Endocrine Lab

Potential crap on the endocrine lab test

TermDefinition
Endocrine organ (gland) Any of several diverse ductless glands that play a major role in maintaining the body’s homeostasis through the secretion of hormones into the bloodstream
Hormone Chemical messengers secreted into the bloodstream by endocrine glands that initiate a change in a target cell
Target tissue Tissue that contains the cells with receptors for a particular hormone
Negative feedback A mechanism in which a deviation in a physiological variable triggers a response that restores the variable to its set point; when the set point is restored, the response decreases
Hypothalamus The inferior portion of the diencephalon; releases hormones that stimulate or inhibit the anterior pituitary and two hormones (ADH and oxytocin) stored in the posterior pituitary
Anterior pituitary Anterior portion of the pituitary gland; secretes hormones that largely affect other glands
Posterior pituitary Posterior portion of the pituitary gland; stores ADH and oxytocin produced by the hypothalamus
Thyroid gland Gland located in the anteroinferior neck; composed of thyroid follicles that produce thyroid hormone and calcitonin
Parathyroid glands Three to five small glands located on the posterior thyroid gland; secrete parathyroid hormones that maintain calcium ion homeostasis
Pineal gland Small gland located in the posterior/superior diencephalon; secretes melatonin in response to decreased light levels
Thymus gland Gland located in the superior mediastinum; largest and most active during infancy and childhood when it is actively secreting thymosin and thymopoietin
Pancreas Endocrine and exocrine gland that secretes insulin and glucagon from pancreatic islets
Adrenal cortex Superficial region of the adrenal gland; consists of glandular tissue that secretes steroid hormones
Adrenal medulla The deep region of the adrenal gland that consists of modified sympathetic neurons that secrete epinephrine and norepinephrine in response to sympathetic stimulation
Ovaries Female reproductive organs that produce estrogens and progesterone
Testes Male reproductive organs that produce testosterone
Antidiuretic hormone: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Posterior pituitary (made by the hypothalamus); Collecting and papillary ducts of the kidneys; Increased water reabsorption
Oxytocin: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Posterior pituitary (made by the hypothalamus); Milk ducts and uterus; Milk ejection, uterine contraction
Thyroid-stimulating hormone: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Anterior pituitary; Thyroid gland; Production and secretion of thyroid hormone, growth of thyroid gland
Adrenocorticotropic hormone: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Anterior pituitary; Adrenal cortex; Stimulates secretion of cortisol (and somewhat aldosterone)
Growth hormone: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Anterior pituitary; Nearly all body cells; Stimulates protein synthesis and cell division; increases blood glucose (short-term effect only,decreases blood glucose in the long-term), stimulates lipolysis (short-term effect only)
Prolactin: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Anterior pituitary; Mammary gland; Stimulates milk production
Melatonin: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Pineal gland; Reticular formation in the brainstem; Regulates sleep-wake cycle
Triiodothyonine&Thyroxine (T3&T4): Organ That Secretes the Hormone,Target Tissue(s),Main Effects Thyroid gland; Most body cells; Increases metabolic rate and heat production, promotes growth and development
Calcitonin: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Thyroid gland; Bone; Decreases concentration of calcium ions in the blood by stimulating osteoblasts
Thymosin and thymopoietin: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Thymus;T lymphocytes in the thymus; Stimulates maturation of T lymphocytes
Parathyroid hormone: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Parathyroid glands; Bone, kidneys, small intestine; Increases concentration of calcium ions in the blood by stimulating: osteoclasts, increased absorption of calcium ions from the intestines, and reabsorption of calcium ions from the kidneys
Cortisol: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Adrenal cortex; Most body cells, particularly cells of the liver,adipocytes, and muscle cells; Helps the body adapt to a stressor by triggering gluconeogenesis, lipolysis, release of amino acids into the blood, decreasing inflammation
Aldosterone: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Adrenal cortex; Cells of the distal tubules of the kidneys; Increases reabsorption of sodium (Na+) ions (and water, indirectly) and secretion of potassium (K+) and hydrogen (H+) ions from the kidneys
Epinephrine and Norepinephrine: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Adrenal medulla; Most body cells; Causes the same effects as the sympathetic nervous system
Insulin: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Pancreas; Liver, adipocytes, muscle; Causes glucose uptake into cells to decrease blood glucose
Glucagon: Organ That Secretes the Hormone,Target Tissue(s),Main Effects Pancreas; Liver, adipocytes, muscle; Increases blood glucose through glycogenotysis, gluconeogenesis, stimulates lipolysis
The hypothalamus communicates with the ______ via the hypothalamic-hypophyseal portal system. anterior pituitary gland
T/F? Insulin triggers actions that raise the concentration of glucose in the blood. False: It lowers the concentration
T/F? Interstitial cells within the testes produce testosterone. True
T/F? Aldosterone is the adrenal hormone responsible for the stress response. False: Cortisol is the hormone
T/F? Parathyroid hormone triggers actions that lower the concentration of calcium ions in the blood. False: Parathyroid raises the concentration
T/F? The posterior pituitary produces no hormones of its own. True
Pineal gland hormone(s) Melatonin
Thyroid gland hormone(s) Thyroxine, triiodothyronine, and calcitonin
Pancreas hormone(s) Insulin and glucagon
Thymus hormone(s) Thymosin and thymopoietin
Hypothalamus hormone(s) Antidiuretic hormone and oxytocin
Adrenal cortex hormone(s) Aldosterone and cortisol
Anterior pituitary hormone(s) Follicle stimulating hormone, luteinizing hormone, adrenocorticotrophic hormone, thyroid stimulating hormone, melanocyte stimulating hormone, prolactin, human growth hormone
Adrenal Medulla hormone(s) Epinephrine and norepinephrine

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
