A&P CHAPTER 16: ENDOCRINE SYSTEM Flashcards
DOES THE ENDOCRINE SYSTEM WORK SLOWER OF FASTER THAN NERVOUS SYSTEM?
SLOWER
WHAT DOES THE ENDOCRINE SYSTEM SECRETE
HORMONES
PARACRINE VS AUTOCRINE SECRETIONS
PARACRINE: AFFECT ONLY NEIGHBORING CELLS
AUTOCRINE: AFFECT THE SECRETING CELL ONLY
HORMONES
CHEMICAL MESSENGERS THAT DIFFUSE FROM BLOODSTREAM TO ACT ON TARGET CELLS AND REGULATE THEIR METABOLIC FUNCTIONS
STEROID HORMONES DERIVE FROM
CHOLESTEROL
EX. TESTOSTERONE, CORTISOL
AMINES HORMONES DERIVE FROM
AMINO ACIDS
EX. EPI, NOREPI
GLYCOPROTEIN HORMONES DERIVE FROM
CARBS AND PROTEINS
EX: TSH
PEPTIDE HORMONES DERIVE FROM
AMINO ACIDS
EX: OXYTOCIN
PROTEIN HORMONES DERIVE FROM
AMINO ACIDS
EX: GH, PTH
FIRST MESSENGER
HORMONE THAT TRIGGERS ENTERING OF TARGET CELL BY HORMONE
LEUKOTRIENES
RELEASE SIGNALS THAT REGULATE INFLAMMATION AND ALLERGIC REACTIONS
SECOND MESSENGERS
BIOCHEMICALS IN CELL THAT CAUSE CHANGES IN RESPONSE TO THE HORMONES BINDING
MAIN HORMONE THAT STIMULATES CELLULAR METABOLISM
THYROXINE
WHAT MECHANISM CONTROLS HORMONE SECRETION
NEGATIVE FEEDBACK
HUMORAL STIMULI
CHANGING BLOOD LEVELS OF CERTAIN IONS AND NUTRIENTS TRIGGERS ENDOCRINE GLAND ACTIONS
NEURAL STIMULI
ENDOCRINE GLAND STARTS ACTION FROM NERVE FIBER STIMULATION
HORMONAL STIMULI
HORMONE RELEASES DUE TO THE PRODUCTION OF OTHER HORMONES
PERMISSIVENESS HORMONE INTERACTION
ONE HORMONE CANNOT EXERT ITS FULL EFFECTS WITHOUT THE PRESENCE OF ANOTHER HORMONE
SYNERGISM HORMONE INTERACTION
ONE HORMONE PRODUCES THE SAME EFFECT AS ANOTHER HORMONE ON THE TARGET CELL, AMPLIFYING THEIR EFFECTS
ANTAGONSIM HORMONE REACTION
ONE HORMONE OPPOSES ANOTHER HORMONE’S ACTIONS
WHAT DOES THE PITUITARY GLAND DO
MANUFACTURES AND RELEASES A VARIETY OF HORMONES
WHAT DOES THE HYPOTHALAMUS DO FOR THE PITUITARY GLAND
SENDS RELEASING AND INHIBITING HORMONES/STIMULUS TO THE PITUITARY AND REGULATE ITS HORMONE SECRETIONS
WHICH ONE IS THE “MASTER ENDOCRINE GLAND”
ANTERIOR PITUITARY GLAND
