Can birth control pills cause you to gain weigh and how soon?
Anawer. Yes, some birth control pills are known to have that sideffect and another commen sideffect is missing periods.. It must have something to do with the hormones in the pills. (technicaly birth control pills are steroids cause of the hormoes and they are known to have some of the same sideffects) But when it happens -if it happens, you cant be sure, but dont worry you will not suddenly get round like a ball.
How protein and amino acid hormones react with a target cell?
The main difference between the two is that one is hydrophilic and the other is hydrophobic. This means that amino acid (peptide) hormoes cannot travel across the cellular membrane to activate genes; they must bind to receptors on the surface and activate second messenger systems. Steroid hormones, on the other hand, can travel right across membranes and affect genes directly.
Why is pituitary glands called master glands?
The Pituitary gland IS called the Master gland because it is the only gland of the endocrine system or the gland system that has an effect on other glands. It is situated at the base of the brain and is divided into three sections. The anterior pituitary, the intermediate pituitary and the posterior pituitary. The pituitary gland has an effect on the other glands in the body and controls their secretion of hormones. For instance, the anterior pituitary gland produces ACTH or adrenocorticotrophic hormone which affects the amount of corticosteroid hormone the adrenal gland secretes. The pituitary gland also produces adh or anti diuretic hormone which controls our fluid balance. This is affected by alcohol and when we have a drink it is responsible for our frequent visits to the toilet and our subsequent dehydration the next morning. The pituitary secretes growth hormone and an over-secretion of this leads to gigantism. Remember the Jaws character in the Bond movies with the steel teeth, he has gigantism. An under secretion of growth hormone leads to the opposite of Jaws and the result is dwarfism. Remember the Ompa-lumpas in Willie Wonkas Chocolate Factory?. Sorry to go on. Hope this helps.
