APHY 201 Module 14 Endocrine System Ivy Tech Questions with Correct
Answers
Question 1:
Study of hormones and endocrine organs
Answer:
....endocrinology
Question 2:
6. increase or decrease cellular activity by changing: plasma membrane permeability, synthesis
of proteins, enzyme functions, cellular secretions, rate of cell reproduction.
endocrine system
Answer:
....functions of the
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 through
Question 3:
blood and lymphatic vessels.
Answer:
....characteristics of the endocrine system
chemical messengers produced by endocrine tissues and released into the blood to alter the
function of
Question 4:
target cells
Answer:
....hormones
chemical messenger for intercellular signalling produced by a secretory cell and released into
interstitial
Question 5:
fluid to engage receptors on adjacent cells.
Answer:
....paracrines
,Question 6:
tissues with receptors for specific hormone
Answer:
....target cells
act on specific target cells/target organs because each hormone binds to protein receptors
present
Question 7:
on/in its target cell. Hormone binds to proper receptor like a key in a lock.
Answer:
....How are hormones
Question 8:
specific?
-have ducts to transport their secretion
-action: extra cellular effect (enzyme on food)
Answer:
....exocrine glands
-release secretion into blood or lymph vessels to travel to target cells and induce an action:
intracellular
Question 9:
effect.
Answer:
....endocrine glands
hypothalamus (neuro-endocrine gland), pituitary gland, thyroid gland, parathyroid gland,
adrenal gland,
Question 10:
pineal gland, thymus gland, pancreas, ovaries and testes
-liver (IGF)
-small intestine- (secretin, CCK)
-placenta (estrogen, progesterone, hCG)
-stomach (gastrin)
-kidneys (EPO, renin, vitamin D)
Answer:
....Major endocrine organs
-heart (ANP)
, Question 11:
-adipose (leptin)
Answer:
....Other organs contain cells or tissues that secrete hormones
-all steroid hormones are derived from cholesterol and are lipid soluble. Ex. estrogen,
progesterone,
Question 12:
testosterone, cortisol, aldosterone
Answer:
....Steroid hormones
-contain amino acids, protein or glycoprotein. All are water soluble except for thyroid hormone.
Ex.
Question 13:
insulin, glucagon, calcitonin, GH, PRL.
....Amino acid-based hormones use second messenger systems
Answer:
....Amino acid-based hormones
-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
changes. -
-hormone enters the cell, gain access to the nucleus of the cell and bind to intracellular
receptors to
Question 14:
alter the production of specific proteins
Answer:
....Steroid hormones and thyroid hormone (T3/T4) use direct
Question 15:
All the amino acid-based hormones except thyroid hormone (t3/T4). Use second-messenger
systems to
Answer:
activation of genes in the nucleus
