Mesenchyme
Connective Tissue
Proper
Dense
Regular
Primarily parallel collagen fibers. Withstands great tensile stress when pulling force is applied in one direction. Tendons, most ligaments. Attaches muscles to bones or to other muscles.
Elastic
Dense regular connective tissue containing high proportion of elastic fibers. Allows recoils of tissue following stretching. Walls of large arteries, within the walls of the brachial tubes. Maintains pustule floe of blood through arteries.
Irregular
Primarily irregularly arranged collagen fibers. Major cell type is fibroblast, few elastic fibers. Found in the dermis of the skin. Major cell type is fibroblast. Some elastic fibers.
Loose
Areolar
gel like matrix with all three fiber types. plays important role in inflammation. wraps and cushions organs. Widely distributed under epithelia of body.
Adipose
Packed adipocytes, or fat cells. Insulates against heat loss and protects organs. Within abdomen and in breasts. Under the skin, around kidneys and eyeballs.
Reticular
Network of reticular fibers in a typical loose ground substance. Fibers form a soft internal skeleton that supports other cell types. Found in Lymphoid organs.
Cartilage
Hyaline
Amorphous but firm matrix. Supports and reinforces, serves as resilient fusion resists compressive stress. Covers the ends of long bones in joint cavities. Forms costal cartilage of the ribs.
Fibrocartilage
Matrix similar to but less firm than matrix in hyaline cartilage. Tensile strength with ability to absorb compressive shock. Found between vertebrae. Thick collagen fibers predominate.
Elastic
Similar to byline cartilage, but more elastic fibers in matrix. Maintains the shape of a structure while allowing great flexibility. Supports the external ear.
Bone
Hard calcified matrix containing many collagen fibers. Very well vascularized. Provides structural strength. Supports and protects (by enclosing). Stores calcium and other minerals and fat. Marrow inside is the site for blood cell formation.
Blood
Red and white blood cells in a fluid matrix (Plasma). Transport of respiratory gases, nutrients, wastes, and other substances. Contained within blood vessels.
