The pattern of the superficial arteries in the palma manus can be characterized in the following manner. In 58% of the cases the arteria ulnaris runs in an arch from the ulna to the radius and gives off a varying number of arteries to the fingers. There is no connection with any other artery. In 42% of the cases there are arterial connections, of which 32.1% are present in the form of an 'arcus' of a rather large diameter, formed through connection of the arteria ulnaris with the ramus palmaris superficialis of the arteria radialis or with the arteria metacarpalis dorsalis I. Likewise, in 9.9%, there is a connection between the arteries but this, which we call an 'anastomosis', is of a more delicate nature.
手掌部浅动脉的分布模式可通过以下方式描述。在58%的病例中，尺动脉呈弓形从尺骨走向桡骨，并向手指发出数量不等的动脉分支。与其他动脉无连接。在42%的病例中存在动脉连接，其中32.1%以直径较大的“弓”的形式存在，是通过尺动脉与桡动脉掌浅支或第一掌背动脉连接形成的。同样，在9.9%的病例中，动脉之间存在连接，但这种连接我们称之为“吻合”，其性质更为精细。
