Chapter 18 - Endocrine System

Front 1

both the endocrine an nervous system assume a role in maintaing ______

Back 1

homeostasis

Front 2

nervous and endocrine systems act as a coordinated interlocking super system

Back 2

neuroendocrine system

Front 3

2 kinds of gland in the body

Back 3

endocrine and exocrine

Front 4

secrete their products into ducts and the ducts carry their secretion to the target site

Back 4

exocrine gland

Front 5

secrete their products (hormones) into the interstitial fluid surrounding the secretory cells from which they diffuse into capillaries to be carried away by drugs

Back 5

endocrine glands

Front 6

constitute the endocrine system and include the pituitary, thyroid, parathyroid, adrenal, and pineal glands

Back 6

endocrine glands

Front 7

secretions of endocrine glands

Back 7

hormones

Front 8

1) help regulate the internal environment
2) respond to stress
3) integrate growth and development (biological clock)
4) contribute to reproductive processes
5) regulate organic metabolism and energy balance

Back 8

actions of hormones

Front 9

hormones that travel in blood and act on a distant target cells

Back 9

circulating hormones (endocrines)

Front 10

hormones that act locally w/o first entering the blood stream

Back 10

local hormones

Front 11

local hormones that act on neighboring cells

Back 11

paracrines

Front 12

local hormones that act on the same cells that secrete them

Back 12

autocrine

Front 13

hormone where recpetor port is on the inside, it's derived from cholesterol, hydrophobic and are always bound to carriers, includes steroids, thyroid hormones, and nitric oxide

Back 13

lipid soluble hormone

Front 14

hormones, can be stored, including amines, peptides, proteins, and glycoproteins and eicosanoids

Back 14

water soluble hormones

Front 15

hormones affect specific

Back 15

target cells

Front 16

specific protein or glycoprotein where the hormones bind on target cells

Back 16

receptor

Front 17

# of receptors =

Back 17

receptor density

Front 18

response to a hormone depends on both the ____ and the ____

Back 18

hormone; target cell

Front 19

action of a lipid soluble hormone

Back 19

make a new protein

Front 20

modifies an inactive protien, does not get inside of cell

Back 20

action of a water soluble protein

Front 21

hormone released from an endocrine gland that circulates in the blood, reaches a target cell, binds to the receptor and brings a specific message to that cell

Back 21

first messenger

Front 22

typical second messenger

Back 22

cylic AMP

Front 23

3 types of hormonal interactions

Back 23

permissive, synergistic, antagonistic

Front 24

2nd hormone strengthens effect of 1st hormone

Back 24

permissive

Front 25
