The parietal artery is a branch of the superficial temporal artery, which is itself a division of the external carotid artery. The parietal artery supplies blood to the scalp above the ear and the lateral aspect of the head. Understanding the anatomy and blood supply to the head is critical for estheticians, especially when performing procedures that may affect the scalp or face.

The other choices refer to different arteries with distinct functions and territories. The common carotid artery is a major blood supplier to the neck and face but does not branch directly into the parietal artery. The facial artery supplies the face but does not branch into the parietal artery either. The angular artery is a continuation of the facial artery and also does not play a role in supplying the parietal area. Recognizing these relationships is important for safety during esthetic treatments and when considering the impact of procedures on vascular structures.
