-The amnion is a tough, thin membrane that surrounds a developing fetus in mammals, reptiles, and birds. It is the first of the three cavities (amnion, chorion and yolk sac) in the embryo and is formed on 8 dpc.
-In the human body, the amnion is the first of three cavities, including the chorion and yolk sac, that work together to keep the developing fetus nourished and protected.
-The amnion provides a protective environment in which the fetus' temperature is regulated and protects the fetus from friction caused by the mother's movements.
Different substances such as growth factors and nutrients affect the mechanism of density-dependent inhibition of growth as cells become more and more numerous
Generally the low pitched sound vibrates the basilar membrane close to its apex while high pitched sound vibrates the basilar membrane close to its base
Brain receives information at temporal lobe. Thus, high and low pitched sounds are received at the higher and lower part of the temporal lobe.
