"Cartilage" is generally a semi-solid and flexible material, which is present between the bones of organisms.
Extra Information :-
~~~~~~~~~~~~~~~~
Cartilage is surrounded by a sheath of dense fibrous connective tissues known as "Perichondrium".
The cells of Cartilage are known as "Chondrocytes".
The Chondrocytes secrete a flexible matrix, known as "Chondrin".
"Chondrin" is a "Mucoprotien".
Cartilage is "Avascular" (not vascular).
Nutrients diffuse into the cartilage from the nearby tissues.
Blood vessels do not grow into the cartilage because Chondrocytes produce a chemical called "Antiangiogenesis factor".
"Antiangiogenesis factor" is a "Potential anti-cancer agent".
Answer:
Some additional parts of the skeleton which are not as hard as bones and are elastic in nature and can be bent are called cartilages, e.g. cartilage of ear.
