Study Notes

Loose Connective Tissue Proper

Predominant cell type is fibroblasts, which produce fibers and ground substance.
Loose connective tissue features a flexible and irregular arrangement of fibers, aiding in support and elasticity.

Adipose Tissue

Commonly found in subcutaneous regions, around organs, and in bone marrow.
Primary function is energy storage, providing insulation and protection to organs.
Also helps in thermoregulation and cushioning against mechanical shocks.
Predominant cell type is adipocytes, specialized for fat storage.

Areolar Tissue

Characterized by a loose arrangement of fibers and abundant ground substance.
Commonly located beneath epithelial tissues and surrounding organs.
Functionally supports and binds tissues together while allowing for flexibility.

Reticular Tissue

Composition includes a network of thin, branching reticular fibers made of collagen.
Commonly found in lymphoid organs such as lymph nodes and the spleen.
Primary function is to provide a supportive framework for organs.

Dense Connective Tissue

Dense regular connective tissue is found in tendons and ligaments, providing strong attachment points.
Dense irregular connective tissue features collagen fibers arranged in various directions, offering strength against multidirectional forces.
Elastic connective tissue consists primarily of elastic fibers, enabling stretch and flexibility, commonly found in large arteries and lung tissue.

Specialized Connective Tissue

Three types include cartilage, bone, and blood.
Cartilage is typically found in joints, the ribcage, and the nose.
Primary cell type in cartilage is chondrocytes, which maintain the extracellular matrix.
Cartilage’s resilient quality is due to its high water content and presence of proteoglycans.

Hyaline Cartilage

Commonly found in the trachea, larynx, and articular surfaces of joints.
Characterized by a smooth matrix which facilitates frictionless movement.
Surrounded by perichondrium, providing nutrients and support.
Primary function is to reduce friction and absorb shock at joints.

Elastic and Fibrocartilage

Elastic cartilage is found in structures requiring flexibility, such as the ear and epiglottis.
Distinguished by a dense network of elastic fibers, allowing it to return to shape after deformation.
Fibrocartilage is located in intervertebral discs and the pubic symphysis, providing strength and shock absorption due to its dense collagen fiber composition.

Bone Tissue

Hardness and rigidity are due to hydroxyapatite crystals, primarily calcium phosphate.
Well vascularized, allowing for efficient nutrient distribution and bone remodeling.
Main composition includes an organic matrix (collagen) and mineral components (calcium and phosphorus).

Blood

Thrombocytes are also known as platelets, essential for blood clotting.
Red blood cells (erythrocytes) are responsible for oxygen transport throughout the body.
Fibers are primarily needed during clot formation to stabilize the blood clot.
White blood cells (leukocytes) are crucial for immune response, providing defense against pathogens.
