Arterial supply to the adrenal gland in the house musk shrew (Suncus murinus).

Branching patterns of the adrenal artery exhibit interspecies and individual variations. As Eulipotyphla species have distinctive morphological characteristics, observations in this group may provide insights into the comparative anatomy of this artery. This study used 15 house musk shrews (Suncus murinus). In most cases, adrenal arteries arose from a single parent artery, namely the caudal phrenic artery, abdominal aorta, or renal artery. In one left case, adrenal arteries emerged from both the abdominal aorta and renal artery. The most common pattern of adrenal arterial supply was one middle and one caudal adrenal artery on both sides, with no cranial one. The house musk shrew exhibited a simpler branching pattern than other species, offering comparative anatomical insights into the adrenal artery.
