  1. General Characteristics of Connective Tissue
    1) Connective tissues __, __, __, __, __, __, __, __, and __.
    2) What is the difference between epithelial tissue and connective tissue?
    • bind, support, protect, serve as frameworks, fill spaces, store fat, produce blood cells, protect against infection, and repair tissue damage
    • Connective tissues have abundant matrix, or intercellular material, throughout, and have good blood supplies (except cartilage)
  2. Major Cell Types of Connective Tissue
    1) the __ is the most common cell type and is a large, star shaped cell that secretes __ and is fixed in position
    2) Wandering __ function as scavenger cells and defend against infection.
    3) __ are large and are located near blood vessels where they release __ and _.
    • 1) fibroblast/ fibers
    • 2) macrophages
    • 30 mast cells/ heparin (anticoagulant)/ histamine (promotes inflammation)
  3. Connective tissue fibers:
    a) Strong __, made of the protein __, add strength for holding body parts together.
    b) __, made of the protein __, are stretchy and add flexibility to certain types of connective tissues.
    c) __ are thin __ fibers that form supportive networks in a variety of tissues
    • a) collagenous fibers (white fibers)/ collagen
    • b) elastic fibers (yellow fibers)/ elastin
    • c) reticular fibers/ collagenous

    1) This type of tissue forms __, __ membranes throughout the body that do what?
    2) __ are separated by a gel-like ground substance that contains __ and __ fibers.
    3) What does it do?
    • 1) delicate/ thin/ bind body parts together
    • 2) Fibroblasts/ collagenous/ elastic
    • 3) It binds the skin to underlying organs and fills spaces within muscles
  5. Adipose Tissue
    1) __ is connective tissue designed to __
    2) Where is it found?

    1) This tissue consists of densely packed __ and is very __ but lacks a __
    2) It is found as part of __ and __.
    • 1) collagenous fibers/ strong/ good blood supply
    • 20 tendons/ ligaments
  7. Cartilage
    1) Cartilage is a __ that provides a __ for various structures
    2) Cartilage cells (__) lie withink __ in the gel-like fluid matrix.
    3) __ is white with abundant fine __ fibers, is found __ and __.
    4) __, with elastic fibers, provides a __ for the __ and __
    5) __, with many __ fibers, is a tough tissue that provides a __ in __ and in __ and __.
    • 1) rigid connective tissue/ supportive framework
    • 2) chondrocytes/ lacunae
    • 3) Hyaline cartilage/ collagen/ at the ends of bones/ supports respiratory passages
    • 4) Elastic cartilage/ framework/ external ears/ parts of the larynx
    • 5) Fibrocartilage/ collagenous/ shock-absorbing function/ intervertebral disks/ the knees/ pelvic girdle
  8. Bone
    1) Bone is the most __, with deposits of __ and __ within the matrix.
    2) Bone cells, called __, lie within __ and are arranged in __ (__) around __
    3) Bone has a __, enabling __ after an injury.
    • 1) rigid connective tissue/ mineral salts/ collagen
    • 2) osteocytes/ lacunae/ concentric circles (osteons)/ osteonic canals
    • 3) good blood supply/ rapid recovery
  9. Blood
    1) Blood is composed of __ suspended in a __.
    2) It is formed in the __ inside __ and functions to __ throughout the body
