  • Slide 1
  • Connective Tissue
  • Slide 2
  • Types of Connective Tissue Osseous Tissue (Bone Tissue) Loose Connective Tissue Areolar Tissue Adipose Tissue Reticular Connective Tissue Dense Connective Tissue Cartilage Blood
  • Slide 3
  • Osseous Tissue Hard Calcified matrix containing many collagen fibers Osteocytes lie in lacunae Well vascularized
  • Slide 4
  • Location Found in bones
  • Slide 5
  • Function Bone supports and protects Provides levers for the muscles to act on Stores calcium, minerals, and fat Marrow inside bones- site for blood cell formation
  • Slide 6
  • Bone Tissue
  • Slide 7
  • Areolar Tissue Gel like matrix composed of all types of fibers Contains phagocytes, white blood cells
  • Slide 8
  • Location of Areolar Tissue Lamina propria is found under mucous membranes Internal organs
  • Slide 9
  • Functions of Areolar Tissue Wraps and cushions organs Phagocytes engulf bacteria Holds and conveys tissue fluid (water, salts, nutrients)
  • Slide 10
  • Areolar Tissue
  • Slide 11
  • Adipose Tissue Closely packed fat cells have nucleus pushed to the side by large fat droplet. Similar matrix to areolar tissue
  • Slide 12
  • Location of Adipose Tissue Under skin Around kidneys and eyeballs In bones Within abdomen In breasts
  • Slide 13
  • Function of Adipose Tissue Provides reserve food fuel Insulates against heat loss Supports and protects organs
  • Slide 14
  • 1.Cell membrane 2.Nucleus 3.Fat vacuole
  • Slide 15
  • Slide 16
  • Reticular Connective Tissue Network of reticular fibers in a typical loose ground substance; reticular cells predominate.
  • Slide 17
  • Location of Reticular Tissue Lymphoid organs (lymph nodes, bone marrow, and spleen)
  • Slide 18
  • Function of Reticular Tissue Fibers form a soft internal skeleton (stoma) that supports other cell types (specially blood cells)
  • Slide 19
  • Slide 20
  • Slide 21
  • Dense Connective Tissue Primarily collagen fibers A few elastic fibers Major cell type is the fibroblast
  • Slide 22
  • Location of Dense Connective Tissue Tendons Most Ligaments Aponeurosis
  • Slide 23
  • Function of Dense Connective Tissue Attaches muscles to bones or muscles Attaches bones to bones Withstands great tensile stress
  • Slide 24

  • Slide 26
  • Cartilage Hyaline cartilage abundant collagen fibers in rubbery matrix; blue-white appearance; most abundant Elastic cartilage yellowish appearance Fibrocartilage
  • Slide 27
  • Location of Hyaline Cartilage Forms most of the embryonic skeleton Covers the ends of long joints in joint cavities Forms coastal cartilage of the ribs Cartilage of nose, trachea, and larynx
  • Slide 28
  • Location of Elastic Cartilage External ear Disk between vertebrae of spinal column Location of Fibrocartilage
  • Slide 29
  • Function of Cartilage Tissue Supports and reinforces Has cushioning properties Resists compression
  • Slide 30
  • Hyaline Cartilage
  • Slide 31
  • Vascular Tissue (Blood) Blood cells surrounded by blood plasma Fibers in blood are not visible until clotting occurs
