Overview of cartilage types.
Cartilage can be classif
ed into three types (hyaline, elastic, and f
brocartilage) based on
the characteristics oF the matrix.

Hyaline
cartilage
Type II collagen
Mostly in groups
(isogenous groups)
Yes, except
articular
cartilage surFace
Trachea,
bronchi,
ventral ends
oF ribs, nose,
articular ends and
epiphyseal plates
oF long bones
ConFers shape and
fl exibility (respiratory
tract); Forms cartilage
model For bone growth in
the Fetus; Forms smooth
surFace to provide Free
movement in joints
Elastic
cartilage
Type II collagen
and elastic f bers
Mostly in groups
(isogenous groups)
Yes
Epiglottis, larynx,
pinna oF the ear,
and auditory canal
and tube
ConFers shape and
elasticity
±ibrocartilage
Type II and type I
collagen
Most are small and
sparsely arranged
in parallel columns
or rows
No
Articular disks,
intervertebral disks,
pubic symphysis,
and the insertion oF
tendons
Provides resistance to
compression, cushioning,
and tensile strength
