Types of Cells (Part 2)

Cells come in hundreds of varieties. Each type of cell in the body is uniquely designed for its function. Cells of the digestive system, for example, are greatly different in terms of their structure and function than cells of the nervous system.

This quiz will introduce you to the most common types of cells in the human body as well as their unique capabilities and functions.

  • Question of

    These type of cells are essential for light touch sensation and are found in the skin.

    • Merkel cells
    • Skeletal muscle cell
    • Neuron
    • Agranulocytes

    Correct Wrong

    Merkel cells, or tactile epithelial cells, are oval-shaped mechanoreceptors found in the skin that are responsible for light touch sensations. Highly sensitive skin, such as the fingertips, contains large numbers of them, which make synaptic contact with afferent nerve fibers in the body.

  • Question of

    A dense network of immune cells resides in the epidermis.

    • Langerhans cells
    • Ovum
    • Granulocytes
    • Agranulocytes

    Correct Wrong

    The Langerhans cells are dendritic cells of the skin. They are found in all layers of the epidermis, but are most prominent in the stratum spinosum. During skin infections, the local Langerhans cells take up microbial antigens and process them to become fully functioning antigen-presenting cells.

  • Question of

    Also known as the egg cell.

    • Ovum
    • Adipocyte
    • Osteocytes
    • Leukocytes

    Correct Wrong

    A female reproductive cell is an egg cell, or ovum (plural ova). A diploid cell (the zygote) is formed when egg and sperm fuse during fertilization.

  • Question of

    These cells line the body’s surfaces, such as the skin, blood vessels, urinary tract, and organs.

    • Epithelial cells
    • Myocytes
    • Melanocytes
    • Cardiomyocytes

    Correct Wrong

    Epithelial cells line the surfaces of your body. They can be found in your skin, blood vessels, urinary system, and organs.

  • Question of

    Cells that form the barrier between vessels and tissue and control the flow of substances and fluid into and out of a tissue.

    • Endothelial cells
    • Agranulocytes
    • Neuron
    • Platelet

    Correct Wrong

    In all blood vessels, endothelial cells form a single cell layer that regulates exchanges between the bloodstream and surrounding tissues. Vascular endothelium, which is directly in contact with blood, is known as vascular endothelium, while lymphatic endothelium is known as lymphatic endothelium.

  • Question of

    The muscle cells that make up the cardiac muscle.

    • Cardiomyocytes
    • Endothelial cells
    • Neuron
    • Langerhans cells

    Correct Wrong

    Cells that form the heart muscle are called cardiomyocytes. There are myofibrils in every myocardial cell, which are specialized organelles formed from long chains of sarcomeres, the fundamental units of muscle contraction.

  • Question of

    Also known as a muscle cell.

    • Myocytes
    • Merkel cells
    • Osteocytes
    • Erythrocytes

    Correct Wrong

    Myocytes are the smallest subunits of muscular tissues and organs throughout the body. The human body contains three types of muscle cells: skeletal, smooth, and cardiac.

  • Question of

    This muscle cells are found in the walls of hollow organs.

    • Smooth muscle cell
    • Neuroglia
    • Epithelial cells
    • Skeletal muscle cell

    Correct Wrong

    Smooth muscle cells are found in hollow organs, such as the stomach, intestines, urinary bladder, and uterus, and in passageways, including arteries and veins of the circulatory system, as well as respiratory, urogenital, and reproductive tracts.

  • Question of

    This muscle cell or fiber is a single cylindrical muscle cell.

    • Skeletal muscle cell
    • Cardiomyocytes
    • Platelet
    • Osteocytes

    Correct Wrong

    Skeletal muscle cells are one cylindrical muscle cell. Skeletal muscles are composed of hundreds or even thousands of muscle fibers bundled together and covered with connective tissue.

  • Question of

    Known as white blood cells, these cells are an integral part of the body’s immune system.

    • Leukocytes
    • Keratinocytes
    • Chondrocytes
    • Myocytes

    Correct Wrong

    Blood cells called leukocytes are made in the bone marrow and circulate in the blood and lymph. A leukocyte is an important component of an immune system. Through them, the body fights infections and other diseases.
