lacrimalartären
The lacrimal artery is a crucial blood vessel in the anatomy of the eye. It originates from the ophthalmic artery, which itself is a branch of the internal carotid artery. The lacrimal artery typically travels along the superior border of the lateral rectus muscle. Its primary role is to supply blood to the lacrimal gland, the structure responsible for producing tears. Beyond the lacrimal gland, it also provides nourishment to surrounding structures. These include the conjunctiva, eyelids, and the lateral rectus muscle itself. The lacrimal artery often gives off branches that contribute to the vascularization of the orbital tissues. In some anatomical variations, it may be the sole artery supplying the lacrimal gland. Understanding the course and distribution of the lacrimal artery is important in ophthalmology and neurosurgery, particularly when considering surgical approaches to the orbit or conditions affecting tear production.
