ABSTRACT
The major blood vessels of the ostrich wing were studied by dissection of the wings of 8 ostriches. The axillary artery entered the caudo-ventral aspect of the wing and divided into the brachial and deep brachial arteries. The deep brachial artery gave rise to the radial and ulnar collateral arteries which supplied the caudodorsal aspect of the brachium. The brachial artery divided in the cubital fossa into the smaller ulnar and large radial arteries. The ulnar artery supplied the cranio-ventral aspect of the antebrachium and manus, and the radial artery the caudo-ventral and dorsal aspects of the antebrachium and manus, including the feathers. With few exceptions the veins corresponded with the arteries that supplied the region they drained. The basilic vein passed along the cranial margin of the wing, unaccompanied by arteries or nerves, to drain the major part of the wing. The brachial artery and the basilic veins were the vessels most accessible for arterio- and venipuncture, respectively.

The exact location of the urethral diverticulum of the bull was determined. It was found to lie 80-100 mm caudal to the colliculus seminalis, at the transition from the pelvic to the penile urethra. The presence of the diverticulum makes catheterization of the urinary bladder via the penile urethra very difficult.

The techniques used in investigations undertaken to study the arterial blood supply of the brain of domestic ruminants are described and evaluated. These include various coloured intravascular injections, corrosion preparations, injection of contrast media for angiography and clearing of tissues.

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.
