3. The response to an increase in the level of antidiuretic healthy human being would include J Increased urine output K Decreased production of insulin L Decreased blood pressure M Increased water reabsorption 4. Which one of the following nerve pathways represents the reflex response to the stimulus of stepping on a sharp object? J Receptor → motor nerve → spinal cord → sensory nerve → muscle in foot K Receptor → motor nerve →brain → sensory nerve → muscle in leg L Receptor → sensory nerve → brain → motor nerve → muscle in foot • M Receptor → sensory nerve → spinal cord → motor nerve → muscle in leg 5. Which one of the following responses is most likely to occur when the body temperature of a healthy human becomes too low? J An increase in the production of the hormone thyroxine, causing a decrease in the metabolic rate K A decrease in the production of the hormone thyroxine, causing a decrease in the metabolic rate L An increase in the blood flow to the skin surface, causing a decrease in the amount of heat loss. • M A decrease in the blood flow to the skin surface, causing a decrease in the amount of heat loss.
