  1. Areolar Loose Connective Tissue
    Characteristics
    fibers are loosely arranged (not in bundles) and cells are intermingled loosely in matrix
  2. Areolar Loose Connective Tissue
    Function
    • packing agent
    • fills in space 
    • helps anchor BV and nerves to organs
  3. Areolar Loose Connective Tissue
    Location
    connective tissue component of serous membranes all over; no specific place
  4. Adipose
    Characteristics
    • prevalent cell: adipose cell
    • clusters of adipose cells bound tightly together and matrix is found between clusters
  5. Adipose
    Function
    • store fat for energy reserves 
    • insulator
    • shock absorber
    • helps protect organs from mechanical injury
  6. Adipose
    Location
    • hypodermis
    • bony eye sockets
    • kidney capsule made of adipose
  7. Dense regular connective tissue
    Characteristics
    • fibers (protein fibers) are densely packed in matrix, forming bundles
    • fibroblast squeezed between the bundles of fibers
    • regular because all fibers are in one direction
  8. Dense regular connective tissue
    Funciton
    • strength in the direction of stress
    • strength where tension is exerted
    • helps reduce pull (on muscles, for example)
  9. Dense regular connective tissue
    Location
    ligaments and tendons
  10. Dense irregular connective tissue
    Characteristics
    • tight bundles in all different directions
    • fibroblast squeezed between bundles of fibers
    • fibers (protein fibers) are densely packed in matrix forming bundles
  11. Dense irregular connective tissue
    Function
    • relieve stress in many different directions
    • provide strength in many different directions
  12. Dense irregular connective tissue
    Location
    dermis of skin
  13. Hyaline cartilage
    Characteristics
    • where prevalent fiber chondroblasts [cytes] 
    • prevalent fiber is collagenous, but you don't see it
  14. Hyaline cartilage
    Function
    • form 
    • protection
    • facilitates movement by reducing friction at movable joints
  15. Hyaline cartilage
    Location
    • found at articulating ends of bones that form a movable joint
    • cartilage of fetal skeleton
    • preformed cartilage model
    • rings of trachea to prevent collapse
  16. Bone
    Characteristics
    • cellular matrix
    • osteoblasts--> osteocytes
    • osteoclasts
    • calcification hardens it 
    • BV and canaliculi run through it; spongy and compact bone
    • after bone is laid down, hydroxy appetite occurs and it hardens
    • covered by periosteum
    • highly vascular
  17. Bone
    Location
    • skeleton
    • long bones of body 
    • (diaphysis= compact bone to take stress)
  18. Bone
    Function
    • form
    • lever in movement 
    • protection of internal organs
  19. Blood
    Function
    • transport of materials 
    • temperature regulation 
    • defense
  20. Blood
    Location
    • found in circulatory system
    • carreis cells of body's defense system
  21. Blood
    Characeristics
    • cells are three types: RBCs, WBCs, and platelets
    • matrix=m fluid called plasma (mostly water)
    • WBC= nucleus
    • RBC= no nucleus
