The hypothalamus and core thermoreceptors notice if body temp too low. The hypothalamus signals smooth muscle in blood vessels to vasoconstrict and skeletal muscle to shiver. This activity causes body temp to rise, which is again noticed by hypothalamus & core thermoreceptors, so the hypothalamus turns off these heat gain mechanisms. In this scenario, which of the following state-ments is correct?
A. The scenario describes positive feedback in action.
B. The core thermoreceptors are the effector organs.
C. The hypothalamus is the control centre.
D. Skeletal muscle is the efferent pathway to the effector organ.
Answer is C: The hypothalamus interprets the sensory input and determines the response. Choice A is wrong as this is negative feedback. The effector organs are the skeletal muscles (which are not a "pathway").

Sagot :

The control center is the hypothalamus. When body temperature is too low, the hypothalamus and core thermoreceptors detect it.

Which of the following describes a body's negative feedback reaction to hyperthermia?

The body has a negative feedback system that regulates body temperature. Shivering or sweating in reaction to an increase or decrease in body temperature will undo the effect of the change.

How does feedback fit into thermoregulation?

A prime example of negative feedback is thermoregulation. The thermostatic master switch that controls the body's core temperature is located in the brain's hypothalamus. The hypothalamus can start a number of actions to reduce the temperature if it is too high.
