Document Summary
Chapter 5: aging of the skin and musculoskeletal system. The skin provides the covering for the body and is the first line of defense against bacteria, viruses, and other type of environmental damage. The bones, ligaments, tendons, and muscles that make up the musculoskeletal system provide shape and support for the body, make movement and adjustments in position possible, and protect the internal vital organs from external trauma. The skin and musculoskeletal system provides the most obvious signs of aging, with both normal changes and disease processes. The skin, or integumentary, has several major functions. It is our front line of defense against harmful environmental influences and is an important part of our immunological and endocrine systems. The skin is critical in temperature maintenance and, in general, aids in homeostasis. Sensory nerves in the skin allow us to monitor the environment but also warn us of danger through pain.
