|---|---|
| Calcitonin | promotes calcium deposition in bone and inhibits osteoblast activity |
| growth hormone | stimutlates liver to produce the hormone somatomedin, which causes cartilage proliferation (Wucherung) at epiphyseal plate and resulting bone elongation |
| parathyroid hormone | increases blood calcium levels by encouraging bone resorption |
| sex hormones (estrogen and testosterone) | stimulate osteoblasts; promote epiphydeal plate growth and closure |
| thyroid hormone | stimulates bone growth by stimulating metabolic rate of osteoblasts |
| Vitamin A | activates osteoblasts |
