Flashcards in CH 12 Endocrine System Deck (32):
1

A hormone produced by the adrenal cortex that is important in the regulation of water and salt balance in the body

aldosterone

2

cells located in the islet of langerhans that secrete glucagon

alpha cells

3

male sex hormones

androgens

4

one of the two portions of the pituitary gland; it produces hormones that are not neurohormones; also called the andeohypophysis

anterior pituitary lobe

5

a hormone secreted by the posterior pituitary lobe of the pituitary gland, it constricts blood vessels and raises the blood pressure, also called vasopressin

antiduiretic hormone (ADH)

6

cells located in the islets of langerhans that secrete insulin

beta cells

7

a hormone produced by the parafollicular cells of the thyroid gland that is important in the regulation of calcium levels in the body

calcitonin

8

any of several steroids secreted by the adrenal gland

corticosteroids

9

a disorder of the pituitary gland that results in large volumes of dilute urine

diabetes insipidus

10

a condition that results from impaired production of insulin by the pancreas

diabetes mellitus

11

glands that empty secretions (hormones) directly into the blood

endocrine glands

12

a system of glands located throughout the body that secrete hormone that regulate many body functions, including growth, reproduction, temperature, metabolism, and blood pressure

endocrine system

13

glands that empty their products through ducts, usually onto epitherlial surfaces

exocrine glands

14

a process that stimulates both the liver and the kidneys to produce glucose from noncarbohydrate molecules

gluconeogenesis

15

a long polymer from which glucose is converted in the liver (animal starch)

glycogen

16

proteins secreted by glands to regulate body functions

hormones

17

the gland that secretes hormones that regulate the function of many other glands in the body; also called the pituitary gland

hypophysis

18

basal part of the diencephalon, it regulates the function of the pituitary gland

hypothalamus

19

compounds that travel from the hypothalamus to the pituitary gland in specialized set of blood vessels; also called releasing factors

inhibiting factors

20

a specialized group of cells in the pancreas where insulin and glucagon are produces

islets of langerhans

21

the concept that once the desired effect of a hormone has been achieved, further production of the hormone is inhibited until it is needed again; also called feedback inhibition

negative feedback

22

hormones that are secreted by the posterior pituitary lobe

neurohormones

23

a hormone that causes the smooth muscles of the pregnant uterus to contract and milk to be released from the breasts of lactating women

oxytocin

24

an organ of both the endocrine and digestive systems, it produces the hormones insulin and glucagon

pancreas

25

four glands that are embedded in the posterior portion of each lobe of the thyroid, they produce and secrete parathyroid hormone

parathyroid glands

26

the gland that secretes hormones that regulates the function of many other glands in the body; also called the hypophysis

pituitary gland

27

the concept that once the desired effect of a hormone has been achieves, production of the hormone is continued

positive feedback

28

hormone that plays an important role in milk production in women

prolactin

29

a group of hormone-like fatty acids that are produced in many body tissues, including the uterus, brain and kidneys

prostaglandins

30

compounds that travel from the hypothalmus to the pituitary gland in a specialized set of blood vessels; also called inhibiting factors

releasing factors

31

a large endocrine gland that is located at the base of the neck and produces and excretes hormones that influence growth, development and metabolism

thyroid gland

32

a hormone that controls the release of thyroid hormone from the thyroid gland; also called thyrotropin

thyroid-stimulating hormone (TSH)
