The vomer.
That would be the vomer.
The inferior portion of the nasal septum in the back is formed by the perpendicular plate of the ethmoid bone and the vomer bone. These bones help to separate the left and right nasal cavities and contribute to the structure of the nasal septum.
Vomer
The vomer is the inferior bone of the nasal septum. It is located in the midline of the nasal cavity, separating the left and right nostrils. The vomer articulates with the ethmoid bone superiorly and the maxillary bone anteriorly.
The inferior nasal concha, a separate bone from the ethmoid bone, forms the most inferior turbinates in the nasal cavity.
Vomer Bone
That's correct. The vomer is a thin, flat bone that forms the lower and posterior part of the nasal septum, helping to separate the left and right nasal cavities in the skull.
Vomer, a facial bone, and Ethmoid bone, a cranial bone, form the nasal septum
The nasal septum is formed by the perpendicular plate of the ethmoid bone, the vomer, and the septal cartilage.
The nasal cavity is divided by the midline by the nasal septum, which is composed of bone and cartilage. This structure separates the cavity into right and left sides.
The primary bone in the septum of the nose is called the vomer bone. The other bone in the nasal septum is called the ethmoid bone.
The structure separating the nostrils is called the nasal septum. It is composed of bone and cartilage and helps to divide the two nasal passages.
