Final answer:
Aging causes thinner tissues, decreased muscle tone, stiffer joints, muscle atrophy, and impaired cellular regeneration due to shorter telomeres.
Step-by-step explanation:
Changes noted in aging associated with collagen fiber diameters and fibril concentrations include thinner and drier tissues, reduced elasticity, wrinkles, and potential for high blood pressure. Additionally, aging can lead to decreased muscle tone, gray hair due to less melanin production, and reduced sensory capabilities necessitating the use of glasses and hearing aids. Bones may lose calcium, decreasing overall height, while fluid loss in the spinal cartilage disks and stiffer joints is also common.
Muscles undergo atrophy, and there is an overall decrease in mass. At the cellular level, telomeres shorten, impairing cellular regeneration and contributing to age-related diseases such as arthritis, memory issues, and certain cancers.Aging is associated with changes in the collagen fiber diameters and fibril concentrations. Some of the changes noted in aging include:Collagen fibers decreasing in connective tissue, leading to a loss of elasticity in the skin and other tissues.Muscle tone being lost, resulting in a flabby face.Joints losing cartilage and stiffening.
