The Parathyroid Reflex
The parathyroid glands consist of two pairs, a superior and an inferior, that sit on the back of the thyroid gland. The parathyroid glands produce the hormone PTH, or parathyroid hormone. PTH deals with the balance of calcium and phosphate in the blood. Under the correct circumstance, the parathyroid hormone absorbs calcium and phosphate from the GI tract, moving these minerals into the blood.
Calcium and Phosphate
Calcium and phosphate are structural components of bones and teeth. Phosphate works within the body structure performing a number of tasks, combining with other minerals to make DNA and RNA. Calcium is absorbed into the bloodstream. This absorption is controlled not only by the parathyroid hormone, but also by vitamin D, which enters our bodies through sunlight and food.
If the calcium level drops, PTH increases, allowing calcium to be released from the bones directly into the bloodstream. The opposite occurs if the calcium level is too high. Calcium is essential for many bodily functions, including blood clotting, muscle contraction, normal heartbeat, and nerve health.
The parathyroid also affects the kidneys. PTH speeds up the removal of calcium from the urine to the blood. At the same time, it accelerates the arrival of phosphate from the blood to the urine. Therefore PTH increases calcium in the blood and decreases the level of phosphate in the blood.
Finding the Reflex
The reflexes for the parathyroids are found to the side and slightly under the thyroid reflex. As you look at the bottom surface of the great toe, exactly at the neck reflex, the parathyroid reflex overlaps with this reflex and the thyroid reflex as well. Thumb walk under the fat pad of the great toe right along the edge near the centerline. The second lobe reflection is found at the bottom of the thyroid reflex, along the base of the toe neck. Thumb walk in and hold, and rotate and hold, letting the thumb stay exactly on the point.
