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.
