Chap 4 Tissues

• Stratified squamous epithelium is a multi-layered epithelium that forms the outer layer of the skin and lines the mouth, throat, and vagina.
• Simple columnar epithelium consists of tall, cylindrical cells with a single nucleus and is found lining organs like the stomach and intestines.
• Pseudostratified columnar epithelium appears to be multilayered but all cells are attached to the basement membrane at their base.
• Bone cells can go through mitosis. Neurons and skeletal muscle cells do not typically undergo mitosis after they have matured.
• Functions of connective tissues is that they bind together and support, protect, store energy, transport
• Adipocytes are fat cells found in adipose tissue. They store fat
• Dense connective tissue has less interstitial fluid than loose connective tissue
• Epithelial tissue that functions in absorption and secretion are simple cuboidal and simple columnar epithelium
• First basic step in tissue repair is inflammation
• Basement membrane is a layer of glycoproteins that attaches epithelium to connective tissue
• Transitional epithelial tissue is a combination of differently shaped cells that can change their shape
• The function of Transitional epithelial is to allow for expansion of the organs.

  example: Found lining inside the ureters and in the bladder.
• when the cells change their shape from cuboidal to squamos the organ can expand
• Synovial membrane contains areolar connective tissue (few scattered cells on top)
• Stratified cuboidal tissues have many layers of epithelial cells that are cube shaped at the free surface
• Holocrine, merocrine and apocrine are examples of exocrine glands
• merocrine Gland is where only the secretion leaves the cell
• Holocrine gland is where the entire cell is secreted together with the excretory product.
• Cutaneous membrane contains stratified squamous epithelium and areolar connective tissue
• Adipocyte is scattered cell found in adipose tissue
• Simple columnar tissue has one layer of tall epithelial cells
• Mesenchyme is an embryonic connective tissue
• Reticular connective tissue is a type of connective tissue providing the framework for the spleen and lymph nodes
• Exocrine and Endocrine glands are comprised of epithelial tissue
• Proliferating (actively growing) blood vessels and connective tissue in tissue repair is granulation tissue
• Major type of tissue that is characterized by scattered cell in matrix is connective tissue
• Elastic cartilage tissue is found in the ear and epiglottis
• Serous membrane makes up the pleura
• Perichondrium is dense irregular connective tissue around cartilage that provides nutrients to the cartilage
• Mucus membrane contains an epithelium with goblet cells and lamina propria (areolar connective tissue)
• cardiac muscle tissues have branching cells
• Fibrocartilage tissue makes up most of the intervertebral disc
• The most common type of cartilage is hyaline cartilage
• Desmosome and gap junction is found in an intercalated disc
• Cells in nervous tissue that undergo mitosis are neuroglia
• Serous membrane contains simple squamous cells and areolar tissue
• Macrophage cell is a type of cell in connective tissue that “eats“ foreign material
• three types of fibers found in connective tissue are reticular, collagen and elastic
• Tendons connect muscles to bones and ligaments connect bone to bone
• Dense regular connective tissues make up tendons and ligaments
