The pituitary gland is often thought of as the master endocrine gland because of its regulatory role over other endocrine glands. make an argument in favor of designating the hypothalamus as the master endocrine gland instead of the pituitary gland. use specific examples of endocrine pathways to show how the hypothalamus interacts with the anterior and posterior lobes of the pituitary gland in a regulatory manner. also describe the physical structures through which the hypothalamus communicates with each lobe.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
