Question 1

How are called the sensory receptors for temperature ?

Answer 1

Thermoreceptors, the ones located in the skin are called peripheral thermoreceptors, the ones sensitive to cold temperature are more numerous. The ones located in the core are called central thermoreceptors.

Question 2

From the thermoreceptors, neurons are carrying sensory input into the brain, what is the region of the brain controlling temperature ?

Answer 2

Hypothalamus : in the preoptic nucleus

Question 3

The motors effect differ if they have to increase or decrease temperature of the body, true or false?

Answer 3

True

Question 4

What is the hypothalamic set-point ?

The temperature that the hypothalamus considers as “normal”

Question 5

What is the first thing to happen in the body with a cold environment?

Blood vessels constrict in the skin, resulting in slowing down blood flow in the shell and keeping more blood flow in the core

Question 6

What is shivering?

Answer 6

Rapid fluctuation in contraction state in your muscles in order to produce ATP and to promote extra heat production

Question 7

When environmental temperature increases above a level, the blood vessels will dilate to loose extra heat from the body, how do you call this phenomenon ?

Answer 7

Radiation, and if the air is moving ( wind or fan) convection will occure
