The pericentral lobule (lat. l. paracentalis) is an anatomical structure located in the posterior central part of the facial part of the skull, as well as at the base of the pyramid of the temporal bone, on its frontal and parietal surfaces. Coincides with the initial part of the pituitary gland. This type of lobule is associated with the degree of development in a person near the central lobe of the hearing organ - the auricle. In contrast, the lobule of the outer ear is the only replaceable structure. Anatomists had a long-standing view of the appearance of lobules around the ears dating back to the 6th century BC. As for the ear replacement apparatus and its parts, it plays a certain role in the relative position. In particular, the last positions of the individual elements are observed along the midline, touching the lateral surface in this case of the lobes of the outer ear. The functionality of this near-central lobe is also important, so one of the blood vessels that supply blood to the ears rests
