uses epinephrine and norepinephrine as chemical messengers
relies primarily on negative feedback mechanisms
effective in coordinating cell, tissue, and organ activities on a sustained, long-term basis
relies on release of chemicals that bind to specific receptors
Hypothalamic neurons synthesize hormones like ADH that increase the elimination of water from the body
It secretes regulatory hormones that influence endocrine cells in the anterior pituitary gland
All of the above are correct
It has autonomic centers that exert direct neural control over endocrine cells of the adrenal cortex
They are also called biogenic amines and are synthesized from tyrosine
They are chains of amino acids such as glycoproteins, small proteins, or polypeptides
They are synthesized by ribosomes and are lipophilic
They are derivatives of arachidonic acid
ensures that RH from the hypothalamus synthesizes the correct amount of a specific hormone
provides efficient means of ensuring that all hypothalamic hormones will reach target cells in the adenohypophysis before being diluted in general circulation
ensures that all hormones destined for the pituitary are diluted in general circulation before entering the adenohypophysis
None of the above is correct
It stimulates smooth muscle contraction in the ductus deferens and prostate gland
It stimulates production of sex hormones
It stimulates the breakdown of stored triglycerides by adipocytes
It stimulates nurse cells, which then promote the maturation of sperm
More ADH is released to increase the solute concentration of blood and urine
It does not change at all
ADH secretion is inhibited by drinking alcohol
ADH secretion increases causing vasoconstriction and increased blood pressure
ACTH participates in a negative feedback loop with cortisol
The cortisol acts synergistically with other hormones
High levels of cortisol stimulate other steroid hormones to be released
CRH from the hypothalamus inhibits ACTH release
F cells / a hormone identical to growth hormone–inhibiting hormone
beta cells / insulin
delta cells / glucagon
alpha cells / pancreatic polypeptide
It promotes protein synthesis.
It will facilitate the transport and utilization of glucose by cells.
Both A and B are functions of insulin.
It will decrease storage of glucagon in the cell
stimulation of amino acid absorption and protein synthesis
breakdown of triglycerides in adipose tissue
accelerated glucose uptake and utilization
stimulation of glycogen formation
pancreas and adrenal cortex; produce insulin
liver; produce glucose
brain, kidneys, and digestive tract; absorb glucose without insulin stimulation
liver; produce glucagon
A and B are correct.
Glucose is lost in the urine, which increases blood volume.
Less water is reclaimed by osmosis in the kidneys.
Water loss reduces blood volume, promoting secretion of ADH
