The occipital artery is responsible for supplying blood to the scalp and the back of the head. It branches off from the external carotid artery and travels posteriorly, delivering oxygenated blood to the occipital region. This area includes the posterior scalp and supplies important structures that support hair follicles and skin.

The other options cover arteries with different primary functions. The temporal artery primarily supplies the lateral aspect of the head, particularly the temples. The carotid arteries, while crucial as major sources of blood to the head and neck, have several branches, each targeting specific regions. The basilar artery, on the other hand, is more associated with supplying the brain rather than the external features of the head. By understanding the specific roles of these arteries, it becomes clear why the occipital artery is associated with the blood supply to the scalp and back of the head.
