- 9.1: Bone Structure and Function
- This page covers the skeletal system, which consists of 206 bones providing support, organ protection, and mineral storage. It explains the two main types of bone tissue: trabecular and cortical, and describes the dynamic remodeling process involving osteocytes, osteoclasts, and osteoblasts. Additionally, it emphasizes the importance of nutrients like calcium and vitamin D in maintaining bone health, adapting to mechanical stress, and mineral balance.
- 9.2: Micronutrients Essential for Bone Health - Calcium and Vitamin D
- This page examines the vital roles of calcium and vitamin D in the body, highlighting calcium's functions in bone health, nerve transmission, muscle function, and blood clotting, along with the hormonal regulation of calcium levels. It discusses the significance of vitamin D in promoting calcium absorption and outlines dietary sources for both nutrients.
- 9.3: Other Essential Micronutrients for Bone Health
- This page outlines essential nutrients for bone health, focusing on vitamins and minerals such as calcium, phosphorus, magnesium, vitamin K, and fluoride. It highlights their roles in bone structure, metabolism, and overall health, emphasizing the importance of a varied diet over supplements.
- 9.4: Osteoporosis
- This page covers osteoporosis, a condition marked by significant bone loss and higher fracture risk, especially in women. It details how bone density is assessed via DEXA scans and the T-score classification. Risk factors are divided into unmodifiable (age, sex, family history) and modifiable (lifestyle choices). Prevention strategies focus on a calcium and vitamin D-rich diet, regular weight-bearing exercise, and measures to prevent falls.
