Superior Thyroid Artery

The Superior Thyroid Artery (pronunciation: su·pe·ri·or thy·roid ar·ter·y) is one of the main arteries that supply blood to the thyroid gland. The term originates from the Latin words 'superior' meaning 'higher', 'thyroid' referring to the 'thyroid gland', and 'artery' meaning 'a vessel that carries blood from the heart to the body'.

Anatomy

The Superior Thyroid Artery is the first branch of the external carotid artery. It descends to the upper pole of the thyroid gland, supplying it with oxygenated blood. Along its course, it gives off several branches including the infrahyoid, sternocleidomastoid, and superior laryngeal arteries.

Function

The primary function of the Superior Thyroid Artery is to provide oxygenated blood to the thyroid gland, which is essential for the gland's normal function. The thyroid gland uses this blood supply to produce thyroid hormones, which play a crucial role in the body's metabolism, growth, and development.
