The Endocrine System
The quizlet for the endocrine system. This test is gonna be impossible.
Glandular secretory cells that release their secretions into the extracellular fluid
Chemical messengers that are released in one tissue and transported by the bloodstream to reach target cells
Hormones consisting of chains of amino acids
Lipid hormones that are derived from cholesterol
Hormones that coordinate local cellular activities.
The cell that is the destination of a released hormones
A sensor in the cell membrane, or in the cytoplasm that allows the cell to respond to the presence of a hormone
The hormone that binds to the receptor in the cell membrane
The substance in the cytoplasm that responds to the activation of a receptor in the membrane
An enzyme that is coupled to a membrane receptor
One of the most important second messengers. Its appearance depends on the presence of Adenylate Cyclase.
Converts ATP into a ring shaped molecule of cAMP
Special hormones that control the activity of endocrine cells in the anterior pituitary.
Stimulate the production of one or more hormones in the anterior pituitary.
Inhibit the production of one or more hormones in the anterior pituitary.
The entire system of portal veins
Hypophyseal Portal System
The Portal system in the hypothalamus
Thyroid Stimulating Hormone
Targets the thyroid gland and triggers the release of thyroid hormones
Stimulates the release of several hormones by the adrenal cortex.
This gland secretes nine different hormones, all hormones use cAMP as a second messenger.
Slender stalk connecting the hypothalamus to the pituitary gland.
Anterior Pituitary Gland
This gland contains endocrine cells surrounded by an extensive capillary network called the hypophyseal portal system.
Hormones that regulate the activities of the male and female sex organs
Follicle Stimulating Hormone
Promotes follicle and ova development in females and stimulates secretion of estrogens.
Induces ovulation and promotes secretion of estrogens and progestins.
Hormones that prepare the body for pregnancy.
Male sex hormones produced by the testes
Works with other hormones to produce breast milk by the mammary glands
Stimulates cell growth and replication by accelerating the rate of protein synthesis.
Hormones produced by liver cells in response to the presence of growth hormone
Melanocyte Stimulating Hormone
Stimulates the pigment cells in the skin increasing the amount of pigment produced.
Posterior Pituitary Gland
This gland contains axons from two different groups of neurons located within the hypothalamus.
Hormone released in response to such stimuli as a rise in the concentration of electrolytes in the blood. Reduces the amount of water lost in the urine.
Hormone that stimulates smooth muscle contractions in the uterus, and pushes milk out of the mammary glands.
Gland that lies anterior to the trachea, and just inferior to the thyroid cartilage.
Forms most of the anterior surface of the larynx covers the thyroid.
Spheres lined by a simple cuboidal epithelium in the thyroid gland
Hormone secreted by the thyroid contains four iodine atoms, makes up 90% of thyroid secretions.
Related more potent molecule than thyroxine containing three iodine atoms
When the metabolic rate raises, and more heat is produced.
Endocrine cells sandwiched between the follicle cells and their basement membrane. Produce calcitonin.
Hormone that helps regulate calcium ion concentrations in body fluids.
Glands embedded in the posterior surfaces of the thyroid gland.
Cells that produce parathyroid Hormone
Hormone that stimulates osteoclasts, inhibits the bone building functions of osteoblasts.
Glands that sit on the top of the kidneys, has two sections
Yellowish in color due to presence of lipids, part of the adrenal gland
Steroid hormones produced by the adrenal cortex.
Hormones that affect the electrolyte composition of body fluids.
Stimulates the conservation of sodium ions by targeting cells that regulate the ionic composition of excreted fluids.
Hormones that affect glucose metabolism
Cortisol, Corticosterone, Cortisone
The three glucocorticoids in "ex, ex, ex" fashion
Sex hormones produced in both sexes by the adrenal cortex
Reddish brown part of the adrenal glands
Hormone responsible for the fight or flight response
Hormone responsible for the Anti-fight or flight response
Gland lying in the posterior portion of the roof of the third ventricle.
Hormone that inhibits reproductive function, antioxidant activity, and day/night cycles.
Organ that lies in the j-shaped loop between the stomach and the proximal portion of the small intestine.
Clusters of the endocrine pancreas
Cells in the pancreas that produce glucagon
Cells in the pancreas that produce insulin
Secreted when blood glucose levels go above normal
Secreted when blood glucose levels go below normal
Hormone secreted by the kidneys in response to PTH.
Hormone secreted by the kidneys in response to low oxygen levels in kidney tissues.
Hormone secreted by the kidneys in response to a decrease in blood volume, pressure, or both.
Hormone released by the kidneys, stimulates production of aldosterone.
Organ located in the mediastinum, posterior to the sternum, releases thymosins
Hormones released by the thymus, aid in lymphatic and immune defenses.
Cells in the testes that produces androgens
Hormone produced by the testes, most important androgen
Hormone secreted by the testes, inhibits secretion of FSH
Structures in the ovaries in which ova develop under stimulation by FSH.
Hormones produced by the cells surrounding the ova that support the maturation of the ova and the growth of the uterine wall.
The follicular cells reorganize into a ______ after ovulation
Hormone that accelerates the movement of fertilized eggs along the uterine tubes.
Hormone secreted by the adipose tissue, regulates appetite.
Hormone secreted by adipose tissue, reduces insulin sensitivity
When two hormones have opposite effects
When two hormone have the same effect and add to a greater effect
When two hormones have a greater effect than their sum
When two hormones have complementary effects
