Endocrine Responses to PT Flashcards
general adaptation syndrome
refers to how the adrenal gland responds to a noxious stimulus (stressor)
hormones
chemical messengers or signal molecules that are synthesized, stored, and released into the body by endocrine glands
endocrine gland
body structures that are specialized for the transportation of hormones
neuro endocrinology
the study between the interactions of the nervous system and the endocrine system
neuroendocrine immunology
the study of the connection between the neural, endocrine, and immune system
anabolic hormones
hormones that promote tissue building
hormones that promote tissue building
insulin, insulin-like growth factors (IFGs), testosterone, and growth hormone
catabolic hormones
progesterone and cortisol can degrade cell proteins
lock and key theory
on of the basic principles of endocrinology is that a given hormone interacts with a specific receptor
cross-reactivity
a given receptor partially interacts w other hormones
allosteric binding sites
substances other than hormones can enhance or defuse the cellular response to the primary hormone
downregulation
the inability of a hormone to interact with a receptor
hormone-receptor complex (H-RC)
this forms when hormone binds with its receptor after diffusing across the sarcolemma - this causes a shift in the the receptor and thus activating it
diurnal variations
normal fluctuations in hormone levels throughout the day
