Dwarfism can be caused by the deficiency, during childhood, of:
I. | Growth hormone |
II. | Thyroid hormones |
1. | Only I and the dwarf will have normal mental development |

3. | Both I and II and in both cases the mental development will be affected |
4. | Both I and II and mental development will be effected only in II. |

II: | Thyroid hormones are most important factors that affect the process of red blood cell formation. |
III: | Thyroid hormones control the metabolism of carbohydrates but not of proteins and fats. |
IV: | Maintenance of water and electrolyte balance is also influenced by thyroid hormones. |
