You probably mean arteria temporalis as to the one that is supplying top of the head and skull, but isnt it coming as an extension of the main carotid artery, which is the one supplying the brain with its internal branch and the outer head/skull with the external branch. I think this whats seen in the two pictures above, all three of them should be there. Im not sure if the external carotid and temporal arteries are the main or the one supplying that microvasculature on top of head or there are other ones involved.
Yes, arteria temporalis = superficial temporal artery. Yes, it's an extension of the common carotid artery, which then branches off into the internal (brain) and external (outside of head) carotid arteries.
The brain is supplied directly by the internal carotid arteries and the vertebral arteries, which supplies other extremely large arteries in the brain - so the brain is completely saturated with blood. There is no major artery on the scalp, it is supplied by microvasculature extending from the superficial temporal arteries. The issue isn't with major blood delivery through the arteries, that is usually fine unless people are super sick and probably dying. The issue is when the extension of microvasculature into the scalp from the artery - which requires more fine tuning and is a more adaptive and plastic structure for proper oxygen/nutrient/blood delivery. The other external artries mostly supply to the side and back of the head, but not to the top of the head as much.
There are a few arteries that can supply some of the scalp that come from the internal carotid, but they are mostly used for supplying blood to the eyes and forehead, with only very little going to the scalp.
