BMS 300 ACTUAL TEST FULL QUESTIONS
AND CORRECT ANSWERS EXAMPREP
STUDY SHEET
●● endocrinology
Answer: study of hormones and endocrine organs
●● Exocrine glands
Answer: release contents through a duct that leads to epithelial surface
●● merocrine
Answer: part - release by exocytosis (sweat and salivary glands)
●● apocrine
Answer: away - release by part of the cells is pinched off (mammary and
odorous sweat glands)
●● holocrine
Answer: whole - release by entire cell rupturing (sebaceous glands)
●● 3 classes of hormones
Answer: amino acid derivatives
,peptide hormones
lipid derivatives
●● Amino Acid Derivatives
Answer: derivatives of tyrosine and tryptophan
●● Amino acid derivative examples
Answer: thyroid hormones, catecholamines, serotonin and melatonin
●● Catecholamine examples
Answer: epinephrine, norepinephrine, and dopamine
●● Peptide Hormones
Answer: chains of amino acids; most are synthesized as prohormones
●● Glycoproteins
Answer: proteins more than 200 amino acids long that have
carbohydrate side chains (TSH, LH, FSH); type of peptide hormone
●● Lipid Derivatives
Answer: steroid hormones; bound to specific transport proteins int he
plasma
, ●● Steroid hormones
Answer: androgens from testes, estrogens and progesterone from
ovaries, corticosteroids from adrenal cortex, calcitriol from kidneys
●● Not lipid soluble hormones exp
Answer: catecholamines and peptide hormones
●● non lipid soluble hormones
Answer: unable to penetrate plasma membrane, bind to receptor proteins
on outer surface of plasma membrane
●● Lipid Soluble hormones (exps)
Answer: steroid and thyroid hormones
●● lipid soluble hormones
Answer: diffuse across plasma membrane and bind to receptors inside
cell
●● G protein coupled receptors
Answer: A signal receptor protein in the plasma membrane that responds
to the binding of a signaling molecule by activating a G protein.
●● Secondary messenger effects
