, The Skin
• The integument system consists of the skin (cutaneous
membrane) and its accessory organs.
• The skin is composed of three layers of tissue: the
outer epidermis (made of stratified squamous
epithelium ), the middle dermis (made of fibrous
connective tissue ), and the inner subcutaneous layer
or hypodermis (made of adipose tissue and loose
connective tissue).
• Accessory organs include the hair (hair root and hair
shaft) , hair follicle , pili arrector muscle, sebaceous
gland , sudoriferous gland , nails , and mammary
gland.
