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 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 hypophyseal portal system is a system of blood vessels in the microcirculation at the base of the brain, connecting the hypothalamus with the anterior pituitary.Its main function is to quickly transport and exchange hormones between the hypothalamus arcuate nucleus and anterior pituitary gland.
The thyrocervical trunk soon divides into branches: the inferior thyroid artery, the suprascapular artery, and the transverse cervical artery. [2] The transverse cervical artery is present in about 2/3 of cases. In a third of cases the superficial cervical artery and the dorsal scapular artery arise as the transverse cervical artery. [3]
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into interstitial spaces where they are absorbed into blood rather than through a duct. The major glands of the endocrine system include the pineal gland , pituitary gland , pancreas , ovaries , testes , thyroid gland , parathyroid gland ...
The branches to the gland are generally two in number. One, the larger, supplies principally the anterior surface; on the isthmus of the gland it connects with the corresponding artery of the opposite side. A second branch descends on the posterior surface of the gland and anastomoses with the inferior thyroid artery. Besides the arteries ...
The inferior thyroid artery is an artery in the neck. It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle . It then turns medially behind the carotid sheath and its contents, and also behind the sympathetic trunk , the middle cervical ganglion resting upon the vessel.
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 ...
