In early pregnancy levels are expected to rise to double every 2-3 days.

structyrally related to oxytocin

initially produced by trophoblast cells of embryo

higher levels seen in multiple gestation.

Q 11. Patient with 24 weeks gestation and history of hypothyroidism on treatment.thyroid profile done will reveal

Free T3 and T4 levels are low even in the absence of hypothyroidism.

thyroid binding globulin is elevated therefore total T3 and T4 levels are low.

Free T3 and T4 levels are normal.

TSH levels increase in response to increase prolactin.

Q 12. all contribute to immune tolerance of fetal allograft except

Elevated progesterone and prolactin acts as immunosuppression

Villous cytotrophoblast cell of the placenta do not express MHC class I and MHC class II transplantation antigen on their surfaces.

p lacental tissue may have altered metabolic process that promote immunosuppression.

large no. of fetal blood cells are actively transported into the maternal circulation Provoking tolerance.

chorion

amnion

decidua

cotyledon

Q 14. correct order during phases of sexual response cycle

exual attraction or arousalexcitement phasepleatue phaseorgasmresolution phase

sexual attraction or arousal pleatue phaseorgasmexcitement phase resolution phase

sexual attraction or arousal pleatue phase excitement phase orgasmresolution phase

sexual attraction or arousalresolution phaseexcitement phasepleatue phaseorgasm

Q 15. regarding transport of molecules between maternal circulation and placenta false statement include

respiratory gases are transported by passive diffusion.

IgG binds a membrane receptor and enters via endocytosis.

calcium transport through active diffusion.

glucose bound to membrane receptors and enter s placental tissue by endocytosis.

IL-1

IL-2

IL-3

IL-4

Q 17. which the following structure develop into the placenta

Trophoectoderm

blastocyst inner cell mass

decidua

apposition

adhesion

invasion

all

men achieve erection after spinal cord transection.

short stage of refractoriness during primary stage of resolution

sufficient stimulation can induce orgasm in female at any point during resolution phase.

Q 20. sexual response is most individually, socially and cultured derived in phase

sexual attraction or arousal

resolution phase

excitement phase

pleatue phase

Q 21. quantitative hcg measured for pregnancy secreted by

fetal pituitary gland

developing trophoblast

corpus luteum

maternal pituitary gland

Q 22. LH surge is primarily responsible for

apoptosis

endometrial sloughing

decrease in PGF 2 alpha

ovulation

Q 23. incorrect statement include

deviation from the typical 28 day menstrual cycle typically occurs because of different lengths in the follicular phase.

Although one oocyte typically ovulated per cycle several will begin their development.

prolonged elevations in progesterone levels trigger the LH surge.
