GENERAL HISTOLOGY

Detailed explanation-1: -The areolar tissue is also dense with collagen fibres, which makes it strong and rigid. The areolar connective tissue lies deep under the epidermis and is important for keeping the skin flexible and elastic.

Detailed explanation-2: -Elastin, like collagen, is a protein which is a major constituent of the ECM of connective tissue.

Detailed explanation-3: -Elastic fibres are found in the articular fibrous tissue of various joints, and in the fibrous perichondria of hyaline and fibrous cartilages. Within bones, elastic fibres are found in the outer fibrous layer of the periosteum, but not in the inner cellular (cambial) layer.
