2. Dense
   1. Dense Regular

      Anotações:

      • strong collagen fibers that bind structures as parts of tendons and ligaments
   2. Dense irregular

      Anotações:

      • thicker, randomly distributed collagen fibers and is found in the dermis
   3. Elastic

      Anotações:

      • elastic fibers that make up hollow internal organs like the lungs and blood vessels
3. Specialized
   1. Cartilage

      Anotações:

      • provides support Consists of fibers and a gel-like substances Lacks a direct blood supply, so it is slow to heal Found at the ends of various bones; in the ear; in the larynx; and in the pads between the bones of the spinal column, pelvic girdle, and knees
   2. Bone

      Anotações:

      • matrix consists of mineral salts and collagen, heals rapidly, compact and spongy bone
   3. Blood

      Anotações:

      • Composed of cells suspended in fluid, produced in the tissue of hollow parts of certain bones
