QuestionAnswer
Pro-opiomelanocortin is the precursor for what hormone released from the anterior pituitary?
catalyzes the conversion of progesterone to 11-deoxycorticosterone
True or False: 17 a hydroxylase deficiency causes increased androgens in the blood
Gene responsible for encoding 11B hydrolase
Primary Addison's disease is caused by a deficiency of ____.
gene responsible for encoding 11 B hydroxysteroid dehydrogenase
A baby born with 11B hydroxylase deficiency high or low blood pressure
these 2 enzymes catalze the conversion of pregnenolone to progesterone
Cortisol cause an increase in gluconeogensis and a _____ in glucose uptake.
these 2 enzymes catalze the conversion of pregnenolone to DHEA.
the region of the adrenal cortex that secretes mineralocorticoids
True or False: overstimulation of cortisol can cause diabetes.
what catalyzes the conversion of cholesterol to pregnenolone?
T/F: Adrenal gland size is proportional to the stimulation of the gland.
no steroids are made in this disorder
A baby born with21 hydroxylase deficiency has ___ blood pressure.
responsible for the conversion of corticosterone to aldosterone
ADH (vasopressin) and Corticotropin releasing hormone cause the release of what hormone from the anterior pituitary?
True or False: Cortisol levels generally peak around midnight.
Secondary Addison's disease is caused by a deficiency of ____.
can cause ambiguous genitalia in males and absent puberty in females because androgens are not able to be made. can occur as a result of defective CYP17
True or False: The melanocortin family of receptors are G protein coupled receptors.
True or False: aldosterone synthase deficiency presents with ambiguous genitalia
melanocortin receptor that binds ACTH stimulating steroidogenesis
pregnenolone is converted to progestrone in which organelle of the cell?
True or False: Cortisol decreases red blood cell production.
T/F: Cortisol acts as a negative feedback regulator at the anterior pituitary and hypothalamus
defective gene in lipoid hyperplasia
True or False: 17 a hydroxylase deficiency causes increased blood pressure
QuestionAnswer
the region of the adrenal cortex that secretes glucocorticoids
melanocortin receptor involved in pigmentation
melanocortin receptor involved in anorexia
inactive form of cortisol
True or False: A female baby born with defective CYP21 has increased production of DHEA, causing ambiguous genitalia.
A baby born with 21 hydroxylase deficiency will have _____ mineralocorticoid and glucocorticoid levels.
hormone disorder chasracterized by high levels of ACTH. Patients generally have a redistribution of fat to the truncal areas of the body, with muscle wasting at the extremties
channel responsible for transporting cholesterol into the mitochondria
Cortisol acts to _____ lipolysis.
T/F: Cortisol can only bind the glucocorticoid receptor.
CAH characterized by salt wasting, normal glucocorticoids, normal androgens, and low blood pressure
