2 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Connective Tissue Types Bone osseous tissue  Composed of:  Bone cells (Osteocyte) in lacunae (cavities)  Hard matrix of calcium salts  Large numbers of collagen fibers Used to protect and support the bod y  Bone is living tissue Figure 3.19a

3 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Cartilage Tissue (3 types)  Hyaline (Articular -glassy) Cartilage: covers and protects bones; collagen fibers in a blue-white glossy material – Most Common (entire fetus structure)  Elastic Cartilage: Flexible cartilage (ear & Epiglottis)  Fibrocartilage: compressible; found in the spinal column between vertebrae & meniscus

4 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Dense Connective Tissue aka: Dense Fibrous Tissue  Collagen fibers with fibroblasts (fiber forming cells). Found in:  Tendons: Attach skeletal muscle to Bone  Ligaments: Connect bone to bone at joints  Dermis: the lower layers in the skin Dermis is like your HIDE

6 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Connective Tissue Types Areolar connective tissue  Most widely distributed connective tissue – Surrounds ORGANS  Soft, pliable tissue  Contains all fiber types  Can soak up excess fluid Figure 3.19e

7 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Figure 3.19f Connective Tissue Types Adipose tissue  Oil droplets take most of the cell’s volume (the nucleus is pushed to the side)  Forms the subcutaneous tissue found under the skin (Hypodermis), on some organs (kidney, eye) & stored in deposits (hips, breasts) Functions  Insulates the body  Protects some organs  Serves as a site of fuel storage

8 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Connective Tissue Types Reticular connective tissue  Delicate network of interwoven fibers  Forms stroma (internal supporting network) of lymphoid organs  Lymph nodes  Spleen  Bone marrow Figure 3.19g

9 Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings Connective Tissue Types Blood  Blood cells surrounded by fluid matrix  Fibers are visible during clotting  Functions as the transport vehicle for materials Figure 3.19h
