Excision and localisation of the avian (Gallus domesticus) carotid body.

The anatotopography of cranial thoracic inlets, the carotid body and associated structures in the caudal pole of the thyroid gland are described. The source from which the various groups of fowls (n = 65) were obtained as well as the varied localisation of the carotid body are indicated. In this investigation, the carotid body was found to be situated mostly (49 cases) either on or in the immediate vicinity of blood vessels (carotid and inferior thyroid artery) and only in 14 cases in close association with the parathyroids.
