Question

Quizplus · Accepted Answer

The underlying dermis is a thick layer of connective tissue that contains collagen and elastin fibers, as well as water and jellylike materials that make the skin compressible. Collagen fibers help prevent tearing of the skin, and elastin is a flexible fiber that makes the skin resilient. Distributed throughout the dermis are blood vessels, lymph vessels, muscle cells, hair follicles, and sebaceous and sweat glands. Sweat glands are exocrine glands. About 95% of the cells in the epidermis are keratinocytes. The other 5% of epidermal cells are pigmented cells, or melanocytes. The subcutaneous layer contains fat cells, which provide insulation and serve as a depository for reserve calories. It also contains blood vessels, nerves, and the base of the appendages of the skin (such as hair follicles).
