The aim of this study was anatomical and comparative examination of vascular sources and angioarchitecture of the amygdaloid body in adult man and sheep. The studies were carried out using own injection method. The cerebral arteries filled with synthetic many-colored latex were dissected under an operating microscope. It was found that the main source of vascularization of the amygdaloid body, both in the human and sheep brains, is formed by 1-3 branches originating from the proximal segment of the middle cerebral artery. The supplementary sources are singular small branches of the anterior choroidal artery. Each of these arborescent arterioles distributes and supplies only the amygdaloid body and does not penetrate into the surrounding white matter. Their courses and topography do not create anatomical conditions for collateral circulation. Obtained results indicate also that the amygdaloid body, as a unit structure of the cerebral gray matter, possesses its own, separate and well developed arterial system.
本研究的目的是对成年男性和绵羊杏仁体的血管来源和血管构筑进行解剖学及比较研究。研究采用自行注射法进行。在手术显微镜下解剖充满合成多色乳胶的脑动脉。结果发现，在人类和绵羊大脑中，杏仁体血管化的主要来源是由大脑中动脉近端段发出的1 - 3支分支形成。补充来源是脉络丛前动脉的单个小分支。这些树枝状小动脉中的每一支仅分布并供应杏仁体，不穿透周围的白质。它们的走行和局部解剖结构并未为侧支循环创造解剖条件。所获结果还表明，杏仁体作为脑灰质的一个单位结构，拥有自身独立且发育良好的动脉系统。
