1. | They usually include four small glands. |
2. | They are embedded in the posterior surfaces of the lateral lobes of the thyroid gland. |
3. | They secrete parathyroid hormone and calcitonin. |
4. | They play a critical role in calcium homeostasis. |

Hormones are chemical messengers of all classes except:
1. | peptide | 2. | steroid |
3. | aminated | 4. | carbohydrate |
