    Shafts of hair are composed of:

    • A.

      Living dermal cells

    • B.

      Dead dermal cells

    • C.

      Living epidermal cells

    • D.

      Dead epidermal cells

    Correct Answer
    D. Dead epidermal cells
    Explanation
    Hair shafts are composed of dead epidermal cells. The hair shaft is the visible part of the hair that extends above the surface of the skin. It is formed by the hair follicle, which is located in the dermis layer of the skin. As the hair grows, the cells in the hair follicle push upwards and harden, eventually becoming keratinized and forming the hair shaft. These cells lose their nucleus and other organelles, making them dead cells. Therefore, the correct answer is dead epidermal cells.

    • D.

      Organelles, cells, tissues, organs, systems

    Correct Answer
    D. Organelles, cells, tissues, organs, systems
    Explanation
    The sequence " Organelles, cells, tissues, organs, systems" reflects the increasing complexity in the field of anatomy and physiology. Organelles, like the nucleus and mitochondria, operate within cells. Cells are the basic building blocks of life, which then combine to form tissues. These cells and their organelles come together to create organs, and multiple organs work in unison to form systems. This hierarchy demonstrates the progressive organization and complexity in understanding the human body's structure and function within the field of anatomy and physiology.
