Question

A girl's first menstruation is called:

A.) menarche.
B.) the menstrual cycle.
C.) puberty.
D.) ovulation.

Answer 1

Menarche is the term used to describe a girl's first menstruation, signifying the beginning of her ability to reproduce.

Step-by-step explanation:

A girl's first menstruation is called menarche. Menarche marks the onset of menstruation and is a significant event during female puberty. On average, menarche occurs at the age of 12.5 years in the United States, but there's a variation in age from as early as 8 to as late as 16 years, which can still be considered normal. This variation may be influenced by a mix of genetic and environmental factors, such as nutrition.

The menstrual cycle refers to the recurring changes in the female reproductive system, which includes the process of ovulation and menstruation. Menarche initiates the menstrual cycle, whereas ovulation is the part of the menstrual cycle where an egg is released from the ovary.

Menarche should not be confused with the entire menstrual cycle, ovulation, which is just one phase of the cycle, or puberty, which is the broader process of physical changes in which a child's body becomes an adult body capable of reproduction.
