Nasal, Vomer, and Inferior Turbinate (Concha) Bones Anatomy

Introduction to Nasal, Vomer, and Inferior Turbinate (Concha) Bones Anatomy

  • Compared to the maxilla and mandible, the image descriptionother facial bones are relatively small and have few distinctive markings.

  • Some of the smallest are the two nasal bones, two inferior turbinates (nasal conchae), and the single vomer bone.

Sagittal view:

  1. image descriptionVomer bone – (L., – plowshare) – a thin, plow-shaped bone. The vertical plate of the vomer bone articulates with image descriptionthe perpendicular plate of the ethmoid bone to form the bony nasal septum. The septum separates the nasal cavity into two halves called nasal fossae.

  1. image descriptionInferior turbinates – are two, small bones that extend into the nasal cavity from the walls of the maxilla bones. Because of their curved shape, the turbinates are also called nasal conchae  (L., concha – shell and Gr., konche – mussel or cockle).  A thick layer of mucous membrane lines the turbinates, and the secreted mucus helps warm, humidify, and filter the air as it travels through the nasal cavity.

Inferior view:

  • The vomer bone is primarily composed of a vertical plate and two small horizontal extensions.
  1. The image descriptionvertical plate divides the nasal cavity into left and right chambers. It also partitions the posterior opening to the pharynx into left and right image descriptionchoanae (singular; choana) or posterior nares (singular; naris).
