Q

Ovum (plural ova)

A

The ovum is the female sex cell, also called the egg; the male equivalent is sperm.

22
Q

Uterus

A

The uterus is a muscular enclosure at the top of the vagina that holds the fetus during pregnancy.

23
Q

Vagina

A

The vagina is the muscular tube in females leading from the labia at its opening to the uterus.

24
Q

Cervix

A

The cervix is the opening to the uterus.

25
Q

Hymen

A

The hymen is a fold of skin partially covering the opening to the vagina.

26
Q

Clitoris

A

The clitoris is the part of the external genitals in females that is the primary source of sexual stimulation.

27
Q

Glans

A

The glans is the part of the clitoris or penis that is most sensitive to stimulation.

28
Q

Shaft

A

The shaft is the part of the clitoris or penis that becomes erect during sexual stimulation.

29
Q

Prepuce

A

The prepuce is a thin skin covering the glans of the clitoris or penis.

30
Q

Testes

A

Testes are structures within the male reproductive system contained in the scrotum that produce sperm and male sex hormones.

31
Q

Sperm

A

Sperm is the male sex cell; the female equivalent is the ovum.

32
Q

Circumcision

A

Circumcision is the surgical removal of the prepuce covering the glans of the penis.

33
Q

Female Genital Mutilation

A

Female genital mutilation is the cutting out of the entire clitoris, the primary source of sexual stimulation in females, along with removing the inner labia and sewing shut most of the outer labia.

34
Q

Outer Labia

A

The outer labia are the outer folds of skin surrounding the opening of the vagina and the clitoris.

35
Q

Menarche

A

The menarche is the occurrence of a girl’s first menstrual period.

36
Q

Anovulatory

A

Anovulatory menstrual cycles are menstrual cycles that do not include the release of an egg.

37
Q

Leptin

A

Leptin is a hormone secreted by fat cells that may play a role in menarche.

38
Q

Spermarche

A

Spermarche is a boy’s first ejaculation of seminal fluid.

39
Q

Nocturnal Emmision

A

A nocturnal emission is a spontaneous ejaculation of seminal fluid during sleep; it is sometimes called a wet dream.

40
Q

Secular Trend

A

The secular trend is the earlier onset of puberty, faster growth, and larger size reached by adolescents today than in the past.

41
Q

Asynchrony

A

Asynchrony refers to the differences in the timing of pubertal changes within an adolescent or from one adolescent to the next.

42
Q

Early Maturation

A

Early maturation is pubertal maturation occurring earlier in adolescents than the norm for their sex.

43
Q

Late Maturation

A

Late maturation is pubertal maturation occurring later in adolescents than the norm for their sex.

44
Q

Self-Esteem

A

Self-esteem is the individual’s overall positive or negative evaluation of herself or himself.

45
Q

Maturational Deviance Hypothesis

A

The maturational deviance hypothesis is an explanation for the effects of asynchronous development that attributes the effects of timing to changing adolescents’ status relative to their peers.

46
Q

Stage Termination Hypothesis

A

The stage termination hypothesis is an explanation for the effects of early maturation as being because the adolescents did not have as much time as needed to complete the developmental tasks of middle childhood.

47
Q

Adult Status Hypotheseis

A

The adult status hypothesis is an explanation for the effects of asynchronous development that attributes the effects of timing to the status that awaits adolescents of either sex when they become adults.

48
Q

Body Image

A

Body image is individuals’ satisfaction or dissatisfaction with their image of their bodies.

49
Q

Overweight

A

Individuals are considered to be overweight when their weight is at or above the 95th percentile for their body mass index.

50
Q

Body Mass Index (BMI)

A

The body mass index is one’s weight in kilograms divided by the square of one’s height in meters; since body fatness varies with age and sex, percentiles for BMI are specific to age and gender.

51
Q

Poor Families

A

Poor families are families with incomes below the federal poverty level.

52
Q

Low-Income Families

A

Low-income families are families with incomes no greater than twice the federal poverty level.
