Basic steps in Human Reproduction 1. Gametogenesis 2. Insemination 3. Fertilization 4. Blastocyst development 5. Implantation 6. Embryo development 7. Parturition
Male Reproductive Systerm The 1. Testes 2. Accessory ducts 3. Glands 4. External Genitalia male reproductive system has four main parts:
Female Reproductive System The human female reproductive system is specialised to support the process of gametogenesis, ovulation, fertilisation, pregnancy, birth and child care. The parts of the female reproductive system are: 1. A pair of ovaries 2. A pair of oviducts 3. Uterus 4. Cervix 5. Vagina 6. External genitalia 7. Mammary glands
Uterine fundus Uterine cavity Isthmus Ampulla Infundibulum Ovary Endometrium Myometrium Perimetrium Fimbriae Cervix Cervical canal Vagina
Ovaries . They are the primary female sex organs They produce the female gamete- ovum They also produce steroid hormones (Ovarian hormones) . 2-4cm in length and connected to the pelvic wall and uterus by ligaments . Each ovary is covered by a thin epithelium enclosing an ovarian stroma Ovarian stroma- It is the matrix of the ovary and is divided into two zones Peripheral cortex Inner medulla
Uterus . It is also called as the womb . It is shaped like an inverted pear It is attached to the pelvic wall by ligaments The uterus is the part where the embryo develops into the foetus The uterus opens into the vagina through a narrow cervix . Uterine wall has three layers of tissues: perimetrium, myometrium and the endometrium It is the thin external membranous layer Perimetrium: . Myometrium: It is the thick middle layer made up of smooth muscle. It exhibits strong contractions during the delivery of the baby . Endometrium: It is the inner glandular layer that lines the uterine cavity. It undergoes periodic changes during the menstrual cycle.
Cervix . It is a narrow canal connecting the uterus to the vagina Cervical canal: The cavity of the cervix is called as the cervical canal. . Birth canal: The cervical canal along with the vagina forms the birth canal
External female genitalia They consist of: mons pubis, labia majora, labia minora, hymen and clitoris Mons pubis: It is a mass of fatty tissue covered by skin and hair Labia majora: They are fleshy folds of tissue that extend from the mons pubis and cover the vaginal opening Labia minora: They are the paired folds of tissue under the labia majora Hymen: It is a membrane that partially covers the opening of the vagina. It is often torn during the first intercourse or coitus. It can also be broken by active participation in some sports like horseback ridin vaginal tampon, etc. In some women the hymen can persist even after coitus. The presence or absence of hymen is not a reliable indication of virginity or sexual experience g, cycling, etc., a sudden fall or jolt, insertion of a
Mamary glands The presence of functional mammary glands is characteristic of all female mammals . They are paired structures of breasts that contain glandular tissue and variable amounts of fats e Glandular tissue in each mammary gland consists of 15-20 mammary lobes. The mammary lobes have clusters of cells called alveoli The cells of alveoli secrete milk. The milk is stored in the lumen or cavities of the alveoli . The alveoli open into mammary tubules. The tubules of each lobe join to form a mammarv duct. . Several mammary ducts join to from a wider mammary ampulla . The mammary ampulla is connected to a lactiferous duct through which milk is sucked out.
