Endocrine Anatomy and Physiology Flashcards
(25 cards)
Blood levels of many hormones vary within a narrow range due to , where target organ effects feed back to inhibit further hormone release.
Negative Feedback
The type of hormone interaction of is where more than one hormone produces the same effects at the target cell and their effects together are amplified.
Synergism
The hypothalamic-pituitary-target endocrine organ feedback loop is an example of stimuli.
Hormonal
When insulin binds to its insulin receptor, which is a enzyme, it is activated by autophosphorylation.
Tyrosine Kinase
The pituitary, thyroid, parathyroid, adrenal, and pineal glands are glands.
Endocrine
Because they are , steroid hormones diffuse into target cells to bind and activate intracellular receptors.
Lipid soluble
A stimulus is the type of trigger that causes endocrine glands to secrete hormones in response to hormones produced by other endocrine organs.
Hormonal
The type of hormone interaction of is where one hormone does not have its full effects without the presence of another hormone.
Permissiveness
are amino acids or steroids that increase or decrease the rates of normal cellular processes by acting on their target cells.
Hormones
The type of hormone interaction of is where one hormone opposes the action of another hormone.
Antagonism
-soluble hormones directly activate genes by acting on receptors inside of its target cell.
Lipid
The hypothalamus has neural functions while also producing and releasing hormones, so it is referred to as a organ.
Neuroendocrine
Most amino acid-based hormones, which are water-soluble, generate intracellular when the hormone binds to a receptor in the plasma membrane.
2nd messengers
stimulus is the type of trigger that causes endocrine glands to secrete hormones in response to changing blood levels of certain ions and nutrients.
HUMORAL
In direct gene activation, a receptor-hormone complex binds to a specific region of to prompt DNA transcription to produce a messenger RNA.
DNA
The amine hormones, which are catecholamines and thyroid hormones, are derivatives of the amino acid .
TYROSINE
The endocrine system influences metabolic activity through the secretion of chemical messengers called .
Hormones
The release of parathyroid hormone in response to decreased blood calcium levels is a type of stimulus.
HUMORAL
The release of norepinephrine and epinephrine from the adrenal medulla in response to sympathetic nervous system stimulation is a type of stimuli.
Neural
-soluble hormones act on receptors in the plasma membrane to communicate with its target cell.
Water
A stimulus is the type of trigger that causes endocrine glands to secrete hormones in response to nerve fibers.
Neural
Most hormones are peptides or proteins, and their synthesis is dictated by the messenger ribonucleotide .
mRNA
All steroid hormones are derivatives of .
Cholesterol
Natural hormones are made of cholesterol and are synthesized and secreted by the adrenal cortex, gonads, corpus luteum, and placenta.
Steroid
