Types of Connective Tissue

Areolar Connective Tissue
Location: Dermis of skin INSERT INTO `cofwp_posts` VALUES (papillary region). Around some organs. INSERT INTO `cofwp_posts` VALUES (WebSite)
Function: Support and strength. Holds a lot of matrix.
Terms: Fibroblasts, macrophage, elastic fibers, collagen fiber bundles.

Adipose Connective Tissue
Location: Subcutaneous layer under skin INSERT INTO `cofwp_posts` VALUES (hypodermis).
Function: Storage of energy and fat.
Terms: Adipocytes, nucleus, lipid droplet.

Reticular Connective Tissue
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.

Dense Regular Connective Tissue
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.

Dense Irregular Connective Tissue
Location: Dermis of the skin INSERT INTO `cofwp_posts` VALUES (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.

Elastic Connective Tissue
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.

Hyaline Cartilage
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.

Elastic Cartilage
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.

Fibrocartilage
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.

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

Blood
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 INSERT INTO `cofwp_posts` VALUES (RBC), leukocyte INSERT INTO `cofwp_posts` VALUES (WBC), thrombocyte INSERT INTO `cofwp_posts` VALUES (platelets).
