Cartilage Flashcards
a special form of connective tissue that also develops from the mesenchyme
cartilage
what cells are the cartilage composed of?
chondrocytes and chondroblasts
chondrocytes and chondroblast synthesize and maintain all ECM components and are located in?
lacunae
what are the functions of cartilage?
tensile strength that provides structural support for soft tissues, allows flexibility and resilient to compression
what collagen is the cartilage made up of?
type II collagen
the cartilage also contains?
hyaluronan and proteoglycans
sheath of dense connective tissue that surrounds cartilage forming an interface between the cartilage and tissues supported by cartilage
perichondrium
the cartilage in our ear is made up of?
elastic cartilage
what cartilage is found in the intervertebral disc, pubic symphysis, and meniscus?
fibrocartilage
where is the perichondrium only present?
hyaline and elastic cartilage
provides smooth low-friction surfaces in jointsl structural support for respiratory tract
hyaline cartilage
provides flexible shape and support of soft tissues
elastic cartilage
provides cushioning, tensile strength, and resistance to tearing and compression
fibrocartilage
a medical chronic condition that commonly occurs during aging, involves the gradual loss or changed physical properties of the hyaline cartilage that lines the articular ends of bones in joints
osteoarthritis
joints that are weight-bearing or heavily used are most prone to?
cartilage degeneration
most common cartilage
hyaline cartilage
covering of hyaline cartilage
perichondrium
homogenous and glassy appearance because they are rich in fibrils of type II collagen and aggrecan complexes bound in water
extracellular matrix of hyaline cartilage
similar to hyaline cartilage except it contains an abundant network of elastic fibers
elastic cartilage
contains varying combination of hyaline cartilage and small amounts of dense connective tissue; usually layered by bundled type I collagen scattered with fibroblast
fibrocartilage
semi-rigid tissue and acts as a shock absorber
cartilage matrix
the extracellular ground substance of cartilage contains what?
sulfated glycosaminoglycan and hyaluronic acid
the cartilage matrix also contains?
adhesive glycoprotein (chondronectin)
