    Study Notes

    Reproductive System

    • The reproductive system has three main functions: production of gametes, fertilization, and development and nourishment of a new individual, as well as production of sex hormones.

    Formation of Gametes

    • Gametes are sex cells produced through meiosis, a type of cell division that occurs only in the testis and ovary.
    • Meiosis involves synapsis, where chromosomes align as pairs.
    • Crossing over occurs during meiosis, allowing exchange of genetic material between chromosomes.

    Male Reproductive System

    • The male reproductive system consists of the testes, a series of ducts, accessory glands, and supporting structures.
    • Ducts include the epididymides, ducta deferentia, and urethra.
    • Accessory glands include seminal vesicles, prostate glands, and bulbourethral glands.
    • Supporting structures include the scrotum and the penis.
    • Sperm cells are highly heat-sensitive and must develop at a temperature slightly lower than normal body temperature.
    • Meiosis in the male reproductive system involves two divisions: reduction division (1st meiotic division), where the number of chromosomes decreases from 46 to 23, and a 2nd meiotic division similar to mitosis.
