- 1. Connective Tissue Cells Matrix LocationFunction Ground Substance Fibers PROPER DENSE Regular or Collagenous (Fibrous) Fibroblasts- makes ground substance Fibrocytes- absorbs ground substance Gel-like Mostly collagen Tendons and ligaments Attaches muscle to bone or other muscle, withstands stress in one plane Irregular Gel-like Mostly collagen Dermis, around organs Withstands stress in all 3 planes Elastic very few open spaces Mostly elastic walls of large arteries, trachea and bronchi Allows recoil of tissue following stretching maintains pulsatile strength LOOSE Areolar Fibroblasts- makes ground substance Fibrocytes- absorbs ground substance Immune cells Adipocyte Gel-like Elastic, Reticular, Collagen Dermis, around organs Stretch and shock absorption Reticular Mostly reticular Spleen, organs, and lymph nodes, liver, kidney, bone marrow Makes cell supporting frame. Adipose Adipocytes Gel like but sparse Similar to areolar, but very sparse Under skin (hypodermis), around kidneys and eyeballs Provides reserve food fuel, insulates against heat loss, and supports and protects organs
- 2. CARTILAGE Hyaline Chondroblasts Chondrocytes glossy Collagen fibers ends of long bones,ribs, nose, trachea, and larynx Supports & reinforces, has cushioning properties, and resists compressive stress Elastic Mainly elastic fibers ear and epiglottis Maintains the shape of a structure while allowing great flexibility Fibrocartilage Thick collagen fibers Intervertebral discs, pubic symphysis, and discs of knee joints Tensile strength with the ability to absorb compressive stress BONE Bone Osteoblasts- produce the organic part of the matrix Osteocytes- mature bone cells Osteoclasts- help maintain the bone Gel-like ground substances that are calcified with inorganic salts Collagen bones that make up the skeletal system Support, leverage & movement, protection, calcium phosphate storage, and hematopoiesis BLOOD Blood Red blood cells – Erythrocytes White blood cells – Leukocytes Platelets – Thrombocytes Add up to 45% Fluid matrix called Plasma 55% absent Cardiovascular system Transporting nutrients, waste, gases, minerals, lipids, proteins, hormones. Maintain body temperature Control blood and body’s pH Balance of electrolytes. Immune response Clotting
