What part of the body does the external carotid artery NOT supply?

• A. Scalp
• B. Face
• C. Hindbrain
• D. Neck

Answer: (C)

The external carotid artery primarily supplies blood to the face, scalp, and neck. It branches into several arteries that deliver oxygenated blood to various tissues and structures in these regions. Notably, the external carotid artery's branches include the facial artery, superficial temporal artery, and maxillary artery, which are instrumental in vascularizing the facial area and scalp.

In contrast, the hindbrain, which includes parts such as the cerebellum, brainstem, and lower portions of the brain, is primarily supplied by the vertebral arteries and the basilar artery rather than the external carotid artery. Thus, it does not receive blood supply from the external carotid artery, making this choice the correct answer in the context of the question.
