Answer:
It arises from the ECA within the substance of the parotid gland posterior to the neck of the mandible and ascends the scalp, anterior to the ear. Within the parotid gland, the superficial temporal artery gives off the transverse facial artery, which supplies the parotid gland and duct and the masseter muscle.
