Document Summary
Transitional stage of physical and mental development between childhood and adulthood. Begins at physical change and ends when growth stops (adulthood) Begins at physical change ends then person is capable of reproduction. Growth hormone: gh plays an important role in structural changes associated with adolescent growth spurt, gh also stimulates production of insulin like growth factor (igf) by liver. Igf plays a role in structural changes and also has been linked to adolescent neural changes. Bone growth, changes in height, adiposity, muscle growth, change in weight, heart and lung function, neural changes. Two skeletal growth spurts: infancy (cartilage to bone), adolescence (longitudinal growth at epiphyseal plate) Males typically end up taller and peaks later on. Male growth spurt begins later, accelerates more slowly and lasts longer before epiphyses fuse as males have lower leves of oestrogen and slower progression to completion. Female has 50% more body fat than males. It accumulates in breasts, hips, buttocks, thighs and upper arms.
