Integumentary System MBLEX Latest Update Graded A+ Understanding the Functions of the Skin Grasp the fundamental roles of the skin, such as regulating body temperature and shielding against pathogens and injuries. The skin, which spans about 20 square feet, acts as the body's largest organ, protecting against microbes and environmental elements, maintaining body temperature equilibrium, and facilitating sensations of touch, heat, and cold. Epidermis The outermost skin layer acts as a barrier against water and determines skin pigmentation. Dermis Located beneath the epidermis, this layer contains strong connective tissue, hair follicles, and sweat glands. Hypodermis 2 Deeper subcutaneous tissue primarily composed of fat and connective tissue. Understanding Skin Nerve Supply Recognize the specific patterns through which skin receives nerve supply. Dermatomes correspond to areas of skin supplied by individual spinal nerves, conveying sensory information like pain, temperature, itch, and touch to the brain via dorsal roots. Dermatomes are crucial in neurology for pinpointing spinal injury locations. Skin Appendages Structures associated with the skin serving specialized functions such as sensation, movement, lubrication, and heat regulation. Common human skin appendages include hairs (for sensation, heat regulation, and protection), arrector pili muscles (smooth muscles that raise hairs), sebaceous glands (which secrete sebum onto hair follicles to lubricate), sweat glands (producing sweat with various odors), and nails (providing protective functions). Understanding the Effects of Massage/Bodywork on the Integumentary System 3 - Supports skin vitality and elasticity. - Transmits sensory signals to the brain through skin receptors, promoting overall body relaxation. - Enhances skin texture by removing dead cells and improving circulation. - Aids in tissue regeneration, which is beneficial for healing burns, wounds, and reducing wrinkles. - Stimulates blood and lymphatic circulation to nourish the skin.
