C. Subjective Questions:

1. Name and describe the three layers of the skin.

Ans: The skin consists of three layers— epidermis, dermis and hypodermis or subcutis. Epidermis is the topmost layer of the skin, whereas, subcutis or hypodermis is the bottom layer. Subcutis is also known as the ‘fat layer’. It provides physical protection and serves as an energy reservoir. Besides, it helps in insulation and thermal regulation of the body.

2. State any three functions of the skin.

Ans: Some of the major functions that the skin performs are as follows:

(i) Protection: The most important function of the skin is to protect the body from injury, heat, radiation, chemicals and microorganisms. The outermost layer of the epidermis is covered with ‘sebum’, which makes it waterproof. The acid mantle of the sebum makes it resistant to microorganisms. Melanin produced by melanocytes, which are present in the basal layer of the epidermis, protects the body from ultraviolet rays.

(ii) Sensation: The skin responds to heat, cold, touch, pressure and pain due to the presence of sensory nerve endings.

(iii) Absorption: The skin can absorb only certain drugs, medicines and creams. It implies that substances can enter the body through the skin.

3. Describe the functions of the epidermis.

Ans: The epidermis is the topmost or epithelial layer of the skin. It forms an outer protective covering of the body. It prevents loss of water from the body. The thickness of the epidermis varies in different body parts, for example, it is thickest on the palms and soles and thinnest on the eyelids.

The epidermis contains no blood vessels but has many small nerve endings. Since it does not have direct blood supply, all nutrients are supplied to it from the dermis.

The epidermis is made up of several layers of cells, mainly keratinocytes, melanocytes, and Langerhans cells.

(i) Keratinocytes: These cells become more mature or differentiated and accumulate ‘keratin’ as they move outwards. They eventually fall or rub off.

(ii) Melanocytes: These are found in the basal layer of the epidermis. These cells produce a black pigment called ‘melanin’, which imparts colour to the hair, skin and eyes. Melanin is packaged into small parcels (melanosomes), which are transferred to keratinocytes. Melanin protects the skin against ultraviolet rays.

(iii) Langerhans: cells These are also called ‘immune cells’. The langerhans cells are found in the epidermis and help the body recognise allergens (materials that are foreign to the body).
