3.1 Describe the principal constituents of the skin.
The constituents of the skin are made up of three main parts. The epidermis, dermis and the hypodermis. Each part play an important role to the build up of the skin.
The outer layer of skin is the epidermis, this serves as a protective layer to the layers underneath and is made up of a type of body tissue called stratified, squamous, eptithelium and comprises of five layers.
The layer found underneath the epidermis is the dermis. This layer is an elastic network made up of collagen and contains blood vessels, lymph vessels, nerves, sweat glands and oil glands. The dermis features two separate layers: The capillary layer and the reticular layer.
The capillary layer is positioned directly underneath the epidermis and contains cone like projections that extend upward into the epidermis, otherwise known as the papillae. Nourishment is provided by the blood vessels to the living cells in the lower layers of the epidermis, whilst cellular waste is removed by the lymph vessels.
The reticular layer is dense and fibrous and contains blood and lymph vessels, fat cells, sweat and oil glands, hair follicles and arrector pili muscles attached to the hair follicles. The fibres help to support the other structures and allow the skin to flex and move. The fibres in the dermis are known as connective tissue.
If you were to look even further then you would find a layer called the hypodermis or the subcutaneous or sometimes even the fatty layer. This layer is characterized by closely packed fat cells. The subcutaneous tissue comprises fatty tissue known as adipose, and gives the body smoothness and shape. This tissue contains stored fat which is burned up to create energy. It also performs the function of a protective cushion for the outer skin. Its thickness varies according to the sex, age and health of the person in question.
All the layers mentioned above build up to form the constituents of the skin.
DO you think that sounds right??? x
