Document Summary
Appendages: hair, nails, glands (sweat including mammary gland, sebaceous. The skin is composed of several tissues: epidermis. Super cial, thin, and keratinized strati es squamous epithelium: dermis. Deep, thick, papillary layer (loose connective tissue), reticular layer (dense irregular connective tissue: subcutaneous layer (hypodermis) Deep to the skin, thick and well nourished individuals and in those living in cold climates. 90% of the cells of the epidermis. Have long processes that project between neighbouring keratinocytes and transfer melanin granules to them. The number of melanocytes is about the same in all people, di erences in skin colour are due mainly to the amount of pigment melanocytes produce and transfer to keratinocytes. Exposure to ultraviolet (uv) light increases melanin production to protect against. Have long processes and participate in immune responses against microbes that invade the skin. Located in the deepest layer of the epidermis. In contact with a process of a sensory neuron.
