Integumentary System

       The integumentary system has three major regions; Epidermis, Dermis, and Hypodermis. The epidermis is composed of keratintized stratified squamous epithelium, consisting of four distinct cell types and four or five layers. This layer is the outer portion of the skin, its exposed to the external environment and functions in protection. The dermis is the second major skin region containing strong, flexible connective tissue. It is composed of two layers; papillary and reticular. Then the hypodermis is the subcutaneous layer deep to the skin. It is composed of adipose and areolar connective tissue. Here are a couple of power points that we have done about the integumentary system.
