Skin And Body Membranes - Quiz

There are many different types of membranes located throughout the body. This particular test is to put what you know to the test.


Questions and Answers
  • 1. 

    Covering and lining membranes

    • A.

      Connective

    • B.

      Epithelial

    • C.

      Epidermis

    • D.

      Dermis

    • E.

      Parietal Layer

    Correct Answer
    C. Epidermis
    Explanation
    The epidermis is the outermost layer of the skin and acts as a protective barrier against external factors such as bacteria, UV radiation, and dehydration. It is made up of epithelial cells that are tightly packed together and lack blood vessels, making it avascular. The epidermis also contains specialized cells called melanocytes, which produce melanin, the pigment responsible for skin color. Overall, the epidermis plays a crucial role in maintaining the integrity and function of the skin.

    Surface simple squamous epithlium

    • A.

      Mucous Membranes

    • B.

      Cutaneous Membranes

    • C.

      Serous Membranes

    • D.

      Synovial Membrane

    Correct Answer
    C. Serous Membranes
    Explanation
    Serous membranes are the correct answer because they are composed of a simple squamous epithelium, which is a single layer of flat cells. Serous membranes line the body cavities and cover the organs within these cavities. They secrete a serous fluid that reduces friction between organs and allows them to move smoothly. Examples of serous membranes include the pleura, pericardium, and peritoneum.

    SKIN. Outermost protective boundry

    • A.

      Mucous Membranes

    • B.

      Serous Membranes

    • C.

      Synovial Membrane

    • D.

      Cutaneous Membrane

    Correct Answer
    D. Cutaneous Membrane
    Explanation
    The correct answer is Cutaneous Membrane. The cutaneous membrane refers to the skin, which is the outermost protective boundary of the body. It acts as a barrier against external factors such as pathogens, UV radiation, and physical trauma. The skin also helps regulate body temperature, excrete waste products through sweat, and contains sensory receptors for touch, pain, and temperature. Overall, the cutaneous membrane plays a vital role in protecting and maintaining the body's internal environment.

    Provide smooth surface, fibrous capsules that surround joints, contain no epithelial cells, and are composed of soft areolar connective tissue.

    • A.

      Serous Membrane

    • B.

      Cutaneous Membrane

    • C.

      Synovial Membrane

    • D.

      Mucous Membrane

    Correct Answer
    C. Synovial Membrane
    Explanation
    The synovial membrane is the correct answer because it meets all the given criteria. It provides a smooth surface and is composed of soft areolar connective tissue. It surrounds joints and does not contain epithelial cells.

    Rate this question:

  • 5. 

    Which of these is a connective tissue of a membrane?

    • A.

      Cutaneous

    • B.

      Serous

    • C.

      Synovial

    • D.

      Mucous

    Correct Answer
    C. Synovial
    Explanation
    Synovial is the correct answer because it is a type of connective tissue found in joints, providing cushioning and lubrication. This tissue helps reduce friction between bones during movement and allows for smooth joint function. Cutaneous refers to the skin, serous refers to the lining of body cavities, and mucous refers to the lining of various organs and passages. These tissues are not specifically connective tissues of a membrane.

    A tough protein within the skin that acts as a waterproofing agent.

    • A.

      Mucus

    • B.

      Melanin

    • C.

      Keratin

    • D.

      Carotene

    Correct Answer
    C. Keratin
    Explanation
    Keratin is a tough protein found in the skin that acts as a waterproofing agent. It forms a protective barrier on the skin's surface, preventing water loss and keeping the skin hydrated. Keratin is also responsible for the strength and elasticity of the skin, hair, and nails. It is produced by specialized cells called keratinocytes and is essential for maintaining the integrity and function of the skin.

    Serosa lining the abdomen and its organs

    • A.

      Pericardium

    • B.

      Pleura

    • C.

      Peritoneum

    • D.

      Synovial Membrane

    Correct Answer
    C. Peritoneum
    Explanation
    The peritoneum is the correct answer because it is the serous membrane that lines the abdominal cavity and covers the organs within it. It provides a protective and lubricating surface for the organs, allowing them to move and function properly. The peritoneum also helps to maintain the stability and position of the organs within the abdomen.

    Serosa surrounding the heart

    • A.

      Synovial Membrane

    • B.

      Pericardium

    • C.

      Peritoneum

    • D.

      Pleura

    Correct Answer
    B. Pericardium
    Explanation
    The pericardium is the correct answer because it is the membrane that surrounds the heart. It is a protective sac made up of two layers - the fibrous pericardium and the serous pericardium. The fibrous pericardium is the tough outer layer, while the serous pericardium is the inner layer that produces fluid to lubricate the heart and reduce friction during its movements. The pericardium helps to keep the heart in place and protects it from external damage.

    Lines a specific portion of the wall of the ventral body cavity

    • A.

      Visceral Layer

    • B.

      Parietal Layer

    Correct Answer
    B. Parietal Layer
    Explanation
    The parietal layer lines a specific portion of the wall of the ventral body cavity. In anatomy, the ventral body cavity refers to the space in the front of the body that contains various organs, such as the lungs, heart, and digestive organs. The parietal layer is the outer layer of a serous membrane that lines this cavity. It is attached to the body wall and helps to protect and support the organs within the cavity. The visceral layer, on the other hand, is the inner layer of the serous membrane that covers the organs themselves.

    Serosa surrounding the lungs

    • A.

      Peritoneum

    • B.

      Pericardium

    • C.

      Synovial Membrane

    • D.

      Pleura

    Correct Answer
    D. Pleura
    Explanation
    The pleura is a serous membrane that surrounds the lungs and lines the inside of the chest cavity. It consists of two layers, the visceral pleura which covers the lungs and the parietal pleura which lines the chest wall. The pleura helps to protect and cushion the lungs, as well as provide a smooth surface for them to move against during breathing. It also helps to create a pressure difference that allows the lungs to expand and contract properly.

    Sacs of connective tissue lined with synovial membranes Located near joints such as elbows, knees, shoulders

    • A.

      Tendon Sheaths

    • B.

      Bursae

    • C.

      Pleura

    • D.

      Pericardium

    Correct Answer
    B. Bursae
    Explanation
    Bursae are sacs of connective tissue lined with synovial membranes that are located near joints such as elbows, knees, and shoulders. These structures act as cushions and reduce friction between bones, tendons, and muscles during movement. Bursae contain synovial fluid, which lubricates the joints and allows for smooth and pain-free motion. Therefore, bursae are the correct answer in this case.

  • 12. 

    Folded parietal layers that covers the outside of the organs in that cavity

    • A.

      Visceral Layer

    • B.

      Parietal Layer

    Correct Answer
    A. Visceral Layer
    Explanation
    The correct answer is "Visceral Layer". The visceral layer refers to the folded parietal layers that cover the outside of the organs in a particular body cavity. This layer is responsible for protecting and supporting the organs within the cavity. It is called the visceral layer because it is closely associated with the organs themselves, as opposed to the parietal layer which lines the cavity walls.
