Lower nasal concha
The lower nasal concha, concha nasalis inferior, the steam room, is a curved bone plate and has three processes: lacrimal and latticed.
The maxillary processus maxillaris forms an acute angle with the bone; In this angle is the lower edge of the maxillary cleft. The appendix is clearly seen from the side of the maxillary sinus after its opening.
The lacrimal process , processus lacrimalis, connects the inferior nasal concha with the tear bone.
The latticed process, processus ethmoidalis, departs from the jaw joint with the bone and protrudes into the maxillary sinus. It often fuses with the hook-shaped process of the latticed bone .
The lower sink with the anterior part of the upper margin is strengthened on the shell crest of the upper jaw , crista conchalis maxillae, and the posterior part is on the shell ridge of the perpendicular plate of the palatine bone , crista conchalis lamini perpendicularis os palatini. Under the lower shell there is a longitudinal slit - the lower nasal passage, meatus nasi inferior.
