Explanation / Answer

Ans 36) e) All of the above

The human growth hormones are present in all the human cells and helps in promoting the growth of the cells. It helps in stimulating the division and proliferation of the chondrocytes. It increase lipolysis and it is long known as lipolytic hormone. It helps in the growth and division of the skeletal muscle cells and enhances the level of glucose in blood.

Ans 37) e) All are action of PTH

The parathyroid hormone helps in regulating the levels of calcium in our body. When the calcium reduces in the blood, the hormones triggers release of the calcium to normal and after it becomes normal or too high, it stops release of the hormones. It helps in balancing the concentration of calcium in the body.

Ans 38) e) All of the above

In all of the above conditions the aldosterone is released where due to decrease in the blood pressure or volume, the adrenal gland is stimulated and it tends to release the hormone in presence of the angiontensin II

Ans 39) e) All of the above

The cortisol hormone promote the gluconeogenesis in liver and has anti-inflammatory function which helps in stimulating the leukocyte production by stimulating the immune system

Ans 40) a) entering the nucleus of a cell and initiating gene activation

The hormones help in activating or initiating the gene activation by entering through the nucleus of the cell.

Ans 41) b) Islets

The endocrine part of the pancreas consists of small cells which help in synthesizing and secreting the hormones. They have small cluster of cells which are known as Islets of Langerhans or simply they are known as the Islets

Ans 42) e) All of the above

The insulin is a hormones which helps in maintaining the sugar level in the blood. It helps in storing of the glucose in liver in form of glycogen. It indirectly also helps in formation of the triglyceride in the adipose tissues. It also helps the cells to uptake the glucos
