Document Summary
The uniqueness of adolescence: developmental progression occurs more rapidly in adolescents than in adults. Puberty and physiological development during adolescence: there are several major physiological changes that occur during adolescence, development of both primary and secondary sexual characteristics. Increased endocrine activity particularly in the hpa and hpg axes: the hypothalamus regulates the pituitary which controls hormone levels in the body, physical growth and body composition changes (e. g. height and weight changes, fat and muscle distribution) Increases in strength and physical endurance due to growth in cardiovascular and pulmonary. Puberty and hormones: hormones have two different functions: organizational and activating, hormones are present pre and post-natally, these hormones direct or organize development of neurological and anatomical structures, activational hormones initiate puberty. The hpa axis: the hpa is also activated; stimulating the adrenal and thyroid glands release hormones and corticosteroids that result in physical growth and other physical changes. The timing and tempo of puberty: girls mature physically earlier than boys.
