Tissue Types + Identifying Histological Samples

Cards in this deck (55)

  1. 1What is the purpose of epithelial tissues?- forms barriers
    - lines organs/body cavities
    - INVAGINATIONS FORM GLANDS!!!
  2. 2What are the 4 basic characteristics of epithelial tissue?- AVASCULAR
    - POLARIZED (apical and basolateral surfaces differ)
    - little ECM
    -rests on basal lamina
  3. 3Identify the tissue type:Keratinized stratified squamous epitheliumIdentify the tissue type:
  4. 4Identify the tissue type:Pseudostratified EpitheliumIdentify the tissue type:
  5. 5Identify the tissue type:Pseudostratified EpitheliumIdentify the tissue type:

  12. 12Identify the tissue type:Transitional EpitheliumIdentify the tissue type:
  13. 13Where are transitional epithelium cells found?In the bladder --> confers flexibility
  14. 14Where are pseudostratified epithelium cells found? What functions are they associated with?Respiratory system and MALE reproductive tract
    - commonly associated with CILIA; mucus secretion
  15. 15Where are stratified squamous epithelium cells found? What functions are they associated with?- outer layer of skin, lines rectum, outer anus, oral cavity, esophagus, vagina
    - keratinized in skin
    PROTECTION
  16. 16Where are stratified cuboidal epithelium cells found? What functions are they associated with?exocrine glands, sweat and MAMMARY gland (relatively RARE!)
    PROTECTION AND SECRETION
  17. 17Where are stratified COLUMNAR epithelium cells found? What functions are they associated with?- excretory ducts, pharynx, urethra, anus (inner)
    PROTECTION
    (Columnar shape gives more room for specialized organelles****)
  18. 18Where are simple squamous epithelium cells found? What functions are they associated with?- vasculature, body cavities
    MUCUS SECRETION, VESSEL PERMEABILITY,
  19. 19Where are simple cuboidal epithelium cells found? What functions are they associated with?glands and ducts (esp. kidneys**)
    SECRETION AND ABSORPTION
  20. 20Where are simple COLUMNAR epithelium cells found? What functions are they associated with?digestive tract (VILI), fallopian tubes, excretory ducts
    PROTECTION, SECRETE MUCUS AND ENZYMES, ABSORPTIVE CELLS
  21. 21Glands are formed by ______Invagination of epithelial tissue
  22. 22The two types of glands are ____ and _____. _______ has ducts while ______ does not.- endocrine; exocrine
    exocrine (HAS DUCTS --> to release to surface)
    Endocrine (no ducts; secrete hormones in the blood)
  23. 23What is the purpose of CONNECTIVE tissues?- links together tissues and organs
    - structural and metabolic support
    - stores E
    - forms immune system
  24. 24Naming of connective tissue types is based on _____, _____ type and ______ type- density
    - fibre
    - cell
  25. 25There are 3 important cells in connective tissue what are they?1. fibroblast (wound repair)
    2. macrophages (immunity)
    3. Adipocytes (fat storage)
  26. 26What is ground substance and where is it secreted from?Ground substance = hydrated gel
    - secreted from FIBROBLASTS
  27. 27What are the 3 types of fibres found in connective tissue?- collagen (tensile)
    - elastic fibres (compression)
    - reticular fibres (scaffold)
  28. 28What is LOOSE connective tissue? What are theh 3 types?Loose: ECM>>>fibres (packing material between organs)
    1. Areolar (links organs and tissues; most common)
    2. Adipose
    3. Reticular (usually associated with lymphatic system)
