Question

Dermis of the skin is formed of
(a)Adipose connective tissue
(b)Epithelial tissue
(c)Muscular tissue
(d)Areolar connective tissue

Answer 1

This is a specialized tissue consisting of lipid-rich cells called adipocytes. As it comprises about 20-25% of total body weight in healthy individuals. The main function of this tissue is to store energy in the form of lipids (fat).

Complete answer:
The dermis layer of the skin is subcutaneous. This layer is composed of adipose connective tissues. Adipose connective tissue is a fat-storing tissue that helps in the prevention of heat loss from the body of the animal. So the correct answer is 'Adipose connective tissue'.

Additional Information: -The epidermis has no blood supply and depends on diffusion from the dermal cells for all its metabolic needs.
-The dead-cell layer of the stratum corneum protects from a water loss that allows the vertebrates to dwell on land.
- Keratin, produced in migrating epidermal cells, forms the basis of nails in our fingers, feathers, and beaks of birds and other epidermal derivatives.
-The epidermis is thickest on the friction surfaces and thinnest over the eyelids, on the lower parts of the abdomen, and around the external genitalia.
-The epidermis consists of a living malpighian layer, in contact with the basement membrane (which is attached to the dermis), and a superficial horny layer of dead cells. The malpighian layer consists of both the stratum basale and the stratum spinosum of the epidermis layer.
So, the correct answer is, ‘Adipose connective tissue.’

Note: The epidermal cells, which multiply chiefly at the base in contact with the dermis, gradually ascend to the surface, manufacturing keratin as they go and finally die in the upper part, forming a horny layer.
