LAB EXAM 1

• Connective tissue

  Bind structures, support, protection, fill spaces, store fat, produce red blood cells
• Epithelial tissue

  Protection, filtration, secretion, and absorption
• Areolar tissue (connective)

  Binds skin, and fill spaces between organs.

  Light, pink color with collagen fiber, elastic fiber, fibroblast, and ground substance. (Light pink with darker spots and some white ground substance)
• Adipose tissue

  Functions as heat insulator beneath

  skin.

  provides stored energy supply in fat, droplets in cytoplasm.

  cell membrane nucleus, fat, droplet, blood vessel, and adipocyte. (mostly white background with light purple outline circle blobs)
• Reticular connective tissue

  Form supporting tissue in walls of liver and spleen.

  White blood cell, reticular fibers, fibroblast (white background with black defined squiggles)
• Dense regular connective tissue

  Main tissue of tendons and ligaments.

  Collagen fibers and fibroblast ~~~ wave motion
• Elastic connective tissue

  Occurs in some ligament attachments between vertebrae and larger artery walls.

  Collagen fiber, fibroblast, and elastic fiber. (Coal color and texture with some white spots)
• Hyaline cartilage

  Forms the ends of many long bones.

  Nucleus, chondrocyte, extracellular matrix. (Pink and purple multiple dot clusters with white centers)
• Elastic cartilage

  Forms framework of outer ear.

  Chondrocytes, elastic fibers and ground substance. (Purple colors with dragon skin and eye looking dots)
• Fibrocartilage

  Pads between vertebrae that are shock.

  Collagen, fibers, chondrocytes and extra cellular matrix. (Darker pink smooth clumped circle groups with white gaps)
• Compact bone

  Cells and solid matrix arranged around central canal.

  Matrick contains collagen, fibers and mineral salts.

  Central canal, osteon, and lacuna. (black and white tree trunk circles)
• Blood

  contains large amounts of fluid and transports, nutrients, wastes, and gases.

  Red blood cells, white blood cells, location of extracellular matrix a.k.a. plasma, and platelets

  (white background with red dots and a few purple—wbc)
• Simple squamous

  Single layer, flattened cells.

  Filtration, diffusion, osmosis covers surface.

  Air sacs of lungs, walls of capillaries.
• Simple cuboidal

  Single layer, cube shaped cells.

  Protection, secretion, and absorption.

  Lines kidney tubules and ducts of salivary glands.
• Simple columnar

  Single layer, elongated cells.

  Protection, secretion, and absorption.

  Linings of uterus, stomach, and intestines.
• Pseudostratified columnar

  Single layer, elongated, appears multiple layers but only one.

  Commonly possesses cilia, that move dust and mucus out of the respiratory airways. Protection, secretion, movement of mucus and substances.
• Stratified squamous

  Many layers, top cells flattened.

  Protection.

  Superficial layer of skin forms lining of oral cavity, esophagus, anal canal, and vagina.
