(BQ) Part 2 book "Textbook of human histology (with colour atlas and practical guide) presents the following contents: Skin and its appendages, the cardiovascular system, the cardiovascular system, digestive system - oral cavity and related structures, digestive system - oesophagus, stomach and intestines, hepatobiliary system and pancreas, the urinary system,. | Chapter 12 Skin and its Appendages SKIN e skin forms the external covering of the body. It is the largest organ constituting 15-20 of total body mass. TYPES OF SKIN ere are two types of skin. in or hairy skin In this type of skin epidermis is very thin. It contains hair and is found in all others parts of body except palms and soles Plate . ick or glabrous skin In this type of skin epidermis is very thick with a thick layer of stratum corneum. It is found in palms of hands and soles of feet and has no hair Plate . STRUCTURE OF SKIN e skin consists of two layers A super cial layer the epidermis made up of strati ed squamous epithelium A deeper layer the dermis made up of connective tissue Fig. . e dermis rests on subcutaneous tissue subcutis . is is sometimes described as a third layer of skin. In sections through the skin the line of junction of the two layers is not straight but is markedly wavy because of the presence of numerous nger-like projections of dermis upwards into the epidermis. ese projections are called dermal papillae. e downward projections of the epidermis in the intervals between the dermal papillae are sometimes called epidermal papillae Fig. .

Here the elevations form characteristic epidermal ridges or rete ridges Fig. that are responsible for the highly speci c ngerprints of each individual. The Epidermis e epidermis consists of strati ed squamous keratinised epithelium Fig. . Fig. Section .
