Endocrinology (1A) Flashcards
(16 cards)
Endocrinology involves study of
Biosynthesis, storage, chemistry and physiological function from hormones secreted from endocrine glands or other tissues that secrete them
Endocrinology also is the study of
Hormones, their intracellular signaling pathway they invoke
An endocrine gland lacks a
Duct system
An exocrine gland is one which has a
Duct system
Examples or exocrine and endocrine structure:
Endocrine - thyroid
Exocrine - salivary gland
Some glands like ___ have both endocrine and exocrine.
Pancreas
Multicellular organism coordinate activity between ___ of cells that requires (2):
groups, coordination, communication
The signal cell is responsible for ___ secretion and the target cell receives the message via ____ messengers.
Hormone, extracellular
Endocrine:
Hormone passes through the bloodstream and passes to the target cell
Neuroendocrine:
Carried by blood and functions in conjunction with the nervous system; in the pituitary and hypothalamus
Paracrine:
The target cells are very nearby and it does not need to be taken far, close to the vicinity
Autocrine:
Cell produces hormone into the interstitial space and affect the same cell
Endocrine processes include production of hormones that are secreted into the ___ and travel over ___ distances and is ___ in response depending on the nature of the hormone/ intracellular pathways.
Multiple target cells will occur with some ___.
bloodstream, long, slow, specificity
Paracrine signaling includes neurotransmitters released by ___ and acts locally in a ___ distance. It is ___ acting and more target specific than ____.
diffusion, short, fast, endocrine
Control systems exist and are ___ from cell to cell.
variable
Endocrine hormones are considered based on (6):
Synthesis
Location
Storage/release
Detection on receptors
Signal transduction/amplification
Changes in cellular response of target cell
