  1. ANATOMY – AS YOU ENTER • Pick up the Chapter 6 Worksheet and notes from table 1 • Today: Histology Review • Lecture: Intro to Integumentary System • Lab/Work period CALENDAR: MONDAY: PRACTICE QUIZ (+5 if turned in early) Tuesday: Quiz – Histology; Unit Work due

  2. Histology Review

  3. Term for study of tissue Histology Term for study of diseased tissues Pathology Tissue type that covers and lines, found on free surfaces, is avascular, and has rapid cell division Epithelial

  4. What is the name? Simple Squamous Epithelium • What is a location? Heart, Lungs, Kidneys, Blood vessels (diffusion areas)

  5. 3) What is the name? Simple cuboidal epithelium 4) What is a location? Glands

  6. Distinguish between an endocrine and exocrine gland • Endocrine – Makes hormones, are ductless – products released into bloodstream • Exocrine glands – Products exit through duct out of body (i.e. sweat gland) or into body cavity (i.e. salivary or gastric gland).

  7. 5) What is the name? Non-ciliated simple columnar 6) What is a location? Digestive, reproductive, urinary 7) What are the blue stained cells called? Goblet cells (mucous)

  8. 8) What is the name? Pseudostratified columnar 9) What is a location? Respiratory tract

  9. What tissue type contains goblet cells? • Columnar (Ciliated, non-ciliated, and pseudostratified) • What produces a “smoker’s cough”? • The cilia that move mucous are damaged by smoke. So the cilia don’t move when coughing occurs and the mucous remains trapped.

  10. 10) What is the name? Stratified squamous epithelium 11) What is a location? Skin (keratinized), mucous membranes

  11. Distinguish between the 3 epithelial membranes • Mucous membrane – Lines cavities that open to the exterior (dig, resp, repro, urinary) • Synovial – Lines joints (synovial fluid lubricates) • Serous – Lines cavities with no opening; Includes: • Pleura (lungs), Pericardium (heart), peritoneum (abdomen) • Parietal layer (outer) • Visceral layer (inner, over organ)

  12. 12) What is the name? Transitional 13) What is a location? Urinary bladder

  13. What is the most abundant tissue that supports, binds, transports, and stores energy • Connective • What are the 2 components of connective tissue • Cells and matrix • What are the 2 components of the matrix • Ground substance and fibers • What are the 3 fibers and characteristics of each • Collagen – strongest • Elastic – Stretching • Reticular – Framework and binding • What embryonic connective tissue gives rise to adult connective tissue? • Messenchyme

  14. 14) What is the name? Areola 15) What is a location? Subcutaneous (under skin)

  15. 16) What is the name? Adipose 17) What does it store? Fat (energy reserves)

  16. 18) What is the name? Hyaline (weakest, most abundant cartilage) 19) What is a location? Joints

  17. 20) What is the name? Fibrocartilage (strongest) 21) What is a location? (between vertebrae

  18. 22) What is the name? Elastic cartilage 23) What is a location? Ears, vocal cords

  19. 24) What is the name? Dense regular connective tissue 25) What is a location? Tendons and ligaments (avascular)

  20. 26) What is the name? Compact bone (strongest/support)

  21. Which heals more slowly – bone or tendon/ligament injuries? Why? • Sprains (damage to tendons/ligaments) usually take longer to heal because dense regular CT has poor blood supply compared to bone.

  22. 27) What is the name? Blood (for transport)

  23. What tissue type is specialized for contraction and movement? • Muscle

  24. 28) What is the name? Skeletal muscle (Striated and voluntary)

  25. 29)What is the name? Smooth muscle (non-striated, involuntary, lines organs)

  26. 30) What is the name? Cardiac muscle (in heart) Striated, involuntary, only in heart 31)What are the little lines between cells called? Intercalated disks

  27. 32) What is the name? Nervous tissue (sends and receives signals)

  28. What cell type sends/receives signals? • Neuron • What part of a neuron: a) receives signals b) sends signals? • A) dendrite b) axon • What are the supporting cells called? • Neuroglia
