Study Notes
- All mammals reproduce sexually, with internal fertilization and development.
- Females have organs to make gametes, a place for fertilization, and a uterus for embryo development.
- Males have testes to make sperm, seminal vesicles and prostate gland to add fluid to semen, and a urethra to excrete sperm and urine.
- The menstrual cycle is a series of events in which the lining of the uterus is built up each month in preparation for the implantation of an embryo.
- Hormones secreted by the ovary include oestrogen and progesterone.
- FSH causes the development of the follicle and ovum, while LH brings about ovulation and development of the corpus luteum.
- The sperm has a head, middle piece, and long tail to allow it to swim and fertilize an ovum.
- The ovum has a jelly coat, corona radiata, and is moved along by contractions of the oviducts and cilia.
- Fertilization takes place close to where the ovum enters the oviduct, and the embryo moves towards the uterus for implantation.
- Implantation takes place approximately 7 days after fertilization.
