  1. What is histology
    The study of Tissues
  2. What are the four major tissue types?
    • Connective
    • Muscle
    • Neural
    • Epithelial
  3. Features of Epithelial Tissue
    • Covers exposed surfaces
    • Lines internal passageways
    • Produce glandular secretions
  4. Where is epithelial tissue found?
    • Skin
    • Glands
    • Line passageways
    • Line Cavities
  5. Types of Epithelial Tissue
    Squamous, Cuboidal, Columnar, Transitional, and stratified and stratified variants
  6. Simple Squamous Epithelial Tissue
    • Flat Shape allows substances to either diffuse easily through the cell or be filtered through it.
    • Secretions reduce friction
    • Lines body cavities, blood vessels, heart, alveoli of lungs
  7. Simple Cuboidal Cell
    • Function Secretion and absorption
    • Location: Ducts of glands; kidney tubules; follicles of thyroid gland
  8. Simple Columnar Epithelial
    • Ciliated: found in uterine tubes
    • Non ciliated: Stomach, small intestine large intestine, and gall bladder
    • function: absorption; secretion of mucus, enzymes, and other substances.
    • also move things with cilia
  9. Pseudostratified columnar epithelium
    • Ciliated: Nasal cavity, trachea, and bronchi
    • Non Ciliated: ducts of male reproductive tract
    • Function: protection; secretion; movement of mucus by cilia
  10. Stratified squamous epithelium
    • keratinized: epidermis of skin
    • non-keratinized: Lining of mouth, pharynx, esophagus, anus, and vagina
    • Function: provides physical protection to underlying tissues against abrasion and pathogens
  11. Transitional Epithelium
    • Location: lines uterus, urinary bladder, urethra, and renal pelvis
    • function: easily allows stretching and recoiling
  12. What types of glands are there?
    Exocrine: excrete into external surfaces or ducts that connect to the exterior

    Endocrine: secrete hormones or precursors into interstitial fluid (distribution into bloodstream)
  13. Features of connective tissue:
    • Specialized Cells
    • Extracellular Protein Fibers
    • Matrix (ground substance)
  14. Types of connective tissue
    • Connective Tissue Proper
    • Fluid Connective Tissue
    • Supporting Connective Tissue
  15. Connective Tissue propper
    • Loose: areolar, Adipose, and reticular
    • Dense: Dense regular, Dense irregular, and elastic
  16. Fluid Connective Tissue
    • Blood: flows within cardiovascular system
    • Lymph: flows within lymphatic system
  17. four types of membranes
    • Mucous Membranes: Line passages and chambers that lead to the outside
    • Serous Membranes: line the pleura of the lungs
    • Cutaneous Membrane: covers the surface of the body
    • Synovial Membrane: covers mobile joint cavities, not opposing joint surfaces
  18. Faschia
    Connective tissue layers and wrappings that support and surround organs
  19. What tissues are epidermis made of
    stratified squamous, keratinized
  20. 5 layers of epidermis
    • Stratum Corneum
    • Stratum Lucidum
    • Stratum Granulosum
    • Stratum Spinosum
    • Stratum Basale
  21. What is the dermis made of?
    papillary layer of areolar tissue and a reticular layer of dense irregular connective tissue
  22. 2 layers of the dermis
    • papillary layer
    • Reticular layer
  23. Subcutaneous
  24. three things that affect skin color
    • genetics
    • sun exposure
    • blood stream
  25. Tactile corpuscle (meissner)
    fine touch
  26. Lamellated Corpuscle (Pacinian)
    Deep pressure and vibration
  27. Sudoriferous glands
    Sweat Glands
