  1. Tissues
    groups of similar cells with common functions
  2. Types of Tissues
    • Epithelial
    • Connective
    • Muscle
    • Nerve
  3. Epithelial Tissue
    covering and lining
  4. Epithelial Examples
    • Skin Surface
    • Glands
    • GI
    • Cardiovascular
    • Respiratory
    • Urinary 
    • Reproductive
  5. Connective Tissue
    support and connections
  6. Connective Examples
    • Bone
    • Blood
    • Fat
  7. Muscle Tissues
    movement
  8. Muscle Examples
    • Skeletal
    • Cardiac
    • Smooth
  9. Nerve Tissue
    sends information by electrical and chemical signals
  10. Nerve Examples
    • Brain
    • Spinal Cord
    • Nerves
  11. Characteristics of Epithelial Tissue
    • Mostly Cells
    • Polarity
    • Basement Membrane
    • Avascular
    • Regeneration
    • Exposed for Free Surface
  12. Functions of Epithelial Tissue
    • Protection
    • Control Permeability
    • Sensations
  13. Ways to name Epithelial Tissues
    • Squamous
    • Cuboidal
    • Columnar
    • Simple
    • Stratified
  14. Types of Glands
    • Endocrine
    • Exocrine
  15. Endocrine Glands
    • Secretes to Blood
    • Often ductless
  16. Exocrine Glands
    • Secrete onto surface or duct
    • 1. Unicellular: goblet and mucous, GI and respiratory system, produce mucus
    • 2. Mulicellular: usually surrounded by connective tissue, classified by structure and secretion mode
  17. Connective Tissue Characteristics
    • Common origin (same part of embryo)
    • varying vascularity 
    • Extensive extracellular matrix
  18. Connective Tissue Matrix
    • Ground Substances-liquid and proteins
    • Protein Fibers-proteins
    • 1. Collagen: fibrous protein, cross-linked
    • 2.Elastic: long, thin, networks, stretch and recoil
    • 3. Reticular: network, hooked to collagen, example is basement membrane
  19. Connective Tissue Cells
    • Each class of CT has its own cell
    • Immature= blasts
    • Mature=cytes
    • White Blood Cells- immune
    • Mast Cells-local inflammation allergies 
    • Macrophages-scavengers
  20. Functions of Connective Tissues
    • Structure
    • Transport
    • Protect
    • Support, surround, and interconnect others
    • Store Energy
    • Defense
  21. Blood: CT
    • blood cells from hematopoietic stem cells
    • Matrix: fluid (plasma) + proteins
    • Transporter: function
  22. Cartilage Connective Tissue
    • Chondroblasts and cytes
    • collagen + significant ground substance 
    • good at compression, smooth (end of bones)
  23. Bone Connective Tissue
    • osteoblasts, cytes, and clasts (responsible for breakdown/recycling bones)
    • collagen + salts
    • remodeled, blood vascular
  24. Loose Connective Tissue
    • Areolar – fibroblasts + significant
    • Ground substance
    • Stores H2O and salts (edema is the swelling of lymph)
    • Widely distributed
    • Superficial fasciaà example (just deep to skin;  hypodermis is a type of superficial fascia

    • •Adipose – adipocytes, energy storage, insulation
    • •Vascular – lots of blood vessels

    •Reticular – fibroblasts 

    •Reticular fibers- greater %

    •Bone marrow, spleen
  25. Dense Connective Tissue
    • Regular:
    • 1.Fibroblasts
    • 2.One fiber direction (don’t stretch)
    • 3.Tendons, ligaments, deep fascia (around muscles; contain them)

    • Irregular: 
    • 1.Fibroblasts
    • 2.Network of fibers (all directions, cross each other; resists pulling in
    • multiple directions)
    • 3.Skins Dermis, joint capsules, organ covers
  26. Examples of Tissues:
    • Membranes:epithelia and connective tissues
    • 1.Cutaneous- skin/integumentary
    • 2.Mucous-lining digestive/respiratory
    • 3.Serous-line body cavities (ventral)
    • 4.Synovial- around joints, connective
    • tissue only

    • 2.Fascia:framework
    • a.Superficial –loose connective
    • tissue
    • b.Deep – dense connective tissue
    • c.Subserous – loose
