• Which of the following refers to the dense connective tissue that binds the capsules that surround many organs?

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

  serous membrane
• Which of the following is not a characteristic of epithelial cells?

  They consist of a few cells but have a large amount of extracellular material
• Functions of connective tissue include all of the following except

  providing sensation
• What type of supporting tissue is found in the auricle of the ear and the tip of the nose?

  elastic cartilage
• An epithelium is connect to underlying connective tissue by

  a basement membrane
• Which of the following are wandering cells found in connective tissue proper?

  eosinophils, neutrophils, and mast cells
• Compare and contrast the role of a tissue in the body to that of a single cell

  A single cell is the unit of structure and function. Groups of cells work together as tissue
• Compare and contrast the functions of a tendon and a ligament

  A tendon is made of cords of dense regular connective tissue that attach a skeletal muscle to a bone. A ligament resembles a tendon but they usually connect bone to bone, more elastic fibers
• Compare and contrast exocrine and endocrine secretions

  Exocrine secretions occur in ducts that lead onto surfaces while endocrine secretions occur in the interstitial fluid and then enter into blood vessels
• Analyze the significance of the cilia on the respiratory epithelium

  Cilia at the surface of epithelium means mucous layer will be kept moving and the respiratory surface will be kept clean
• Compare a tendon to an aponeurosis

  Tendon is made of cords of sense regular connective tissue, aponeurosis is made of a sheet or ribbon of connective tissue that resembles a flat tendon
• A layer of glycoproteins and a network of fine protein filaments that perform limited functions together act as barrier that restricts the movement of proteins and other large molecules from the connective tissue to the epithelium. This illustrates...

  the reticular lamina
• Some connective tissue cells respond to an infection by dividing to produce daughter cells that differentiate into other types. This illustrates the behavior of...

  mesenchymal cells
• Analyze why pinching skin does not damage or distort underlying muscles

  Skin is separated from muscle by loose connective tissue. This provides padding, elastic, and movement
• Identify what stem cells are and analyze their functions

  Stem cells usually found in the deepest layers of epithelium, divide to replace cells at the epithelial surface
• Analysis of gradular secretion indicates that it contains some DNA, RNA, and membrane components such as phospholipids. What mode of secretion is this?

  Presence of DNA, RNA, membrane components suggests cells were destroyed during secretion
• Smoking destroys cilia found on many cells of respiratory epithelium, formulate a hypothesis with the knowledge

  Mucus produced by respiratory epithelium in response to irritation from smoking. Cilia beat upward, moving mucus to esophagus. No cilia prevents this leaving only coughing
