Study Notes
Sexual Reproduction
- Sexual reproduction involves meiotic divisions of germ cells producing haploid gametes (23 chromosomes) that fuse to form a diploid zygote (46 chromosomes).
- The zygote undergoes mitotic divisions to produce a large number of cells that differentiate to form various tissues of the new individual.
Stages of Mammalian Reproduction
- Gamete formation
- Fertilization
- Development of the embryo and fetus
The Reproductive System
- Becomes active after puberty
- Scrotum: a sac that holds the testes and maintains their proper temperature
The Urethra
- Divided into three sections: prostatic urethra, membranous urethra, and spongy urethra
Ovary and Oogenesis
- Ovary is the site of oogenesis and female sex hormone production
- FSH (follicle-stimulating hormone) stimulates oocyte maturation and release of an ovum
- One ovary releases an ovum each month, which is influenced by estrogen and progesterone hormones
- Ovarian cycle concerns the changes in the ovary during the menstrual cycle
