LECTURE 1 cartilage (connective tissue type) Flashcards
cartilage qualities
more abundant prenatally; firm, flexible, resists compression, durable; avascular (condrocytes can function with low oxygen); not innervated
cartilage cells (2)
chondroblasts, condrocytes
chondroblasts
produce cartilage
chondrocytes
mature cartilage cells (in lacunae)
cartilage fibers
all types have collagen fibers, elastic cartilage also has elastic fibers
endochondralossification
creation of bone from cartilage
lacunae
spaces in the matrix
perichondrium
dense irregular connective tissue around cartilage; function: growth/repair of cartilage (chondroblasts); resists expansion during compression of cartilage
types of cartilage (3)
hyaline, elastic, fibrocartilage
hyaline cartilage
most abundant; collagen fibers in matrix; support via flexibility/resilience; glossy in color/appearance; eg: at limb joints, ribs, nose, trachea, larynx
elastic cartilage
many elastic fibers in matrix with collagen; great flexibility; eg: external ear, epiglottis
fibrocartilage
collagen fibers densely interwoven; resists both compression and tension (super strength); eg: meniscus, annulus fibrosus
