Perpendicular plate

Perpendicular Plate

The Perpendicular Plate is a significant anatomical structure found in the human body. It is a part of the Ethmoid Bone, which is one of the bones that make up the Skull. The Perpendicular Plate contributes to the formation of the Nasal Septum, which divides the Nasal Cavity into two halves.

Structure

The Perpendicular Plate is a thin, flattened lamina arranged in a vertical direction. It forms a part of the nasal septum, with one surface facing the nasal cavity and the other facing the Nasal Fossa. The upper border of the Perpendicular Plate articulates with the Cribriform Plate, while the lower border merges with the Vomer and the Palatine Bone.

Function

The primary function of the Perpendicular Plate is to support the nasal septum. This, in turn, helps in the division of the nasal cavity, facilitating the separate passage of air through each nostril. The Perpendicular Plate, along with other structures of the nasal septum, also aids in directing the flow of air and filtering out dust and other particles.

Clinical Significance

Damage or deviation of the Perpendicular Plate can lead to a condition known as a Deviated Septum. This condition can cause problems with normal airflow, leading to symptoms such as difficulty in breathing, nasal congestion, and recurrent sinus infections.
