GENERAL HISTOLOGY

Detailed explanation-1: -The thyroidea ima a. was found to arise from the brachiocephalic trunk, and bifurcated into two branches almost immediately after its origin. These branches ascended in front of the trachea and entered the bases of the right and left lobes of the thyroid gland.

Detailed explanation-2: -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.

Detailed explanation-3: -The inferior mesenteric artery (IMA) comes off the abdominal aorta a few inches below the takeoff of the superior mesenteric artery (SMA). The artery runs slightly lateral to the abdominal aorta after its origin at the level of the third lumbar vertebrae behind the third part of the duodenum.

Detailed explanation-4: -The thyroid ima artery (thyroidea ima artery, arteria thyreoidea ima, thyroid artery of Neubauer or the lowest thyroid artery) is an inconstant (10%) unpaired artery supplying the thyroid gland. The artery also supplies the trachea, the parathyroid gland and the thymus gland (as thymica accessoria) in rare cases.
