How does the hypothalamus regulate the release of hormones from the anterior pituitary gland ? A.) It releases Na+ to trigger hormone release by the anterior pituitary cells. B.) It sends nerve impulses to the glandular cells of the anterior pituitary. C.) It secretes releasing and inhibiting hormone that travel through the blood to the anterior pituitary gland. D.) It sends nerve impulses along axons that release hormones within the anterior pituitary gland.

It secretes releasing and inhibiting hormone that travel through the blood to the anterior pituitary gland.

Justin has discovered he is sterile. Hyposecretion of which of the following hormones might be causing Justin's sterility ? A.) Oxytocin B.) Luteinizing hormone C.) Prolactin D.) Thyrotropic hormone

Luteinizing hormone

What is the primary effect of prolactin ? A.) Trigger ovulation of an egg from the ovary B.) Stimulate follicle development in the ovaries C.) Promote milk ejection in a woman nursing her infant D.) Stimulate and maintain milk production after childbirth E.) Stimulate4 contractions of the uterus during breastfeeding

Stimulate and maintain milk production after childbirth

What role does insulin play in maintaining homeostasis ? A.) Insulin raises blood pressure after a meal to promote digestion and absorption. B.) When blood glucose levels are elevated after a meal, insulin stimulates glucose uptake by cells to bring glucose levels back to normal. C.) Insulin causes glucose to spill into the urine when blood glucose levels are too high. D.) Between meals, blood glucose levels decrease. Insulin stimulates the liver to release glucose into the blood and bring glucose levels into normal range.

When blood glucose levels are elevated after a meal, insulin stimulates glucose uptake by cells to bring glucose levels back to normal.
