Papillary Process

The papillary processes of the paired brain, they are also called proprioceptive papillae.

The papillary part is located behind the pyramids, extends in the interpyramidal groove and ends at the junction of the pyramids above the lateral ventricle. The total length of the papillae is about 3-4 cm. There are one or two papillae. In the papilla, a final non-branching part tapering anteriorly is distinguished: a conical end and a middle segment. The posterior segment is straight and widened. The function of the conical end of the papilla is to precisely regulate the movements of the organs of the hand when palpating surrounding objects. The middle part of the papilla perceives and sends information down to the medulla oblongata and cerebellum to orient the body, maintain balance, and regulate gait. So the papilla serves as a sensor for the position of our body in space. The posterior section is a stretch receptor that unites intracranial and extracranial afferent fibers of the medial lemniscus and the pontine medulla, where they switch to neurons of the retina
