Elastic cartilage (Terminologia histologica: Cartilago elastica)
is characterised by the presence of many elastic
fibres in the ground substance
of the cartilage and therefore has a slight yellowish colour and some opacity.
Elastic cartilage has a good elastic distortion capacity and flexibility.
Its cells, the chondrocytes and -blasts (latter more active) are similar
to those of hyaline cartilage, but they
are more often seen singly lying in the cartilage cavities. They synthethise
substance with less chondroitin sulfate and masked collagen
fibres that are not visible in light microscopy. The elastic fibre
meshwork is mainly present in the interterritorial substance, i.e. between
the groups of cells, and continiues into the perichondrium.
The elastic meshwork is detectable even without special
stain for elastic fibres. There are few locations where elastic
cartilage is present: the epiglottis, the corniculate and
cartilages as well as the vocal process of the
of the larynx, the cartilage of the outer ear (Cartilago auriculae)
and the external auditory tube (Meatus acusticus externus), the
auditory tube (Tuba auditiva), and the wall of smallest
of the lung.
