    Simple cuboidal epithelium is found  

    • Forming the kidney tubules.

    • Lining the trachea.

    • At the surface of the skin.

    • Lining the air sacs of the lungs

    • Lining blood vessels.

    Correct Answer
    A. Forming the kidney tubules.
    Explanation
    Simple cuboidal epithelium is a type of tissue that consists of a single layer of cube-shaped cells. It is specialized for secretion and absorption, and is found in areas where these functions are important. The kidney tubules are responsible for the reabsorption of water, ions, and other molecules from the filtrate, as well as the secretion of waste products. Therefore, it makes sense that simple cuboidal epithelium would be found in the kidney tubules, as it allows for efficient absorption and secretion processes.

    ________ support, protect, and nourish nerve cells

    • Barriers

    • Enzymes

    • Neurolgia

    • Secreations

    • Platelets

    Correct Answer
    A. Neurolgia
    Explanation
    Neuroglia is a type of cell in the nervous system that provides support, protection, and nourishment to nerve cells. It is responsible for maintaining the structural integrity of the nervous system and creating a suitable environment for nerve cell function. Neuroglia cells also play a role in repairing damaged nerve tissue and regulating the chemical balance within the nervous system.

    The reduction of friction between the parietal and visceral surfaces of an internal cavity is the function of  

    • Serous membranes

    • The lamina propria.

    • Synovial membranes.

    • Mucous membranes.

    • Cutaneous membranes.

    Correct Answer
    A. Serous membranes
    Explanation
    Serous membranes are responsible for reducing friction between the parietal and visceral surfaces of an internal cavity. These membranes produce a watery fluid that acts as a lubricant, allowing the organs to move smoothly against each other. The serous membranes line the walls of body cavities and cover the organs within them, such as the pleura in the thoracic cavity and the peritoneum in the abdominal cavity. This lubrication provided by serous membranes helps to prevent damage and allows for efficient movement and functioning of the organs.

    • Cells; cellular; interstitial fluid

    • Interstitial fluid; ducted; cells

    • Interstitial fluid; ductless; ducts

    • Ducts; ducted; interstitial fluid

    • Interstitial fluid; ducted; interstitial fluid

    Correct Answer
    A. Interstitial fluid; ductless; ducts
    Explanation
    Endocrine glands empty their products into interstitial fluid and are referred to as ductless glands, while exocrine gland secretions empty into ducts or onto surfaces.

    Examination of a tissue sample reveals groups of cells united by junctional complexes and interlocking membranes. The cells have one free surface and lack blood vessels. The tissue is most likely ________ tissue.  

    • Connective

    • Muscle

    • Epithelial

    • Neural

    • Adipose

    Correct Answer
    A. Epithelial
    Explanation
    The given description of the tissue sample suggests that it is composed of cells that are united by junctional complexes and interlocking membranes. These characteristics are typical of epithelial tissue, which forms the lining of body surfaces, cavities, and organs. Epithelial tissue also has one free surface and lacks blood vessels. Therefore, the tissue in question is most likely epithelial tissue.

    Rate this question:

  • 47. 

    The epithelium that lines the body cavities is known as

    • Adipose

    • Mesothelium

    • Epithelium.

    • Fat tissue.

    • Connective tissue

    Correct Answer
    A. Mesothelium
    Explanation
    The correct answer is mesothelium. Mesothelium is the epithelium that lines the body cavities. It is a simple squamous epithelium that provides a protective barrier and helps to reduce friction between organs and body cavities. Adipose tissue is a type of connective tissue that stores fat, but it does not line body cavities. Connective tissue is a broad category that includes various types of tissue, but it is not specific to lining body cavities.

  • 48. 

    Which type of connective tissue  is found between the ribs and the sternum, or supporting the trachea?  

    • Elastic

    • Dense regular

    • Areolar

    • Fibrous

    • Hyaline cartilage

    Correct Answer
    A. Hyaline cartilage
    Explanation
    Hyaline cartilage is the correct answer because it is the type of connective tissue that is found between the ribs and the sternum, as well as supporting the trachea. Hyaline cartilage is a smooth and flexible type of cartilage that provides support and reduces friction between bones. It is commonly found in areas where flexibility and support are needed, such as in the ribcage and trachea.

    DEAD SKIN CELLS ARE SHED IN THE SHEETS BECAUSE THEY ARE HELD TOGETHER BY SPOTS, SUCH STRONG INTERCELLUAR CONNECTIONS ARE CALLED

    • JUNCTIONAL COMPLEXES

    • INTERMEDIATE JUNCTIONS

    • GAP JUNCTIONS

    • DESMOSOMES

    • TIGHT JUNCTIONS

    Correct Answer
    A. DESMOSOMES
    Explanation
    Desmosomes are strong intercellular connections that hold cells together tightly. They are responsible for the adhesion of cells in tissues that experience mechanical stress, such as the skin. Dead skin cells are shed in the sheets because the desmosomes that hold them together break down, allowing the cells to be sloughed off.
