Verified step by step guidance
1
Step 1: Begin by identifying the external carotid artery, which is a major artery that supplies blood to the face, scalp, and oral cavity. It branches off from the common carotid artery.
Step 2: Understand that the external carotid artery has several branches, including the facial artery, maxillary artery, and superficial temporal artery, among others.
Step 3: Focus on the superficial temporal artery, which is one of the terminal branches of the external carotid artery. It specifically supplies blood to the scalp and parts of the face.
Step 4: Compare the superficial temporal artery to other options provided in the question. The internal carotid artery primarily supplies blood to the brain, the vertebral artery also supplies blood to the brain, and the facial artery supplies blood to the face but not the scalp.
Step 5: Conclude that the superficial temporal artery is the correct answer because it is a major branch of the external carotid artery and supplies blood to both the scalp and parts of the face.
