1

the endocrine system is the ________ system of the body

hormonal

2

_____ are chemical messengers

hormones

3

hormones are released in one tissue and transported via the _______ to reach specific cells in other tissues

blood stream

4

each hormone has a ______ on which it acts

specific target cell

5

hormones are effective in coordinating:

cell, tissue, and organ activites on a long term sustained basis

6

hormones are messengers that will cause a cell to change or alter its

function to cause a specific response in the body

7

how do hormones alter cellular operations

changing the types, activites, or quantities of important enzymes and structural proteins

8

hormone release occurs where

capillaries are abundant and allow the hormone to enter the blood stream quickly

9

when in the blood stream hormones are either

free flowing or bound to carrier proteins

10

when _______ reach target cells they do not pass through the cell membrane

non-steroidal

11

what hormones are not soluble in cell membrane

non-steroidal

12

hormones bind to what on the cell membrane

receptors

13

non-steroidal hormones after binding to the receptor on the cell membrane do what

activate messengers in the cytoplasm

14

the activated messengers in the cytoplasm of the cell do what

cause a change in the cell's metabolism or function

15

what is the first messenger

non-steroidal hormone

16

what is the second messenger

cytoplasm of cell

17

steroidal hormone are able to pass through

lipid bilayer of the cell membrane into the cytoplasm

18

which type of hormone directly affects the function of the genes in the nucleus

steroidal
