The glucose used by the neurons for ATP production comes fro

The glucose used by the neurons for ATP production comes from:

a) Nutrients absorbed from digestion and glucose produced by the liver.

b)The breakdown of fat in adipose tissue and glycogen in muscle tissue.

c)Only Nutrients absorbed from digestion.

d)Only gluconeogenesis in the liver.

What can receptors detect?

a)Loss of homeostasis

b)Loss of homeostasis and a return to homeostasis.

c) A return to homeostasis.

d)Need for medical attention.

Which of the following is not a role of the skeletal system in maintenance of homeostasis?

a) Calcium Storage

b) Protection

c) Support

d) Phosphorous storage

What controls blood pressure in your body?

a) The hypothalamus

b) pituitary gland.

c) medulla oblongata

d) all of the above

What increases blood pressure?

a) Decreased heart rate.

b) Decreased blood vessel resistance

c) Increased blood volume

d) all of the above

What ends a hormonal response to increase blood pressure?

a) Low blood pressure

b) High blood pressure

c) A return to homeostasis.

d) Low blood pressure and a return to homeostasis.

Solution

1) The glucose used by the neurons for ATP production comes from:

a) Nutrients absorbed from digestion and glucose produced by the liver.

Both are the direct and indirect sources of glucose, prior one on regular basis while later one is during starvation conditions.

2) What can receptors detect?

b )Loss of homeostasis and a return to homeostasis.

Receptors detect both the conditions as brain has to maintain equilibrium over all parameters like temp., blood pressure.

3) Which of the following is not a role of the skeletal system in maintenance of homeostasis?

d) Phosphorous storage

Phosphorus is not directly involved in process of homeostasis.

4) What controls blood pressure in your body?

a) The hypothalamus

b) pituitary gland.

c) medulla oblongata

d) all of the above

· The main function of the hypothalamus is homeostasis

· Pituitary gland secrets ant diuretic hormone (ADH) into the bloodstream upon signaling by hypothalamus

· baroreceptors sends messages to the cardio regulatory center of medulla oblongata to regulate blood pressure

· So all the above mentioned organs are involved in Blood pressure regulation directly or indirectly

5) What increases blood pressure?

c) Increased blood volume

due to Increase in blood volume heart needs to pump more blood which increases Blood Pressure

Decreased heart rate and Decreased blood vessel resistance will decrease blood pressure

5) What ends a hormonal response to increase blood pressure?

d) Low blood pressure and a return to homeostasis.

Hormonal response ends when blood pressure comes to normal and at equilibrium or homeostatic condition
