Above the ear is generally the temporal part, the temporal bone itself belongs to the structure of the skull, the relative temporal bone is relatively thin, if the impact of external forces may also lead to fractures, thus causing a series of cranio-cerebral damage, so above the ear is a relatively important part. Generally, if you have an argument with others, it is best not to touch this part, otherwise it may cause damage to the brain parenchyma and serious complications. For the ear, you should also pay attention to prevention and try not to inflame the ear, otherwise it may also cause intracranial infections, which can lead to serious complications. The lower part of the ear is generally the temporomandibular joint area.
