 The sole function of the parathyroid gland is to maintain [[Calcium|calcium homeostasis]]. Calcium homeostasis is, amongst other things, important for maintaining the function of the [[Nervous and Special Senses - Anatomy & Physiology#Nervous System|nervous]] and [[Musculoskeletal System Overview - Anatomy & Physiology|muscular]] systems. When blood calcium levels drop below a certain point, calcium-sensing receptors in the parathyroid gland are activated to release [[Hormones - Anatomy & Physiology|hormone]] into the blood. The hormone produced by the parathyroid gland (Parathyroid Hormone) also has an effect on [[Phosphorus|phosphorus homeostasis]].

-The parathyroid glands are multiple (generally four) small glands, approximately 1-2mm in length are located about the cranial trachea. Generally, there are two internal glands embedded within the [[Thyroid Gland - Anatomy & Physiology|thyroid Glands]], and two external glands are outside the thyroid tissue. However, all of the parathyroid tissue may be embedded within the thyroid gland itself. In the Horse, there are 'nests' of parathyroid tissue along the neck to the thoracic inlet.
