Arteria angularis

Arteria Angularis is a significant artery in the human body, specifically located in the facial region. It is the terminal part of the facial artery, which is a branch of the external carotid artery. The arteria angularis is responsible for supplying blood to the side of the nose and the medial canthus of the eye.

Anatomy

The facial artery gives rise to the arteria angularis at the level of the lower border of the nose. It ascends along the side of the nose and terminates at the medial canthus of the eye. The arteria angularis is closely related to the nasal artery and the infraorbital artery, both of which contribute to the blood supply of the facial region.

Function

The primary function of the arteria angularis is to supply oxygenated blood to the side of the nose and the medial canthus of the eye. It also contributes to the blood supply of the upper lip and the lower eyelid. The arteria angularis plays a crucial role in maintaining the health and function of these facial structures.

Clinical Significance

Due to its location and function, the arteria angularis can be involved in several medical conditions. For instance, trauma to the face can lead to injury of the arteria angularis, resulting in bleeding or hematoma. In addition, conditions that affect the blood vessels, such as atherosclerosis or vasculitis, can also involve the arteria angularis.
