One of these crosses the root of the nose, and anastomoses with the angular artery.

The greatest contribution is from the facial artery which traverses the face obliquely and terminates in the angular artery.

The external nose is supplied with blood by the facial artery, which becomes the angular artery that courses over the superomedial aspect of the nose.

Angular: The angular artery is a significant terminal branch of the anterior or middle trunk of the MCA.

The facial artery supplies the platysma and goes on as the angular artery, which connects with the branches of the arteria supratrochlearis and arteria infraorbitalis.

The middle trunk that exist in parts of the population, when present provides the pre-Rolandic, Rolandic, anterior parietal, posterior parietal and the angular artery for irrigation instead of the upper and lower trunks.

The angular artery is the terminal part of the facial artery; it ascends to the medial angle of the eye's orbit, imbedded in the fibers of the angular head of the Quadratus labii superioris, and accompanied by the angular vein.

The nasolabial flap is a random flap that is emplaced with the proximal (near) portion resting upon the lateral wall of the nose, and the distal (far) portion resting upon the cheek, which contains the main angular artery, and so is perfused with retrograde arterial flow.

The inferior palpebral arch anastomoses, at the lateral angle of the orbit, with the lower of the two lateral palpebral branches from the lacrimal and with the transverse facial artery, and, at the medial part of the lid, with a branch from the angular artery.
