c. decreases calcium absorption from the gut
d. demineralizes bone and raises blood calcium levels
A hypodermic injectionof epinphrine would
a. increase heart rate, increase blood pressure, dilate the bronchi of the lungs, and increase peristalis
b. decrease heart rate, decrease blood pressure, constrict the bronchi, and increase peristalsis
c. decrease heart rate, increase blood pressure, constrict the bronchi, and decrease peristalis
d. increase heart rate, increase blood pressure, dilate the bronchi, and decrease peristalsis
Testosterone is to the male as which hormone is to the female?
a. luteinizing hormone
If anterior pituitary secretion is deficient in a growing child, the child will
a. develop acromegaly
b. become a dwarf but have fairly normal body proportions
c. mature sexually at an earlier than normal age
d. be in constant danger of becoming dehydrated
If there is adequate carbohydrate intake, secretion of insulin results in
a. lower blood glucose levels
b. increased cell utilization of glucose
c. storage of glycogen
d. all of these
a. are produced by exocrine glands
b. carried to all parts of the body in blood
c. remain at constant concentration in the blood
d. affect only non-hormone-producing organs
Some hormones act by
a. increasing the synthesis of enzymes
b. converting an inactive enzyme into an active enzyme
c. affecting only specific target organs
d. all of these
Absence of thyroid hormone would result in
a. increased heart rate and increased force of heart contraction
b. depression of the CNS and lethargy
d. high metabolic rate
Medullary chromaffin cells are found in the
a. parathyroid gland
b. anterior pituitary gland
c. adrenal gland
d. pineal gland
Atrial natriuretic peptide secreted by the heart has exactly the opposite function of this hormone secreted by the zona glmerulosa
a. antidiurectic hormone
Which type of hormone receptor-plasma membrane bound or intracellular - would be expected to provide the most long-lived response to hormone binding and why?
Name two endocrine glands (or regions) that are important in the stress response, and explain why they are important.
The anterior pituitary is often referred to as the master endocrine organ, but it, too has a "master."
What controls the release of anterior pituitary hormones?
Endemic goiter is not really the result of a malfunctioing thyroid gland. What does cause it?
List some problems that elderly people might have as a result of decreasing hormone production.
We have a new patient to consider today. Mr. Gutterman, a 70-year-old male, was brought into the ER in a comatose state and has yet to come out of it. It is obvious that he suffered severe head trauma-- his scalp was badly lacerated, and he has an impated skul fracture. His initial lab tests (blood and urine) were within normal limits. His fracture was repaired and the folloing orders and others were given:
Check qh and record: spontaeous behavior, level of responsiveness, movements, pupil size and reaction to light, speech, and vital signs.
Turn patient q4h and maintain meticulous skin care and dryenss.
He is unconscious, the level of damage to his brain is unclear. Monitoring his responses and vital signs qh will provide information for his care providers about the extent of his injuries.
Turning q4h and providing careful skin care will prevent Decubs as well as stimulating his proprioceptive pathways.
On the second day of his hospitalization, the aide reports that Mr. Gutterman is breathing irregularly, his skin is dry and flaccid, and that she has emptied his urine reservoir several times during the day. Upon receiving this information, the MD ordered:
blood and urine tests for presence of glucose and ketones
Mr. Gutteman is found to be losing huge amounts of water in urine and the volume lost is being routinely replaced via IV line. Mr. Gutteman's blood and urine tests are negative for glucose and ketones.
What would you say Mr. Gutteman's hormonal problem is and what do you think caused it?
Ist life threatening?
His condition is termed diabetes insipidus, a condition in which insufficient quantities of antidiuretic hormone (ADH) are produced or released.
These types of patients excrete large volumes of urine but do not have glucose or ketones present in the urine.
The head trauma could have damaged his hypothalamus, chich produces the hormone, or injured his posterior pituitary gland, which produces the hormone, or injured his posterior pituitary gland.
Which releases ADH into the bloodstream.
It is not life threatening for most pple with normal thirst mechanism. However, he is unable to tell or preform the skill on his own, and to prevent dehydration on it's own.
