Document Summary
Physical changes and age-related health conditions: the body. All three layers of skin get thinner and are less able to heal. Skin elasticity is reduced due to changes in the top two layers (epidermis and dermis) Reduction in tactile sensory perception (discriminating sensations) Drier skin due to decrease in sebum production. Skin abnormalities (rough plaques of skin cells) Hair loss (destruction of germ centers that produce follicles) Graying (white) caused by cessation of pigment production. Uv rays of the sun accelerate process of cross-linking. Shingles: reactivation of the varicella-zoster virus that goes dormant after having chicken pox. No cure, but shingles vaccine reduces risk. Due to chronic sun exposure plus the skin"s diminished resiliency and reduced ability to heal. Melanoma is the most aggressive but also the least common tends to be more common among oas due to the cumulative effect of uv sun exposure across their lifespan. Bones, muscles, joints, connective tissues (ligaments, tendons, cartilage)
