GENERAL HISTOLOGY

Detailed explanation-1: -Keratin, a protein inside skin cells, makes up the skin cells and, along with other proteins, sticks together to form this layer.

Detailed explanation-2: -Anatomy of the skin The area that anchors the epidermis to the dermis is called the dermal-epidermal junction. It is responsible for the exchange of oxygen, nutrients and waste products between the vascularised dermis and the avascular epidermis.

Detailed explanation-3: -The epidermis is composed mainly of keratinocytes. Beneath the epidermis is the basement membrane (also known as the dermo-epidermal junction); this narrow, multilayered structure anchors the epidermis to the dermis.

Detailed explanation-4: -Dermis and hypodermis The dermis consists of dense, fibrous connective tissue whose predominant connective tissue component is collagen. The texture of collagen fibers serves as the basis for recognizing two layers of dermis.

Detailed explanation-5: -Collagen and Elastin The dermis is held together by a protein called collagen, made by fibroblasts. Fibroblasts are skin cells that give the skin its strength and resilience. Collagen is a tough, insoluble protein found throughout the body in the connective tissues that hold muscles and organs in place.
