  1. Muscle Tissue Contracts to Produce Movement

    ---Mucle :
    • Skeletal
    • moves body parts
    • Voluntary, multinucleated (long, Large)



  2. Muscle Tissue Contracts to Produce Movement
    Cardiac Muscle:
    • Smooth mucle
    • Invouluntary,signal nucleus
  3. Muscle Tissue Contracts to Produce Movement
    Smooth Musscle
    • Surrounds hallow structures
    • Invouluntary, single nucleus
  4. FYI: Skeletal Muscle (x100) Skeletal Muscle cells are very long and have many nuclei
  5. Fyi: Cardiac muscles (x225) Cardiac muscles cells interconnect with eachother.
  6. FYI: sheet of smooth muscle (X250) smooth muscle cells are thin and tapered
  7. Nurevous Tissues Transmit Impulses
    Neuron:
    Specialized nervous system cell
  8. Nurevous Tissues Transmit Impulses
    Neuron:FUNCTION
    Generate and transmit electrical ipulses
  9. Nurevous Tissues Transmit Impulses
    Neuron:STRUCTURAL COMPONENTS:
    cell body, dendritesiaxon
  10. Nurevous Tissues Transmit Impulses
    GLIAL CELLS:
    support nuerons
  11. Organ and organ systems perform complex functions
    ORGANS:
    Contain two or more tisssues types joined together;perform specific functions
  12. Organ and organ systems perform complex functions
    ORGANS SYSTEMS:
    groups of organs that perform a common function
  13. Organ and organ systems perform complex functions
    ORGANS: EXAMPLES:
    • digestive system: mouth, throat, stomach,intestines and liver
    • Lymphatic system:lymph nodes, tonsils, and spleen
  14. Body cavaties
    ANTERIOR CAVITY:
    • Thoracic cavity
    • twopleural cavities
    • Pericardial cavity
  15. Body Cavities
    ABDOMINAL CAVITY:
    • Prosterior cavity
    • Cranial cavity
    • spinal cavity
  16. BODY CAVITIES
    • Tissue membrane (serous membrane) lines body cavities
  17. Tissue Membrnes
    SERIOUS MEMBRANE
    • reduces friction between organs
    • Ex: Pleural membrane around lungs
  18. Tissue Membrnes
    Mucous membrane:
    • lubricates surface, captures debris
    • lines the body cavities open to the oustside
  19. Tissue Membrnes
    SYNOVIAL MEMBRANE:
    • Lines spaces in movable joints
    • secrete synovial fluid (knee)
  20. Tissue Membrnes
    CUTANEOUS MEMBRANE:
    skin
  21. FYI: LUNG PLUERA (SEROUS MEMBRANES)
  22. VISECUREAL PLURA
    layer of plura lining the surface of the lungs
  23. PARIETAL PLUEURA
    lines the thoratic body wall
  24. The skin as an Organ System
    The Proper Name is...
    Integumentary system
  25. The skin as an Organ System
    Includes:
    skin, hair, nail,gland
  26. The skin as an Organ System
    FUNCTIONS
    • prevent dehydration
    • protects from injury
    • serves as defence against microorganisms
    • regulates body temperatur
    • makes vitamin D
    • provides sensations
