Ch. 3 Endocrine Responses to Resistance Exercises Flashcards
hormones
chemical messengers that are synthesized, stored, and released into the blood by endocrine glands and certain other celss
endocrine glands
body structures specialized for secretion
neuroendocrinology
refers to the study of the interactions between the nervous system and the endocrine system
anabolic hormones
hormones that promote tissue building
catabolic hormones
attempt to degrade cell proteins to support glucose synthesis
lock-and-key theory
where the hormone receptor is the lock and the hormone the key
cross-reactivity
where a given receptor partially interacts with hormones that are not specifically designed for it
allosteric binding sites
where substances other than hormones can enhance or reduce the cellular response to the primary hormone
downregulation
the inability of a hormone to interact with a receptor
hormone-receptor complex (H-RC)
formed when the hormone binds with its receptor inside the cell causing a conformation shift in the receptor and activating it
polypeptide hormone
made up of amino acids, like growth hormone and insulin
secondary messengers (STAT)
bring messages from polypeptide hormones across the cell membrane
diurnal variations
normal fluctuations in hormone levels throughout the day
