Endocrine Response to Resistance Exercise Flashcards
Hormones
chemical messengers that are synthesized, stored, and released, into the blood by endocrine glands
Endocrine Glands
body structures specialized for secretion
Neuroendocrinology
study of the interactions between the nervous system and the endocrine system
Steroid Hormones
have hormone-specific receptors located in nucleus
Thyroid Hormones
have hormone-specific receptors located in nucleus
Target Tissue
cells for which hormones are targeted
Myosin Heavy-Chain (MHC) Proteins
motor protein of muscle thick filaments
Anabolic Hormones
hormones that promote tissue building: insulin, IGF, testosterone, GH
Catabolic Hormones
hormones that degrade cell proteins to support glucose synthesis; corisol, progesterone
Lock-and-Key Theory
a given hormone interact with a specific receptor
Cross-Reactivity
a given receptor partially interacts with hormones that are not specifcally designed for it
Allosteric Binding Sites
sites where substances other than hormones can enhance or reduce the cellular response to the primary hormone
Downregulation
when a receptor becomes nonresponsive to a specific hormone, preventing it from stimulating the protein synthesis response in the cell
Hormone-Receptor Complex (H-RC)
forms after hormone bind with receptors; causes conformational shift in receptors and activates it
Polypeptide Hormones
hormones made up of amino acids
