Presentation transcript. parathyroid glands: • the parathyroid glands are small in size and are found on the posterior aspect of the thyroid gland. • typically, there are four of them but the actual number may vary. histology of the parathyroid • the endocrine cells within these glands are arranged in thick, branching cords containing.

Follow. the parathyroid glands are small endocrine glands located on the thyroid gland that secrete parathyroid hormone (pth) to regulate calcium levels. primary hyperparathyroidism is usually caused by a solitary parathyroid adenoma. pre operative localization with sestamibi scanning is accurate for adenomas.
