Quiz: Cells, Tissues, & Membranes

  1. A human life begins as a single, newly fertilized cell.
  2. One average-sized adult body may consist of 100 million cells.
  3. Intricate arrangements of fine fibers and thousands of organelles exist within the cell nucleus.
  4. The nucleus determines how the cell will function, as well as the basic structure of that cell.
  5. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
  6. Epithelial tissue consists of tightly packed cells with little intercellular matrix, having one free surface.
  7. Connective tissue cells are able to reproduce twice as rapidly as epithelial cells.
  8. The cells in muscle tissue that generate and conduct impulses are called neurons.
  9. Mucous membranes line the body cavities that open to the outside.
  10. Synovial fluid lubricates the membrane and reduces friction and abrasion when organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall.
