B. Fill in the Blanks:

1. The uppermost layer of the skin is _____________.

Ans: The uppermost layer of the skin is epidermis.

2. Dermis consists of ___________ and elastin fibre.

Ans: Dermis consists of collagen and elastin fibre.

3. Melanocytes produce a black-coloured pigment called ___________.

Ans: Melanocytes produce a black-coloured pigment called melanin.

4. Langerhans are the ___________ cells found in the epidermis.

Ans: Langerhans are the immune cells found in the epidermis.

5. Dermis is the ___________ connective tissue or supportive layer of the skin.

Ans: Dermis is the fibrous connective tissue or supportive layer of the skin.

C. Subjective Questions:

1. Name the three layers of the skin.

Ans: The three layers of the skin are:

(i) Epidermis: It is the outermost or epithelial layer of the skin. It is a waterproof protective layer that covers the body and serves as a barrier to infections. It prevents loss of water from the body. The epidermis also prevents the entry of foreign bodies into the body. It does not have direct blood supply as it contains no blood vessels, and all nutrients are transferred to it from the dermis. The epidermis has three main types of cells. They are: 

(a) Keratinocytes (skin cells).

(b) Melanocytes (pigment producing cells).

(c) Langerhans (immune cells).

(ii) Dermis: It is the fibrous connective tissue or supportive layer of the skin. It lies below the epidermis. It contains blood capillaries, nerve endings, sweat glands, hair follicles, and other structures. Dermis consists of collagen and elastin fibre.

(iii) Hypodermis or subcutis: It is a layer that lies below the dermis. It is also called

subcutaneous tissue’, ‘hypodermis’ or ‘panniculus’. Subcutis mainly consists of fat cells (adipocytes), nerves and blood vessels. The fat cells are organised into lobules, which are separated by structures called ‘septae’, which contain nerves, larger blood vessels, fibrous tissue and fibroblasts. Fibrous septae may form dimples in the skin (cellulite).

2. List five functions of the skin.

Ans: Skin is the largest organ of the body. It performs key functions, resulting from multiple chemical and physical reactions taking place within it.

The basic functions of the skin are as follows:

(i) Protection: Skin protects the body from injury, heat, radiation, chemicals and microorganisms. Due to constant shedding of ‘stratum corneum’, it acts as a mechanical barrier and does not allow organisms to stay or penetrate into the skin. ‘Melanin’ produced by melanocytes present in the basal layer of the epidermis protects the body from ultraviolet radiation.

(ii) Thermo regulation: The skin also serves as a temperature regulator, enabling the body to adapt to different temperatures and atmospheric conditions by regulating moisture loss. This is done by controlling the secretion of sweat by sweat glands followed by evaporation of sweat from the surface of the skin.

(iii) Hormone synthesis: An active form of vitamin D is synthesised in the skin in the presence of sunlight.

(iv) Excretion: Through the secretion of sweat and sebum, the skin performs excretory function, eliminating a number of harmful substances resulting from metabolic activities of the intestine and liver.

(v) Immunological role: The skin plays an immunological role too as the langerhans cells pick antigens from the skin and carry them to the lymph nodes.

(vi) Sensory function: The skin has an intricate network of fine nerve terminals between epidermal cells and specialised nerve endings in the dermis and around cutaneous appendages. These nerve endings carry the sensation of touch, pain, temperature, wetness and itchiness.

A. Fill in the Blanks:

1. Cleansing is performed to remove _____________ accumulated in the skin pores.

Ans: Cleansing is performed to remove impurities accumulated in the skin pores.

2. Creams are also used to prevent the occurrence of ____________.

Ans: Creams are also used to prevent the occurrence of blackheads.

3. Moisturisers delay the formation of _____________.

Ans: Moisturisers delay the formation of wrinkles.

4. The pH of ____________ skin ranges from 5.5 to 5.8.

Ans: The pH of normal skin ranges from 5.5 to 5.8.

5. Dry skin is because of lack of lubrication from the _____________ gland.

Ans: Dry skin is because of lack of lubrication from the sebaceous gland.

6. Oily skin has a tendency of developing open pores, ____________ and blackheads.

Ans: Oily skin has a tendency of developing open pores, pimples and blackheads.

7. A __________ mask is used for tightening the skin and promoting blood circulation.

Ans: A peel-off mask is used for tightening the skin and promoting blood circulation.
