The facial skeleton is composed of fourteen bones, six paired and two unpaired bones.

So far What we have discussed:

· Two nasal bones (protects the nasal cavity)

· Two maxillae (helps to make up the skull)

· Two inferior nasal conchae (helps to warm, and clean the air that passes through the nose

· Two palatine bones (It provides protection and passage for important nerves and blood vessels.)

· Two Zygomatic Bones (help create facial symmetry.)

· Two Lacrimal Bone (protects the eyeball and associated structures,)

· Mandible Bone (is the largest and strongest bone of the human face.)

Today what we will discuss is

Vomer Bone

What is Vomer Bone

The vomer is a thin, unpaired bone of the skull. Based on its appearance, its name in Latin means ‘ploughshare’. The vomer is positioned vertically in the middle of the nasal cavity. The isolated bone has two surfaces and four borders.

The main function of the vomer is to form the nasal septum together with the perpendicular plate of the ethmoid bone and the nasal septal cartilage. In addition, it provides grooves for the passageway of the neurovascular structures of the nasal cavity.

The vomer bone is a thin, flat bone that forms part of the nasal septum, which separates the left and right nasal cavities. Here are some key aspects and functions of the vomer bone:

1. **Nasal Septum**: The primary function of the vomer bone is to contribute to the structure of the nasal septum. Together with the perpendicular plate of the ethmoid bone in the midline and the septal cartilage anteriorly, the vomer forms the posterior-inferior part of the septum.

2. **Midline Structure**: The vomer bone is located in the midline of the skull, dividing the nasal cavity into left and right halves. It extends vertically from the nasal floor to the perpendicular plate of the ethmoid bone, helping to provide structural support and stability to the nasal septum.

3. **Attachment Site for Cartilage and Membranes**: The vomer bone serves as an attachment site for the septal cartilage anteriorly and the nasal mucosa (membrane lining) posteriorly. These structures help maintain the integrity and shape of the nasal septum and provide support for the nasal cavity.

4. **Articulations**: The vomer bone articulates with several other bones of the skull, including the perpendicular plate of the ethmoid bone superiorly, the palatine bones laterally, and the maxillary bones anteriorly. These articulations contribute to the overall stability and structure of the nasal septum and surrounding facial skeleton.

5. **Nasal Airflow**: The vomer bone, along with other structures of the nasal septum, helps regulate airflow through the nasal passages. It plays a role in directing and guiding airflow, as well as in warming and humidifying inspired air before it reaches the lungs.

6. **Developmental Significance**: The vomer bone undergoes ossification during fetal development and continues to grow and develop throughout childhood and adolescence. Proper development of the vomer bone is essential for normal nasal structure and function.

Overall, the vomer bone is an integral component of the nasal septum, contributing to the structural integrity of the nasal cavity and playing a role in respiratory function. Its proper development and alignment are important for overall nasal health and function.
