Rear nostrils


The nose of the human throat - the front wall. The posterior nostrils and nasal cavity, lateral pharynx of the auditory trunk. At the bottom soft palate with tongue

Rear nostrils (latin choanae) - space in the head, a bone cavity opening towards the bottom. Centrally it limits and divides into even holes of the blade. In addition to it, they form the free margin of the horizontal palatal bone, the vertical plate of the same bone (its medial surface), the wing bone and the base-wedge bone, more specifically its winged tooth. A nasopharyngeal nasal duct is opened towards the nasal cavity. Bibliography
