundancy proportions of the Median, Ulnar, and Sural nerves.

the answer would be d : p
