Ana Lab - CARTILAGE

Cartilage

consists of cells called Chondrocytes

Chondrocytes and Chondroblasts

Cells in cartilage. Synthesize and maintain all ECM components, located in matrix cavities (lacunae)

Tensile Strength, Structural support for soft tissues, allows flexibility without distortion, resilient to compression

roles of Cartilage

Cartilage

made up off Collagen Type 2 (car2lage)

Cartilage receives blood supply

Perichondrium

Sheath of Dense Connective Tissue that surrounds cartilage in most places, forming an interface between the cartilage and the tissues supported by the cartilage

Hyaline, Elastic, Fibro

Types of Cartilage

elast

cartilage in ear

hyaline cartilage

nose, joint, coastal, articular cartilage

Fibro Cartilage

Intervertebral disk, knee joints

Hyaline Cartilage

provides smooth, no friction surfaces in joints (upper respiratory tractt etc)

Elastic Cartilage

provides flexible shape and support of soft tissues

Fibro Cartilage

provide cushion and tear resistance

Osteoarthritis

chronic condition that commonly occurs during aging, gradual loss or changed physical properties of the hyaline cartilage (knees, and hips, weight bearing joints, wrist, fingers, heavily used)

Hyaline Cartilage

most common type of cartilage, homogenous (nose, larynx, trachea, bronchi)

Elastic Cartilage

Auricle of the ear, walls of external auditory canals, surrounded by perichondrium  

Fibrocartilage

dense connective tissues

Cartilage Matrix

produced and maintained by chondrocytes and chondroblasts, semi-rigid, has adhesive
