1. Connective tissue Most abundant tissue by weight
Cells are farther apart than in epithelium
Predominant cells are fibroblasts
Much intercellular material (matrix)
Functions in binding structures together, filling spaces, providing support, protection, and production of blood cells

2. Loose connective Tissue (Areolar)
Binds skin to underlying organs
Fills spaces between muscles
Lies beneath epithelium to nourish those cells

4. Adipose tissue (Fat) Specialized loose connective tissue
Found beneath skin, between muscles, around organs, around joints
Acts as a protective cushion, insulator and storer of fat molecules

6. Fibrous (Dense) Connective Tissue
Dense, closely packed collagen and elastic fibers
Fewer cells
Strong
Poor blood supply
Slow to repair
Forms tendons & ligaments
Also found in the white of the eye & deeper dermis of the skin

8. Cartilage Matrix of collagen fibers
Cartilage cells (chondrocytes) found in chambers (lacunae)
Enclosed in a fibrous connective tissue covering (perichondrium)
Only blood supply is in the perichondrium

9. 3 types

10. A. Hyaline cartilage Most common
Found on ends of bones in joints, nose, rings of the trachea & bronchi

12. B. Elastic cartilage More flexible
Found in the external part of the ear & part of the larynx

14. C. Fibrocartilage Tough Shock absorber
Found between vertebral disks, between bones in knee & pelvic bones

16. Bone
Most rigid tissue due to collagen fibers and mineral salts in the matrix
Bone cells (osteocytes) found in chambers (lacunae)
Blood vessels found in canals throughout
Protects, supports, serves as an attachment for muscles, forms blood cells

18. Blood Matrix is plasma Red blood cells, white blood cells, & platelets
Transports nutrients, gases, wastes
