As with all Korean family names, the holders of the Hong surname are divided into different patrilineal clans, or lineages, based on their ancestral seat.

pons. 1. any slip of tissue connecting two parts of an organ. 2. that part of the central nervous system lying between the medulla oblongata and the midbrain, ventral to the cerebellum; see brainstem.. [TA] In neuroanatomy, the pons varolii or pons cerebelli; that part of the brainstem between the medulla oblongata caudally and the mesencephalon rostrally, composed of the basilar part of pons and the tegmentum of pons.
The pons is part of the brainstem, and in humans and other bipeds lies between the midbrain (above) and the medulla oblongata (below) and in front of the cerebellum.The pons is also called the pons Varolii (bridge of Varolius), after the Italian anatomist and surgeon Costanzo Varolio (1543â75).This white matter includes tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.The pons in humans measures about 2.5 cm or 1 inch in length. Most of it appears as a broad anterior bulge rostral to the medulla.his white matter includes tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.
