Pituitary gland help control the following body processes: Some of the diseases involving the pituitary gland are: All of the functions of the pituitary gland can be adversely affected by an over- or under-production of associated hormones. The pituitary gland is important for mediating the stress response, via the hypothalamic–pituitary–adrenal axis (HPA axis) Critically, pituitary gland growth during adolescence can be altered by early life stress such as childhood maltreatment or maternal dysphoric behavior. It has been demonstrated that, after controlling for age, sex, and BMI, larger quantities of DHEA and DHEA-S tended to be linked to larger pituitary volume. Additionally, a
Brain-to-body mass ratio have spinal cords, or in some cases, central nervous systems. Recent research indicates that, in non-human primates, whole brain size is a better measure of cognitive abilities than brain-to-body mass ratio. The total weight of the species is greater than the predicted sample only if the frontal lobe is adjusted for spatial relation. The brain-to-body mass ratio was however found to be an excellent predictor of variation in problem solving abilities among carnivoran mammals. In humans, the brain to body weight ratio can vary greatly from person to person; it would be much higher in an underweight person than an
