Example Question #27 : Gland Physiology
Which of the following is not a tropic hormone?
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?
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?
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?
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 __________.
superficial relief,interstitial fluid
transport media, physical protectors
Exocrine glands are released through ducts and typically release enzymes, while endocrine glands are not released through ducts and produce hormones.
