- The system plays a vital role in orchestrating cellular
interactions, metabolism, growth, reproduction, aging, and response to ad- verse conditions.
Answer
endocrine
- The endocrine system involves the release of chemical transmitter sub- stances known
as .
Answer
hormones
- Most hormones secreted from endocrine glands are released directly into the .
Answer
bloodstream
- To prevent accumulation, hormones must be inactivated by a
system so that when the hormone concentration in- creases, further production of that hormone is in inhibited.
Answer
negative feedback
- Some hormones act locally in the area where they are released; this is called
. 1 / 4
Answer
paracrine action
- What is an abnormal protrusion of one or both eyeballs?
Answer
exophtalmos
- What determine the levels of circulating hormones, the presence of autoan- tibodies, and the
effect of a specific hormone on other substances?
Answer
blood tests
- What are used to measure the amount of hormones or the end products of hormones
excreted by the kidneys?
Answer
urine tests
- What tests are used to confirm hypofunction of an endocrine organ? The tests determine
how an endocrine gland responds to the administration of stimulating hormones that are normally produced or released by the hypo- thalamus or pituitary gland?
Answer
stimulation
- What tests are used to detect hyperfunction of an endocrine organ? They determine if the
organ is not responding to the negative feedback mechanisms that normally control the secretion of hormones from the hypothalamus or pituitary gland. 2 / 4
Answer
suppression
- The gland, or hypophysis, is commonly referred to as
the master gland because of the influence it has on the secretion of hormones by other endocrine glands.
Answer
pituitary

Answer
FSH, LH, prolacting, ACTH, TSH, GH
- What is the most abundant anterior pituitary gland hormone, regulates growth in
children and energy and metabolism in adults?
Answer
GH
- What are the important hormones secreted by the posterior lobe of the pituitary
gland?
Answer
vasopressin (ADH), oxytocin
- What controls the excretion of water by the kidney; its secretion is stimu- lated by an
increase in the osmolality of the blood or by a decrease in blood pressure?
Answer 3 / 4
vasopressin (ADH)
- What is stimulated during pregnancy and at childbirth; it facilitates milk ejection during
lactation and increases the force of uterine contractions dur- ing labor and delivery?
Answer
oxytocin
- Over secretion of the anterior pituitary gland most commonly involves ACTH or GH
and results in or .
Answer

- What is a disorder caused by an excess of GH in adults, results in en- largement of
peripheral body parts and soft tissue; after the fusion of the epiphyseal plats has occurred without an increase in height?
