k0ka [10]

Answer:

WATER REABSORPTION IN THE COLLECTING TUBULE OF TE KIDNEY

Explanation:

Antidiuretic hormone synthesized by the neurons in the hypothalamus and the posterior pituitary allows for the reabsorption of water from the collecting ducts of the kidneys back into the circulation.

This therefore reduces the amount of water in the urine causing the formation of concentrated urine and reduced volume of urine.

It causes the increased reabsorption of sodium in the ascending loop of Henle adding to the counter-current mechanism which aids the further reabsorption of water from the distal tubules and collecting ducts.

It also allows the constriction of arteries thereby reducing arterial blood pressure.

What is required for the production of anterior pituitary gland hormones?
Lapatulllka [165]

Answer:

The correct option is c) hormonal stimuli

Explanation:

The pituitary gland, located in the anterior brain, under the hypothalamus, is formed by two lobes of very different origin. The anterior lobe or adenohypophysis, evolves as an evagination in the upper part of the mouth, from which it separates and grows towards the brain; the posterior lobe or neurohypophysis, is formed from the hypothalamus and joins the anterior lobe. The hypothalamus decides that hormones should release the pituitary by sending hormonal (hormonal stimuli) or electrical messages.

The secretion of hormones from the anterior lobe of the pituitary gland is regulated by hypothalamic stimulation factors, transported through a local blood network, the pituitary portal system. In response to hormonal stimuli of the hypothalamus, the anterior pituitary gland secretes growth hormones, the thyroid stimulating hormone (which affect the secretion of hormones from the adrenal cortex and thyroid gland respectively), the corticotropic hormone stimulates the secretion of hormones from the adrenal cortex: cortisol, which influences blood glucose levels, and aldosterone, which increases sodium retention in the kidneys, among others.
