Puberty marks the beginning of adolescence, and physical changes are noticeable during these years. During this stage, both genders experience a rapid rise in height as well as the development of sexual glands and adrenal glands, as well as hormonal changes. Boys exhibit the development of facial hair and a deeper voice. At the start of the menstrual cycle, girls experience breast and hip development. The physical changes that occur over these years are highly noticeable.
Besides, there are changes in the features of the brain. The amygdala is responsible for processing stress and related emotions, as well as influencing innate reactions and reflexes. The frontal brain, which is responsible for rational thinking, morals, judgements, and self-control, also grows. They begin to emerge at the start of adolescence and progress over time.
Young people experiencing the adolescence age are exposed to significant social, psychological, and behavioural changes. People discover their direction and develop abstract thinking and introspection. Students gain an understanding of values, talents, coping capacities, and the significance of a family and its values.
