  1. Types of connective Tissue

  2. Connective Tissue Types Boneosseous 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 body • Bone is living tissue Figure 3.19a

  3. 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. 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

  5. Loose Connective Tissue There are 3 types of LOOSE Connective Tissue. Areolar connective Adipose Tissue Reticular connective tissue

  6. 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. 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 Figure 3.19f

  8. 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. 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
