Question

Which of the following is lack of blood supply?

1) Bone 2)Cartilage 3)Connective Tissue 4)All of given options

Answer 1

Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural). Nutrition is supplied to the chondrocytes by diffusion. The compression of the articular cartilage or flexion of the elastic cartilage generates fluid flow, which assists diffusion of nutrients to the chondrocytes.
