Study Notes

Cartilage Structure and Composition

Composed of specialized cells called chondrocytes
Does not contain blood vessels, but receives supply through diffusion from blood vessels in the perichondrium
Contains a perichondrium

Types of Cartilage

Elastic cartilage: contains a rich network of elastic fibers, similar to glassy cartilage, with additional collagen fibers
Fibrocartilage: always associated with dense connective tissue, contains chondrocytes arranged in long rows separated by collagen fibers

Blood Cells

Cells found mainly in the blood include: Red blood cells (Erythrocytes), White blood cells (Leukocytes), and Platelets (Thrombocytes)

Monocytes

Constitute only 3-8% of the leukocytes in normal blood
Nucleus is oval or kidney-shaped
Migrate from the bloodstream to other tissues, then differentiate into tissue resident macrophages or dendritic cells
