Pna, Bna? Canalis Orbitoethmoideus, Jna)

Introduction:
In the human orbit, there are many anatomical structures that ensure the normal function of the eye and its surrounding tissues. One such structure is a canal in the medial wall of the orbit known as the Canalis Orbitoethmoideus, or more commonly known as Pna, Bna; Canalis Orbitoethmoideus, Jna).

Description:
Canalis Orbitoethmoideus is a narrow canal located in the suture between the frontal and ethmoid bones of the orbit. This canal is the pathway that leads to the posterior cells of the ethmoid bone. The posterior cells of the ethmoid bone are a system of air-filled cavities and are part of the orbital cavity.

Function:
Canalis Orbitoethmoideus plays an important role in the transmission of neural and vascular structures that are essential for normal ocular function. One of the most significant elements passing through this canal is the posterior ethmoidal nerve (Jna). The posterior ethmoidal nerve is a branch of the trigeminal nerve and innervates the posterior part of the orbit. It transmits sensory information from the eye to the brain and plays an important role in visual function.

In addition to the posterior ethmoid nerve, blood vessels also pass through the Canalis Orbitoethmoideus, which provide oxygen and nutrients to the posterior cells of the ethmoid bone. These vessels play an important role in maintaining healthy surrounding eye tissue and ensuring its normal function.

Conclusion:
Canalis Orbitoethmoideus (Pna, Bna; Canalis Orbitoethmoideus, Jna) is a canal in the medial wall of the orbit that plays an important role in the transmission of the posterior ethmoidal nerve and vessels ensuring normal ocular function. Understanding the anatomy and function of this canal is important for medical professionals such as ophthalmologists and surgeons to effectively diagnose and treat various diseases and disorders associated with the eye and its surrounding structures. Further research and study of Canalis Orbitoethmoideus may lead to increased knowledge of the orbit and lead to improved treatment and care of the visual system.

Pna, bna – canalis orbitoethmoideoi sjna (canal in the medial wall of the orbit (in the suture between the frontal and ethmoid bones), leading to the posterior cells of the ethmoid bone; the place of passage of the posterior ethmoidal nerve and the vessels of the same name). This is a bony opening leading into the orbit through the dura mater. It is located in the upper wall of the internal orbital canal between the orbit and the pyramids of the temporal bones.
