Question 1

You are "shadowing" an endocrinologist who is examining a patient complaining of weakness,weight loss,and heat intolerance.The doctor points out the patient's obvious exophthalmos and asks for your diagnosis.What would you speculate is the patient's problem

Accepted Answer

The patient's symptoms of weakness, weight loss, and heat intolerance along with the presence of exophthalmos are classic signs of hyperthyroidism, which is caused by an overproduction of thyroid hormone.

Question 2

The release of hormones from the adrenal cortex is stimulated by

Accepted Answer

The release of hormones from the adrenal cortex is stimulated by adrenocorticotropic hormone (ACTH), which is produced by the anterior pituitary gland. ACTH stimulates the production and release of cortical hormones, such as cortisol and aldosterone, from the adrenal cortex.

Question 3

The primary function of adrenocorticotropic hormone (ACTH)is to

Accepted Answer

The primary function of adrenocorticotropic hormone (ACTH) is to stimulate glucocorticoid release from the adrenal glands. ACTH is produced and secreted by the anterior pituitary gland in response to corticotropin-releasing hormone (CRH) from the hypothalamus. Once released, ACTH stimulates the adrenal cortex to produce and release glucocorticoids, such as cortisol, which play a role in regulating metabolism, immune function, and response to stress.

Question 4

Until thyroid hormone needs to be secreted,precursors to it are stored in a viscous,protein-rich fluid within the center of thyroid follicles.This viscous fluid is known as _________.

Accepted Answer

The answer of Until thyroid hormone needs to be secreted,precursors...

Question 5

Where are the target cells for follicle-stimulating hormone

Accepted Answer

Follicle-stimulating hormone (FSH) targets the gonads, specifically the ovaries in females and the testes in males, where it stimulates the growth and development of follicles in the ovary and the production of sperm in the testes.

Question 6

Thyroid-stimulating hormone (TSH)is secreted by the

...

Question 7

Which is not a tropic hormone

Accepted Answer

Prolactin is not a tropic hormone. Tropic hormones are hormones that regulate the secretion of other hormones from specific glands. Thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), and follicle-stimulating hormone (FSH) are all examples of tropic hormones. Prolactin, on the other hand, stimulates milk production in the mammary glands and does not regulate the secretion of other hormones.

Question 8

Which is not correct regarding growth hormone (GH)

Accepted Answer

GH stimulates the liver to secrete somatomedin, not the kidney.

Question 9

Which is not true about the thyroid gland

Accepted Answer

The thyroid gland has two lobes connected by a central portion called the isthmus, not the commissure.

Question 10

The hypothalamic hormone that triggers the release of adrenocorticotropic hormone (ACTH)is

Accepted Answer

The hypothalamic hormone that triggers the release of adrenocorticotropic hormone (ACTH) is corticotropin-releasing hormone (CRH).

Question 11

The thyroid gland is located

Accepted Answer

The thyroid gland is located immediately anterior to the trachea, in the neck.

Question 12

Exercise causes a(n)_______ in growth hormone (GH)levels;a rise in amino acid levels or decrease in glucose levels causes a(n)________ in GH levels.

Accepted Answer

The answer of Exercise causes a(n)_______ in growth hormone (GH)levels;a...

Question 13

Which hormone group is not secreted by the adrenal cortex

Accepted Answer

All hormone groups (corticosteroids, glucocorticoids, mineralocorticoids, and gonadocorticoids) are secreted by the adrenal cortex.

Question 14

When follicular cells of the thyroid are stimulated to secrete thyroid hormone (TH),they take up TH precursors from the inside of the follicle,transport and enzymatically modify them within a lysosome,and release TH to the blood.

Accepted Answer

This statement is true. Follicular cells of the thyroid take up TH precursors from the inside of the follicle, transport and enzymatically modify them within a lysosome, and release TH to the blood when stimulated to secrete thyroid hormone.

Question 15

Thyroid hormone synthesis involves secretion of a glycoprotein called ___________ by the follicular cells.

Accepted Answer

Thyroid hormone synthesis involves secretion of thyroglobulin by the follicular cells. This glycoprotein is then metabolized and processed to form the active thyroid hormones T3 and T4.

Question 16

Which hormones are collectively called the gonadotropins

Accepted Answer

The hormones that are collectively called the gonadotropins are follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones target the gonads (ovaries or testes) to stimulate the production of gametes (eggs or sperm) and the release of sex hormones (estrogen, progesterone, and testosterone). Prolactin and oxytocin are involved in milk production and release, while antidiuretic hormone regulates water balance in the body. Follicle-stimulating hormone is not associated with growth hormone, thyroid-stimulating hormone, or adrenocorticotropic hormone.

Question 17

Thyroid hormone's effects are to

Accepted Answer

The answer of Thyroid hormone's effects are to
...

Question 18

Growth hormone is secreted by __________ cells in the anterior pituitary.

Accepted Answer

Growth hormone is secreted by somatotropic cells in the anterior pituitary.

Question 19

Growth hormone releasing hormone (GHRH)is one of the regulatory hormones released by the hypothalamus that acts on the pituitary.

Accepted Answer

This statement is true. GHRH is a regulatory hormone released by the hypothalamus that stimulates the release of growth hormone from the pituitary gland.

Question 20

Excessive secretion of growth hormone in adults can cause

Accepted Answer

Excessive secretion of growth hormone in adults can lead to acromegaly, which causes various physical changes such as enlarged hands, feet, and facial bones as well as increased risk of cardiovascular disease, diabetes, and certain types of cancer. A, C, D, and E are not caused by excessive secretion of growth hormone in adults.
