Well although our ICSE papers are concentrated on application but i dont think under any dooms' day will such a question pose a problem to us because papers are set for average students
( not intended to call anyone average Crying or Very sad )
.... rather a person who scores average .... so papers are supposed to be easy! study well score good nd then relax! cheers

cretinism->thyroxine
sebum:
A thick substance that is secreted by
sebaceous glands that consists of fat and cellular debris.

The sperm secretes an enzyme hyalurodinase..it facilitates the entry of sperm into the egg by dissolving the wall of the ovum

e ii ovary-> egg-> oviduct-> uterus
e iii motor nerve-> ventral nerve-> sensory nerve->effector
e iv hypothalamus->pituitary->thyroid->thyroxine

nd ur always welcome
