Study Notes
Reproductive System Overview
The reproductive system is a complex system that enables the production of offspring. It is essential for the survival of species.
Male Reproductive System
-
Primary Organs:
- Testes: produce sperm cells (spermatogenesis)
- Epididymis: stores and matures sperm
- Vas deferens: muscular tube that transports sperm
- Urethra: common passage for sperm and urine
- Penis: external male genital organ
-
Accessory Glands:
- Prostate gland: produces fluids that make up semen
- Seminal vesicles: produce nutrients for sperm
- Cowper's glands: produce lubricating fluids
Female Reproductive System
-
Primary Organs:
- Ovaries: produce egg cells (oogenesis)
- Fallopian tubes: transport eggs from ovaries to uterus
- Uterus: muscular organ that supports fetal development
- Cervix: lower part of uterus that opens into vagina
- Vagina: muscular canal that connects cervix to outside
-
Accessory Glands:
- Mammary glands: produce milk for lactation
Gametogenesis
-
Spermatogenesis:
- Process of sperm production in testes
- Involves meiosis and differentiation of sperm cells
-
Oogenesis:
- Process of egg production in ovaries
- Involves meiosis and differentiation of egg cells
Hormonal Regulation
-
Hormones involved:
- Testosterone (male): regulates sperm production and sexual characteristics
- Estrogen and progesterone (female): regulate egg production and menstrual cycle
-
Hypothalamic-pituitary-gonadal axis:
- Feedback loop that regulates hormone production and reproductive function
Learn about the male and female reproductive systems, including primary organs, accessory glands, gametogenesis, and hormonal regulation. Understand the processes of sperm and egg production, and how hormones regulate reproductive function.
