functions of cartilage
Answers
Answer:
Hi there!
Cartilage is one of the connective tissue, that is compact, less vascular and very flexible. The bones found in joints and discs between vertebral are the example ofcartilage. Functions of cartilage are: (1)It provides support and flexibility to body part. (2) It smoothens surface at joints.
Cartilage function is more than structural, and has different functions in the life cycle. In the embryo, it provides support and is a precursor to bone. Embryonic cartilage either remains as cartilage or provides a substructure for endochondral ossification, meaning it also functions as a template for the rapid growth and development of the musculoskeletal system.
Cartilage is a supple tissue which allows for facial movement as well as providing a lightweight supportive structure in the external ear, and the tip and septum of the nose. In other regions it acts as a shock absorber, cushioning areas where bone meets bone and preventing abrasion and damage. A joint would also not be able to bend without the flexibility of cartilage. A combination of roles is seen in the airways, where cartilage rings around the trachea prevent collapse and damage, and cartilage at the ends of the ribs allows the ribcage to swing upwards and outwards during inspiration. Cartilage also plays a role in bone repair where, as in the embryo, it provides a template for ossification, this time to broken sections of bone.
