Abstract The systemic arterial pattern of the guinea pig was studied to determine the arrangement of the major arterial trunks and their branches. Fifty‐nine specimens were examined by dissection, angiography, and corrosion casting. The arterial arrangement was found to resemble a typical mammalian pattern, although some exceptions were noted. For example, the internal carotid arteries were small and of questionable significance in the cerebral blood supply. Instead, a major portion of the blood supply to the brain appeared to be provided by the internal ophthalmic arteries. In the thoracic region, large dorsal scapular arteries originated and were distributed in part to the large fat pad in the dorsal cervical region. Also, each vertebral artery arose as two separate rami that anastomosed a few millimeters from their origin. The arterial pattern of the thoracic limb presented no unusual features.
