Posterior temporal artery

Posterior Temporal Artery

The arteries of the face and scalp. (Posterior temporal artery labeled at center right.)

The Posterior Temporal Artery is a branch of the Superficial Temporal Artery that supplies blood to the posterior part of the scalp. It is a vital component of the circulatory system in the human body.

Structure

The Posterior Temporal Artery arises from the Superficial Temporal Artery, which is itself a branch of the External Carotid Artery. It travels upwards and backwards to supply the posterior part of the scalp. It is accompanied along its course by the Auriculotemporal Nerve.

Function

The primary function of the Posterior Temporal Artery is to supply oxygenated blood to the posterior part of the scalp. It also plays a role in thermoregulation, helping to control the temperature of the scalp.

Clinical significance

Knowledge of the Posterior Temporal Artery is important in surgical procedures involving the scalp or skull, as damage to this artery can lead to significant blood loss. It may also be involved in conditions such as Temporal Arteritis, a form of vasculitis that can lead to headaches, scalp tenderness, jaw pain, and even vision loss.
