1. Simple squamous epithelium
    • "chain like fence" single layer flat cells
    • Function: diffusion
    • Location: inner lining of circulatory system and small sacs of the lungs (aveoli)
  2. Simple cuboidal epithelum
    • single layer cube shaped cells.
    • Function: SECRETION and absorption.
    • Location: glands of the body (e.g. ovaries, salivary glands, pancreas).
  3. Simple Columnar Epithelium
    • Single layer column shaped cells. 
    • Function: secretion and ABSORPTION. Bringing molecules into cells.
    • Location: Digestive tract (stomach --->anal canal).
  4. Pseudostratified columnar epithelium
    • pseudo= false (fake)
    • structure: single layer of cells of varying heights.
    • Function: secretion (of mucus)
    • Location:Upper respiratory tract
  5. Epithelial Tissue
    • Cover the body surface.
    • As covering and lining tissue.
    • Always found as a surface tissue.
  6. Connective Tissue
    • Between organs and tissues.
    • Connect.
    • Few cells with lots of extracellular material.
    • 4 Types: Blood, bone, cartilage and general connective tissue.
  7. Muscle Tissue
    • Highly specialized to contract (shorten) and generate force.
    • Contract.
    • Skeletal muscles of the body and many body organs. 
    • Heart and other internal organs.
    • 3 types: skeletal, smooth, cardiac
  8. Nervous Tissue
    • transmission of electrical signals, which relay information from one part of the body to another.
    • Conduct.
    • Specialized for conduction of electrical signals.
    • Brain, spinal cord, and nerves.
  9. Epithelial Tissues
    Always Avascular
  10. Squamous (flat)
    "squashed" flat cells
  11. Cuboidal
    cube shaped cells
  12. Columnar
    Column shaped cells
  13. Simple
    one cell layer
  14. stratified
    multiple cell layers
  15. Stratified Epithelial Tissues
    • skin "brick wall"
    • Multiple layers of flat cells (squashed cells)
    • Functions: protection against abrasion
    • Location: outer layer of the skin, mouth -->esophagus
  16. Stratified columnar epithelium
    Structure: Multiple layers of column-shaped cell
  17. Transitional (stratified cuboidal) epithelium
    • Structure: "transitions" between being 6 <-->3 cell layers thick
    • Function: designed to stretch
    • Location: Urinary bladder
  18. connective tissues
    are vascular
  19. Soft Connective Tissues
    Blood, Bone, Cartilage, General connective tissues
  20. Connective Tissue
    • is made up of 2 basic building blocks: cells and ECM (extracellular matrix)
    • All connective tissues have a lower % of cells than ECM (less cells more ECM)
    • Many connective tissues have a rich nerve and blood supply.  (cartilage is an exception; its avascular and lacks nerves).
  21. Connective tissue
    • connective tissue proper
    • adipose tissue
    • reticular tissue
  22. Cartilage (skeletal support tissue)
    Firm to rubbery connective tissue
  23. Bone (skeletal support tissue)
    Hard connective tissue
  24. Blood(unique connective tissue)
    Fluid connective tissue
  25. Fixed cells
    stationary cells of CT proper
  26. Mesenchymal cell
    stem cells
  27. Fibroblast/fibrocyte
    Produce fibers either collagen or elastic fibers
  28. Adipose cells
    store lipid (energy reserves)
  29. Ground Substance (interfibrillar substance)
  30. Collagen fibers
    gives great tensile strength
  31. Elastic fibers (elastin)
    Elastic-able to readily stretch and recoil
  32. General Connective Tissues
    5 types: Loose connective tissue, dense irregular, dense regular, elastic, adipose
  33. Connective tissue proper
    collagenous connective tissue
  34. Loose connective tissue (areolar)
    • Structure: small amount of collagen (even less elastin)
    • Distribution: attaches epithelium, surrounds vessels, neurons, muscle fibers
    • Function: creates space for passage of vessels and nerves.
  35. Dense irregular connective tissue
    • most important. Everywhere in body.
    • structure: LOTS of collagen in many directions (packed within tissue)
    • Distribution: Dermis, sclera (outer layer of eye)
    • wrappings
    • Function: strength in ALL directions.
  36. Dense regular connective tissue
    • Structure: LOTS of collagen in one direction
    • Distribution: Tendons and ligaments
    • Function: Strength in ONE direction.
  37. Elastic Connective Tissues
    • Structure: LOTS of Elastin
    • Distribution: Found in skin, lungs, arteries, veins
    • Function: Can stretch and recoil
  38. Adipose Tissue
    • Structure: LOTS of adipose cells
    • Distribution: Beneath skin, around organs, in bone morrow.
    • Function: Energy storage, insulation, cushion and protect.
