The hormone that is primarily involved in the control of bone remodeling is calcitonin.
Ainat [17]

Answer:

The correct answer will be-False

Explanation:

Calcitonin is a hormone produced by the parafollicular cells present in the thyroid gland. The Calcitonin plays an important role in the human body as they reduce the level of phosphate and calcium in the blood.

The calcitonin is produced by the C-cells in response to the amount of the calcium levels in the blood as a high concentration of calcium cause release of calcitonin.

Since the calcitonin is involved in the regulation of calcium of blood and not bones therefore, false is the correct answer.

Estimate how much the brain would swell due to osmosis if the concentration of the cerebrospinal fluid fell to 280mM. In other w
AnnZ [28]

Answer:

The correct answer is 6.67 %.

Explanation:

The average osmotic pressure of the brain is 300 mM

Given the concentration of solution is 280 mM

Difference is 300 - 280 = 20 mM

This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.  

Also, it is known that the volume of brain is about 1200 ml on an average,  

Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml

Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
