Study Notes

Reproductive System Overview

Puberty marks the development of the reproductive system, starting around 10-11 years in females and 11-12 years in males.
Complete puberty occurs by 15-17 years for females and 16-17 years for males.
Menstruation involves the discharge of blood and tissues from the uterus, marking the end of the female reproductive cycle.

Key Terms

Endometrium: Innermost uterine layer; sloughed off during menstruation, comprising the stratum functionalis.
Ovulation: Release of an ovum from an ovary following the rupture of the ovarian follicle.
Menopause: End of a woman's reproductive capabilities.
Menarche: Onset of menstruation for females.
Gametes: Mature reproductive cells; include spermatozoa (mature male) and ovum (mature female).
Spermatogenesis: Development of sperm in the testes.
Oogenesis: Development of egg cells.

Female Reproductive Anatomy

Fimbriae: Finger-like projections that guide the egg from the ovary.
Uterus: Pear-shaped organ (7 cm long, 2 cm wide in non-pregnant state); also called the "hotel of baby."
Cervix: Strong muscular base of the uterus; facilitates the passage of sperm and menstrual flow.
Vagina: Smooth muscle organ; forms the birth canal and accommodates the penis during intercourse.

External Female Genitalia

Labia Majora: Outer folds of skin, containing sebaceous glands; encase other internal organs.
Labia Minora: Inner flaps that protect the vagina and urethra; meet to form the clitoral hood.
Clitoris: Highly sensitive erectile tissue involved in sexual pleasure.
Bartholin’s Glands: Secrete fluid for lubrication during intercourse.
Perineum: Diamond-shaped area surrounding the vaginal opening.

Phases of the Menstrual Cycle

Menstrual Phase: Days 1-5; involves sloughing of the endometrial lining, secretions, and blood.
Proliferative Phase: Days 3-14; epithelial cells multiply, and estrogen is secreted by growing follicles.
Ovulation: Occurs around mid-cycle; release of the ovum.
Secretory Phase: Days 15-28; endometrial lining thickens, preparing for potential implantation of a fertilized ovum.

Hormonal Regulation

Follicle Stimulating Hormone (FSH): Triggers follicular growth and estrogen secretion.
Luteinizing Hormone (LH): Promotes the development of ovarian follicles and estrogen secretion.
Gonadotropin-Releasing Hormone (GnRH): Stimulates the release of FSH and LH.
Estrogen: Influences secondary sexual characteristics and regulates the menstrual cycle.

Types of Twins

Identical Twins (Monozygotic): Develop from a single fertilized egg that splits, sharing the same genetic material.
Fraternal Twins (Dizygotic): Result from the fertilization of two separate eggs by two sperms, leading to genetically different siblings.
Triplets: Can occur through fertilization of one egg that divides into three, or splitting of two zygotes.

Embryology Terms

Follicle: Sac-like structure containing an immature egg.
Morula: Solid mass resulting from cleavage during early embryonic development.
