Flashcards in Adolescent Medicine Deck (54):
1

Changes in physical growth

Average growth spurt 2-3 yrs, controlled by GH (insulin, thyroid, sex steroids also influence. 50% body weight and 25% height gained in spurt, 18-24 months earlier in females

2

Genitalia/Secondary sex characteristics

3-4 years of puberty,
Adrenarche (adrenal androgen synthesis)- 2 years before HPG
True puberty when gonaotropins increase

3

Physical changes in male puberty

Testicular enlargement @11-12 y/o
Facial/armpit hair 2 years after pubic hair begins

4

Female physical changes

Thelarche @ 9.5 years
Pubarche
menarche 2-3 years after thelarche, 12.5

5

Tanner stages (male)

1- preadolescent, no pubes
2-testes larger, downy hair
3-testes even bigger, penis longer, darker/coarse hair
4-darkening scrotal skin, big/wider penis, glans develops, hair over symph pubis
5-adult...hair to medial thigh

6

FSH

M- spermatogenesis
F-ovarian follicle development, ovarian granulosa cells make estrogen

7

LH

M- induces testicular Leydigs to make testosterone
F- stim ovarian theca cells make androgens, corpus luteum makes prog, midcycle surge in ovulation

8

Testosterone

Increase linear growth/muscle mass, penis/scrotum/prostate/seminalvesicles, hair growth, deepns voice, increases libido

9

Estradiol

M- increased rate epiphyseal fusion
F- stim breast develop, trig midcycle LH surge, stim lab/vag/uterine development, prolif endometrium, low level stim linear growth, high level => g-plate fusion

10

Progesterone

Converts endo to secretory endometrium

11

Adrenal androgens

M/F- stim pubic hair + linear growth

12

Tanner Females

1-preadolescent, no hair
2- elevation of breast/nipple projections, sparse downy hair on labia
3- enlarged breast, areola enlarges, dark/coarse/curly hair
4- areola/nipple project to form secondary mound, cover pubic symphysis
5- only nipple projects, hair to thigs

13

Early adolescence

10-13 years, Early shift to independence from parents, less interest in fam activities, mood/behavior changes, worried abt body changing, same-sex peer relationships, beginning of abstract thinking, lack of impulse control

14

Middle adolescence

Intense peer group involvement, romance starts
Increased abstract reasoning and risks

15

Late adolescence
