BIOD 151 MODULE 6 - ENDOCRINE SYSTEM
WITH VERIFIED QUESTIONS AND ANSWERS
100%.
endocrine system - CORRECT ANSWER-the body's "slow" chemical communication system; a set of
glands that secrete hormones into the bloodstream
environment, blood substances, metabolism/growth, immune response, sexual development
nervous vs. endocrine system - CORRECT ANSWER-endocrine
1. speed = slower
2. release = hormones
3. release into = bloodstream, eventually reaches target cells
nervous
1. speed = faster
2. release = neurotransmitters
3. release into = other neurons, glands, muscles
hormone - CORRECT ANSWER-organic chemical produced by 1 set of cells that affects a different set of
cells
1. specific organ of origin
2. specific target organ
3. specific action
lock-and-key mechanism - CORRECT ANSWER-each hormone can fit in 1 specific receptor
"unlocks" cell and can change cell activity
, 2 types of hormones - CORRECT ANSWER-1. peptide
2. steroid
peptide vs steroid hormones - CORRECT ANSWER-peptide
1. derived from = proteins, catecholamines, peptides
2. activation = existing enzymes, inside the cell (attach to outside)
3. action = quickly, short period of time
steroid
1. derived from = cholesterol
2. activation = enters nucleus to alter protein synthesis
3. action = slower action, longer period of time
types of glands - CORRECT ANSWER-1. exocrine
2. endocrine
endocrine vs exocrine glands - CORRECT ANSWER-endocrine glands
1. ductless
2. secrete into bloodstream
3. distribution to body
exocrine glands
1. ducts
2. secrete into epithelial tissue (parotid glands in cheeks - secrete via duct into mouth)
primary endocrine organs - CORRECT ANSWER-1. hypothalamus
2. pineal gland (back)
3. pituitary (anterior/posterior)
