5. Which of the following is a reflex action?A Torch light on the eye ----- iris constrictedB Put food in the mouth ----- chew the foodC Book too near to the eye ---- move book furtherD Put cream on the hair ---- comb the hair

6. Which of the following pairs of glands and functions is correct? Glands FunctionA Adrenal To regulate blood mineralsB Pancreas To regulate metabolic rateC Testis To regulate blood sugarD Thyroid To control sexual characteristics

7. The function of the sensory neurone is to carry impulse fromA effector to central nervous systemB receptor to central nervous system C central nervous system to spinal cordD central nervous system to effector organ

Stimulus Eyes Brain Move hand to pick up a book
