1203 - ENDOCRINE SYSTEM Flashcards
WHAT IS AN EXOCRINE GLAND
have tubes or ducts that carry the secretion from one gland to another part of the body
WHAT ARE ENDOCRINE GLANDS
secrete hormones that are carried through the blood and lymph
WHAT IS A HORMONE RECEPTOR
engages with hormone and leads to the initiation of downstream signals
WHAT ARE THR 2 MAJOR TYPES OF HORMONES
amino acid derived and lipid derived
WHAT ARE THE ENDOCRINE GLANDS IN YOUR BODY
testes, ovaries, pancreas, adrenal glands, thymus, thyroid gland, parathyroid glands, hypothalamus, pineal gland and pituitary gland
WHAT ARE THE TWO TYPES OF AMINO DERIVED HORMONES
amine and peptide + protein hormones
WHAT HORMONES ARE LIPID DERIVED
steroid hormones
WHAT ARE THE TWO TYPES OF RECEPTORS
intracellular and cell membrane receptors
WHAT ARE INTRACELLULAR RECEPTORS
receptors that are located inside the cell. hormones that bind must be able to cross the bilayer
WHAT IS AN EXAMPLE OF A HORMONE THAT USES INTRACELLULAR RECEPTORS
steroid hormones since they are derived from cholesterol
WHAT ARE CELL MEMBRANE RECEPTORS
located on the surface of the cell. most amino derived hormones bind to cell membrane receptors, causing signaling cascades.
WHAT ARE SIGNALLING CASCADES
a series of sequential activation of enzymes within a cell. this increases the speed, efficiency and specify of the hormone responses
WHAT ARE THE 2 HORMONES RELEASED BY THE THYROID
thyroid hormone and calcitonin
WHAT ARE THE TWO HORMONES RELEASED BY THE PANCREAS
glucagon and insulin
WHAT ARE THE TWO HORMONES RELEASED BY THE ADRENAL MEDULLA
epinephrine and norepinephrine
