what is the chemical component of Steroid hormones
a. protein
b. cholesterol
c. carbohydrates
d. amino acids
chemical component of :
> Steroid hormones - Cholesterol
> proteins - protein
> Amine hormones - Amino acid
which of the following hormones has a site of production has a Thyroid glands and adrenal glands
a. steroid
b, protein
c. amine
Site of production of
> Steroid hormones - Adrenal glands , gonads and placenta
> proteins - (3P) anterior Pituitary , Placenta and Parathyroid glands
> Amine hormones - Thyroid and Adrenal glands
which of the following hormones is soluble to lipid
a. steroid
b, protein
c. amine
soluble at
> Steroid hormones - lipids
> proteins - water
> Amine hormones - water
deficiency of Growth Hormone
a. Dwarfism
b. Gigantism
c. acromegaly
d. aota
Dwarfism
- children with pituitary dwarfism - DEFICIENCY OF GH
Acromegaly and gigantism
- overproduction of GH
which of the following test is gold standard screening for GH deficiency
a. OGTT
b. insulin tolerance test
c. arginine stimulation test
d. somatostatin C
test for GH
I. GH deficiency test
a. insulin tolerance test - Gold standard screening test
b. arginine stimulation test - 2nd confirmatory
II. screening for Acromegaly
somatomedin C or insulin like Growth factor -1 (IGF-1)
increase IGF-1 - ACROMEGALY
decrease IGF-1 - GH deficiency
IIi. Confirmatory
OGTT
important markers in diagnosing fertility and menstrual cycle disorders
a. GH
b. TSH
c. FH
d. LH
follicle stimulating hormone (FSH) and luteinizing hormone (LH)
- important markers in diagnosing fertility and menstrual cycle disorders
maturation of follicles, ovulation , production of estrogen, progesterone, testosterone
a. GH
b. TSH
c. FSH
d. LH
Luteinizing hormone (LH)
production of sperm and egg
a. GH
b. TSH
c. FSH
d. LH
Follicle stimulating hormone (FSH)
elevation of FSH is due to
a. lack of estrogen
b. overproduction of estrogen
c. premature menopause
d. nota
elevation of FSH is a clue in diagnosing PREMATURE MENOPAUSE
increased FSH and LH after menstrution is due to LACK OF ESTROGEN
production of adrenocortical hormones by adrenal cortex
a. ACTH
b. TSH
c. FSH
d. LH
adrenocorticotropic hormone (ACTH)
action :
production of adrenocortical hormones by adrenal cortex
Diurnal variation :
highest levels in early am (6-8AM)
lowest in the late afternoon (6-11 PM)
specimen should not be allowed to have contact with GLASS because ACTH adheres glasssurface = decrease ACTH
stress hormone
a. LH
b. ACTH
c. PRL
d. TSHp
Prolactin
- it is a PITUITARY LACTOGENIC HORMONE, STRESS HORMONE AND DIRECT EFECTOR HORMONE
