Types of Connective Tissue – Flashcards

Location: Dermis of skin (papillary region). Around some organs. (WebSite) Function: Support and strength. Holds a lot of matrix. Terms: Fibroblasts, macrophage, elastic fibers, collagen fiber bundles.

Location: Subcutaneous layer under skin (hypodermis). Function: Storage of energy and fat. Terms: Adipocytes, nucleus, lipid droplet.

Location: Spleen, lymphatic organs. Function: Support and strength. Framework of spleen and lymphatic organs and red bone marrow. Note: Reticular tissue forms the stroma or supporting framework for lymphatic organs and hemopoietic tissue like red bone marrow. Terms: Reticular fibers, reticulocytes.

Location: Spleen, lymphatic organs. Function: Support and strength. Framework of spleen and lymphatic organs and red bone marrow. Note: Reticular tissue forms the stroma or supporting framework for lymphatic organs and hemopoietic tissue like red bone marrow. Terms: Reticular fibers, reticulocytes.

Location: Tendon and ligament. Function: Give strength on same direction. Note: Fibroblasts are squeezed between tight, parallel bundles of collagen for strength when being stretched in one direction. Terms: Collagen fiber bundles, fibroblasts.

Location: Dermis of the skin (reticular region). Function: Gives strength on different direction. Note: Fibroblasts are squeezed between irregularly arranged collagen fibers, making it able to resist tension in all directions. Terms: collagen fiber bundles, fibroblasts.

Location: Walls of arteries and trachea, some parts of spine. Function: Elasticity and extensibility. Note: The collagen and fiber bundles spring back when stretched. Fibroblasts are present but not really visible. Terms: Collagen fiber bundles, elastic fiber bundles.

Location: Ends of long bone, anterior ends of ribs, end of nose. Function: Supports flexibility and movement of joints. Note: Most abundant but weakest of cartilage tissues. Matrix is formed of chondroitin sulfate. Surrounded by perichondrium, which is highly vascular tissue. The cartilage is not vascularized though. Terms: Chondroitin sulfate, chondroblasts, chondrocytes and lacunae. Perichondrium on ends.

Location: External ear, auditory tube. Function: Support and maintain shape. Note. Perichondrium is present with nearby oval-shaped chondroblasts. Round chondrocytes are found in the lacunae near the center. Terms: chondroitin sulfate, elastic fibers, chondroblasts, chondrocytes, and lacunae.

Location: Intervertebral Disc, miniscus. Function: Strong support and fusion. Shock absorption. Note: Collagen bundles make fibrocartilage is the strongest of the cartilage fibers, but has no perichondrium, which makes healing slow. Terms: Chondroitin sulfate, collagen fiber bundles, chondrocytes, and lacunae.

Location: In bones throughout the body. Function: Protection, storage, facilitates blood formation, aids in movement. Terms: Osteon, central canal, lamellae, lacunae, canaliculi, osteocytes.

Location: Blood vessels and heart. Function: RBC transport oxygen and CO2. WBC mediate allergic reactions and immune system. Platelets are essential for blood clotting. Terms: Erythrocyte (RBC), leukocyte (WBC), thrombocyte (platelets).
