BPK 105 module 5 Exam Questions
with Correct Answers
What does the adrenal medulla secrete - Answer- epinephrine and norepinephrine
What does the pineal gland secrete - Answer- melatonin
Do lipid soluble hormones act slowly or rapidly - Answer- rapidly
Are membrane bound receptors on the inside out outside of the cell - Answer- outside
on the membrane
The combination of the hormone and its receptor form a - Answer- transcription factor
What are the two types of receptor classes - Answer- nuclear receptors
membrane bound receptors
Endocrine glands - Answer- Glands of the endocrine system that release hormones into
the bloodstream
Hormones circulate through the bloodstream to specific sites called - Answer- target
tissues/ effectors
Exocrine glands - Answer- secrete chemical substances into ducts that lead either to
other organs or out of the body
Chemical messengers - Answer- allow cells to communicate with each other to regulate
body activities
Autocrine chemical messengers - Answer- released by cells and have a local effect on
same cell type from which chemical signals released; e.g., prostaglandin
Paracrine chemical messengers - Answer- released by cells and affect other cell types
locally without being transported in blood
somatostatin
neutrotransmitters - Answer- a chemical messenger that carries impulses across the
synaptic gaps between neurons
, ach NE
Endocrine chemical messengers - Answer- Secreted into the blood by specialized cells;
travels some distance to target tissues; results in coordinated regulation of cell function
insulin, thyroid hormone, growth hormone
hormones of the endocrine system are secreted in response to - Answer- humoral
neural or hormonal stimulus
main regulatory functions of the endocrine system 10 - Answer- regulation of
metabolism
control of food intake and idegestion
modulation of tissue development
reguation of ion levels
control of water balance
regulation of CV functions
control of blood glucose and other nturients
control of reproductive functions
stimulation of uterine contractions and milk release
modulation of immune system function
there are two types of chemical categories of hormones - Answer- lipid soulble and
water soluble
steroid hormones - Answer- Derived from cholesterol, lipid-soluble.
lipid soluble hormones - Answer- non polar and include steroid thyroid and fatty acid
dereivitive hormones
how do lipid soluble hormones get transported - Answer- they bind to binding proteins
and travel in the bloodstream
water soluble hormones - Answer- polar molecules that include protein hormones
peptide hormones
water soluble hormones can/cnat dissolve in the blood - Answer- can
therefor theycan deliver to target tissues without attaching to a binding protein
short lifespan compared to lipid soluble hormones
there are some water soluble hormones that have modifications to them these
modifications are: - Answer- having a carbohydrate attached to them
terminal end protected by protesase activity
