These changes are not apparent until perhaps 50 years of age as they are not perceptible. The skeletal system gradually changes over the years until it is porous and brittle, as the bones lose calcium and their density. This may be more pronounced in women with menopause.

As a result, people may become more prone to fractures, notice a decrease in height or even develop a stoop in your posture. It is very important to maintain the balance between the activities of osteoblasts and osteoclast for bone health and strength. In addition, hence, adequate calcium intake and physical activity is important in the elderly in preventing the osteoporosis. Nervous system as people age, their brain can go through natural changes. The brain and spinal cord lose nerve cells and weight. Nerve cells may begin to transmit messages more slowly than in the past. Waste products can collect in the brain tissue as nerve cells break down, causing abnormal structures called plaques and tangles to form. As nerves break down, they can affect the senses. This might have reduced or lost reflexes, awareness of pain, touch, temperature, joint position and vibration sense, leading to problems with movement and safety.
