GENERAL HISTOLOGY

Detailed explanation-1: -The parathyroid glands lie behind the thyroid. They produce parathyroid hormone, which plays a role in regulating the body’s blood level of calcium and phosphorus. Hyperparathyroidism is when your parathyroid glands create high amounts of parathyroid hormone in the bloodstream.

Detailed explanation-2: -It is shaped like a butterfly, with the right lobe and left lobe connected by a thin piece of tissue called the isthmus. The parathyroid glands are four pea-sized organs found in the neck near the thyroid. The thyroid and parathyroid glands make hormones.

Detailed explanation-3: -Parathyroid Gland Four small masses of epithelial tissue are embedded in the connective tissue capsule on the posterior surface of the thyroid glands. These are parathyroid glands, and they secrete parathyroid hormone or parathormone. Parathyroid hormone is the most important regulator of blood calcium levels.

Detailed explanation-4: -Calcium homeostasis is maintained by actions of hormones that regulate calcium transport in the gut, kidneys, and bone. The 3 primary hormones are parathyroid hormone (PTH) 1, 25-dihydroxyvitamin D-3 (Vitamin D3), and calcitonin.

Detailed explanation-5: -The parathyroid glands are two pairs of small, oval-shaped glands. They are located next to the two thyroid gland lobes in the neck. Each gland is usually about the size of a pea.
