Study Notes
Nutrients Affecting Bone Growth and Maintenance
- Vitamin D is necessary for the process of bone formation
- Vitamin C becomes part of the collagen in bone matrix
- Calcium becomes part of the salts of bone matrix
- Phosphorus becomes part of the salts of bone matrix
- Protein is crucial for bone structure
Hormones Affecting Bone Growth and Maintenance
- Growth hormone increases protein synthesis and energy production from food
- Insulin helps maintain a stable bone matrix
- Calcitonin decreases the reabsorption of calcium from bones
- Thyroxine increases protein synthesis and the rate of mitosis of chondrocytes in cartilage
- Parathyroid hormone increases the reabsorption of calcium by the small intestine and kidneys
- Estrogen or testosterone increases energy production from glucose
