The thyroid, or thyroid gland, is an endocrine gland in vertebrates. ... They consist of a rim that has a rich blood supply, nerve and lymphatic presence, ...
The thyrocervical trunks supply the thyroid gland and some scapular muscles. [1] Structure. The thyrocervical trunk is a branch of the subclavian artery. [1]
The thyroid ima artery (thyroidea ima artery, arteria thyroidea ima, thyroid artery of Neubauer or the lowest thyroid artery) is an artery of the head and neck.It is an anatomical variant that, when present, supplies blood to the thyroid gland primarily, or the trachea, the parathyroid gland and the thymus gland (as thymica accessoria) in rare cases.
The parathyroid gland produces and secretes parathyroid hormone in response to low blood calcium, which plays a key role in regulating the amount of calcium in the blood and within the bones. Parathyroid glands share a similar blood supply, venous drainage, and lymphatic drainage to the thyroid glands.
The left and right brachiocephalic veins (previously called innominate veins) are major veins in the upper chest, formed by the union of the ipsilateral internal jugular vein and subclavian vein (the so-called venous angle) [1] behind the sternoclavicular joint. [2]
The inferior thyroid veins appear two, frequently three or four, in number, and arise in the venous plexus on the thyroid gland, communicating with the middle and superior thyroid veins. While the superior and middle thyroid veins serve as direct tributaries to the internal jugular vein , the inferior thyroid veins drain directly to the ...
Thyroid gland. follicular cells of the thyroid gland produce and secrete T 3 and T 4 in response to elevated levels of TRH, produced by the hypothalamus, and subsequent elevated levels of TSH, produced by the anterior pituitary gland, which further regulates the metabolic activity and rate of all cells, including cell growth and tissue ...
The parathyroid artery is the single individual artery that provides oxygenated blood supply to the parathyroid glands. [1] While studies have concluded that most subjects' parathyroid glands are supplied by the thyroid arteries, up to 45% have been determined to have a "distinct anastomosing branch between the inferior and the superior thyroid ...
