    Study Notes

    Cell Division

    • Cell division is a process that involves the division of a cell into two daughter cells.
    • There are two types of cell division: Mitosis and Meiosis.

    Mitosis

    • Mitosis is a type of cell division that produces two genetically identical daughter cells.
    • The DNA of the cell's nucleus is split into two equal sets of chromosomes.
    • Mitosis results in two daughter cells that are identical to the mother cell.

    Meiosis

    • Meiosis is a type of cell division that divides a diploid cell into haploid cells.
    • Meiosis involves the reduction of chromosomes by half.
    • The purpose of meiosis is the production of gametes, or sex cells.

    Gametogenesis

    • Gametogenesis is the process by which gametes are produced.
    • The process of gametogenesis involves meiosis.
    • There are two types of gametogenesis: Spermatogenesis and Oogenesis.

    Spermatogenesis

    • Spermatogenesis is the process by which sperm cells are produced.
    • The process of spermatogenesis involves the formation of spermatogonia, primary spermatocytes, secondary spermatocytes, and spermatids.
    • Spermatids undergo the 2nd meiotic division to form spermatozoa.

    Oogenesis

    • Oogenesis is the process by which egg cells are produced.
    • The process of oogenesis involves the formation of oogonia, primary oocytes, and secondary oocytes.
    • The corpus luteum plays a crucial role in the maintenance of the endometrium after ovulation.

    Corpus Luteum

    • The corpus luteum is a structure that forms from the Graafian follicle after ovulation.
    • The corpus luteum produces progesterone, which is necessary for the maintenance of the endometrium.
    • The corpus luteum must persist after ovulation to maintain the endometrium.

    Female Reproductive Organs

    • The female reproductive organs consist of the uterus, ovaries, and fallopian tubes.
    • The uterus is located in the anterior (front) of the pelvis, while the ovaries are located in the posterior (back) of the pelvis.
    • The fallopian tubes connect the ovaries to the uterus.

    Male Reproductive Organs

    • The male reproductive organs consist of the testes.
    • The testes are responsible for producing sperm cells.
    • The sperm cells are then transported through the male reproductive system.
