Question 9

Myelination enhances sensitivity dependent/independent of diameters.

Answer 9

independent of diameter

Question 10

Small/large diameter highly active nerves tend to be more sensitivity.

Answer 10

small diameter nerve = more sensitive

Question 11

Large diameters are less sensitive and thus recover quicker/slower than small.

Answer 11

Quicker = less sensitive
