APHY 201 Ch 7, 23 Endocrine System Ivy Tech Questions with Correct
Answers
Question 1:
1. control reproduction, development and growth
Answer:
Functions of the endocrine system
Question 2:
7. Regulation of the internal environment characteristics of the endocrine system through
blood and lymphatic vessels. hormones
Answer:
of proteins, enzyme functions, cellular secretions, rate of cell reproduction.
includes cells, tissues, and organs that secrete hormones. These organs and tissues are
scattered in different regions of the body. Endocrine glands have no ducts so hormones are
transported

,Question 4:
Factors that affect target cell activation?
Answer:
tissues with receptors for a specific hormone
Question 5:
How are hormones specific?
on/in its target cell. Hormone binds to proper receptor like a key in a lock. exocrine glands
-have ducts to transport their secretion
-action: extra cellular effect (enzyme on food)
Answer:
Affinity of binding between receptor and hormone
act on specific target cells/target organs because each hormone binds to protein receptors
present
Question 6:
-release secretion into blood or lymph vessels to travel to target cells and induce an action:
intracellular effect.
Major endocrine organs
Answer:
endocrine glands
hypothalamus (neuro-endocrine gland), pituitary gland, thyroid gland, parathyroid gland,
adrenal
Question 7:
Other organs contain cells or tissues that secrete hormones
-liver (IGF)
-small intestine- (secretin, CCK)
-placenta (estrogen, progesterone, hCG)
-stomach (gastrin)
-kidneys (EPO, renin, vitamin D)
-heart (ANP)
-adipose (leptin)
Answer:
gland, pineal gland, thymus gland, pancreas, ovaries and testes
-all steroid hormones are derived from cholesterol and are lipid soluble. Ex. estrogen,
-contain amino acids, protein or glycoprotein. All are water soluble except for thyroid hormone.

Steroid hormonesprogesterone, testosterone, cortisol, aldosterone Amino acid-based
hormonesEx. insulin, glucagon, calcitonin, GH, PRL. peptide hormoneshormones composed of
short chains of amino acids Catecholaminesresponse

stressSteroid hormonesprogesterone, testosterone, cortisol, aldosterone Amino acid-based

Question 9:
Amino acid-based hormones use second messenger systems
Answer:
dopamine, norepinephrine, epinephrine
-hormone does not enter the cell but binds to a plasma membrane receptor to initiate a second
messenger system that causes enzyme activation, secretory function, and/or permeability
