    Study Notes

    Mesodermal Derivatives During Embryonic Period

    • The kidneys, urinary bladder, ureters, and ducts are mesodermal derivatives during the embryonic period.
    • The primary function of mesodermal derivatives during the embryonic period is to form the muscles, skeleton, circulatory system, and excretory system.

    Blood Cell Formation

    • The bone marrow, derived from mesoderm, is crucial for blood cell formation during embryonic development.

    Skeletal Muscles and Connective Tissues

    • The paraxial mesoderm is a mesodermal derivative that gives rise to the skeletal muscles and connective tissues of the body.

    Urogenital System

    • The intermediate mesoderm is the mesodermal derivative that forms the urogenital system, including the kidneys, gonads, and ducts.

    Axial Skeleton and Associated Connective Tissues

    • The sclerotome, derived from mesoderm, is responsible for the formation of the axial skeleton and associated connective tissues.
