Study Notes
Biological Transitions
- Puberty: A period of physical changes leading to sexual reproduction.
- Endocrine System: Produces, circulates, and regulates hormones. Hormones are secreted by glands and travel through the bloodstream.
- Puberty Triggers: Genes and environmental factors (e.g., nutrition, light exposure) influence the timing and tempo of puberty.
- Somatic Development: Accelerated growth in height and weight, development of primary and secondary sex characteristics.
- Growth Spurt: Dramatic increase in height and weight during puberty. Peak rate varies by gender.
- Hormonal Feedback Loop: The hypothalamic-pituitary-gonadal (HPG) axis controls hormone levels.
- Adrenarche: Maturation of adrenal glands. Important in early sexual feelings, body odor, and stress response.
- Kisspeptin: A brain chemical that triggers the onset of puberty.
- Leptin: A hormone produced by fat cells that influences kisspeptin levels and thus, puberty.
- Melatonin: A hormone related to sleep patterns that can affect puberty onset.
- Hormonal Influences: Prenatal hormones organize brain structure, affecting behavior later. Puberty-related hormones alter behavior.
- Timing and Tempo: Variation in onset and maturation rate. Environmental factors (nutrition exposure, family relationships) influence the onset and tempo of puberty.
- Early vs Late Maturation: Early maturing boys are more popular, but also report more behavioral problems. Early maturing girls may have lower self esteem. Late maturing boys have better self-esteem.
- Eating Disorders: Obesity, Anorexia Nervosa, bulimia, and binge eating disorder (trends in disordered eating). Increased body dissatisfaction and dieting during puberty.
