ARTERIAL VASCULARIZATION OF THE THYROID GLANDS IN BIRDS (GALLUS GALLUS DOMESTICUS) OF THE HUBBARD LINEAGE
Keywords:
vase, origin, orderingAbstract
The behavior of the arteries destined for the thyroid glands was studied, addressing their number, origin and ordering in 30 birds, Gallus gallus domesticus, of the Hubbard lineage through injection through the right ischial artery of a solution of colored Neoprene latex 450, fixation in an aqueous solution of form 10% through intramuscular, intracavitary and subcutaneous injection and subsequent dissection. The thyroid glands receive collaterals from the arteries: common carotid, ascending esophageal, common vagus nerve, ingluvial and vertebral trunk ipsilaterally, with the left gland also receiving collaterals from the vertebral artery. The number of vessels varies from 1 to 5 in both antimeres. The right gland receiving 1 vessel in 1 case (3.33%) will be called the thyroid artery, 2 vessels in 6 cases (20%) called the cranial and caudal thyroid arteries, 3 vessels in 11 cases (36.66%) called the thyroid artery cranial, middle and caudal arteries, 4 vessels in 9 cases (30%) called cranial, middle cranial, middle caudal and caudal arteries and 5 vessels in 3 cases (9.99%) called cranial, middle cranial, middle, middle caudal and flow rate. For the left gland we found 1 vessel in 1 case (3.33%), 2 vessels in 8 cases (26.66%), 3 vessels in 10 cases (33.33%), 4 vessels in 7 cases (23.33 %) and 5 vessels in 4 cases (13.33%).
