Question 15

Which equation would you use to calculate the threshold for tactile sensation?

Accepted Answer

$Threshold = \frac{Stimulus_{min}}{Receptor_{sensitivity}}$

Question 16

Which of the following is the correct formula for calculating the number of taste buds on circumvallate papillae if there are $n$ papillae and each contains about 100 taste buds?

Accepted Answer

$Taste\ Buds = n 	imes 100$
