Masseteric Artery

The masseteric artery and its branches.

The Masseteric Artery is a small artery in the human body that plays a crucial role in the circulatory system. It is a branch of the maxillary artery, which is itself a major branch of the external carotid artery. The masseteric artery is responsible for supplying blood to the masseter muscle, a large muscle in the jaw that plays a key role in mastication (chewing).

Anatomy

The masseteric artery originates from the second part of the maxillary artery, also known as the pterygoid part. It runs laterally, crossing the mandibular condyle to reach the deep surface of the masseter muscle, which it supplies with oxygenated blood. It also sends branches to the temporomandibular joint and the parotid gland.

Clinical Significance

Knowledge of the masseteric artery's anatomy is crucial in several surgical procedures, including maxillofacial surgery and plastic surgery. Damage to the masseteric artery during surgery can lead to significant bleeding and postoperative complications.
