2 lis 2024 · The thyroid gland is an endocrine structure located in the neck. It plays a key role in regulating the metabolic rate of the body. In this article, we shall look at the anatomy of the thyroid gland – its position, blood supply, and clinical correlations.
14 cze 2023 · Unlike other endocrine glands that secrete their products directly into the bloodstream, the thyroid gland stores its products in follicles. The follicles are often clustered together to form numerous lobules that forms the parenchyma of each lobe of the thyroid.
The thyroid is supplied with arterial blood from the superior thyroid artery, a branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk, and sometimes by an anatomical variant the thyroid ima artery, [4] which has a variable origin. [10]
24 lip 2023 · The inferior thyroid artery is considered the principal blood supplier of the thyroid gland. The ITA gives rise to the ascending cervical artery, the inferior laryngeal artery, and also gives pharyngeal, tracheal, and esophageal branches.
24 lip 2023 · The thyroid gland has an extremely rich blood supply and is estimated to be six times as vascular as the kidney and relatively three to four times more vascular than the brain. It receives blood from the superior and inferior thyroid arteries.
6 lis 2024 · This rich blood supply is essential for the gland’s endocrine function, as it ensures the efficient release of hormones into the bloodstream. Arteries: Superior Thyroid Artery: Arising from the external carotid artery, the superior thyroid artery supplies the upper portions of the thyroid gland. It descends to the gland, giving off multiple ...
For what may concern the blood supply, it is achieved through two superior thyroid arteries (STA), two inferior thyroid arteries (ITA), and sometimes by an additional artery, the thyroid ima artery (TIMA) that reaches the gland from below at the isthmus level.
