Example Questions

Example Question #27 : Gland Physiology

Which of the following is not a tropic hormone?

Possible Answers:

Glucagon

Thyroid-stimulating hormone

Gonadotropin-releasing hormone

Luteinizing hormone

Adrenocorticotropic hormone

Correct answer:

Glucagon

Explanation:

Tropic hormones stimulate the release of other hormones from other glands.

Adrenocorticotropic hormone (ACTH) stimulates the release of glucocorticoids (namely cortisol) from the adrenal cortex. Thyroid-stimulating hormone (TSH) stimulates the release of thyroid hormones (T3 and T4) from the thyroid gland. Gonadotropin-releasing hormone (GnRH) stimulates the release of luteinizing hormone (LH) and follicle-simulating hormone (FSH) from the anterior pituitary. LH stimulates the release of testosterone (and other sex hormones) from the testes in men, and the release of estrogen and progesterone (and testosterone) from the ovaries in women.

Glucagon is released from the pancreas, and acts directly on cells in the liver and skeletal muscle to stimulate the breakdown of glycogen to increase blood sugar while fasting.

Example Question #28 : Gland Physiology

How are steroid hormones released from the secretory cell?

Possible Answers:

Facilitated diffusion

Apoptosis

Simple diffusion

Exocytosis

Correct answer:

Simple diffusion

Explanation:

Steroid hormones are released from the parent cell by simple diffusion. Thyroid hormones are also released via simple diffusion. Peptide and catecholamines are the hormones released by exocytosis. No hormones are released via apoptosis, which is a controlled, deliberate form of cell death. 

Example Question #29 : Gland Physiology

There are a few tissues which are primarily endocrine in function, where other tissues serve other purposes besides endocrine function, but do contain endocrine functions too.

Which of the following tissues is not primarily endocrine in function? 

Possible Answers:

Adrenal glands

Parathyroid glands

Kidneys 

Pituitary gland

Pineal gland

Correct answer:

Kidneys 

Explanation:

The kidneys contain many other functions in the body other than endocrine function. One of the primary functions of the kidneys is urine production. The kidney's endocrine function is the synthesis and secretion of erythropoietin and renin. The pineal, parathyroid, adrenals, pituitary, and thyroid tissues are the tissues that are primarily endocrine in function. 

Example Question #1 : Help With Other Endocrine Physiology

What do the lacrimal glands produce?

Possible Answers:

Milk

Saliva

Tears

Sweat

Correct answer:

Tears

Explanation:

The lacrimal glands are responsible for producing tears. The eccrine glands produce sweat. The mammary glands produce milk. The salivary glands produce saliva. 

Example Question #2 : Help With Other Endocrine Physiology

Secretions through a duct might provide __________, whereas ductluss secretions act as __________.

Possible Answers:

superficial relief,interstitial fluid

transport media, physical protectors

 

lubrications, lubricators

enzymes, hormones

Correct answer:

enzymes, hormones

Explanation:

Exocrine glands are released through ducts and typically release enzymes, while endocrine glands are not released through ducts and produce hormones.
