Visual Channel

Visual Channel: Anatomy and Functions

The optic canal (Canalis opticus) is a canal that connects the eyeball to the brain and transmits the optic nerve and the ocular arterial choroid plexus. The optic canal is located at the base of the skull and is formed by an opening in the sphenoid bone (Foramen opticum).

Anatomy of the optic canal

The optic canal has the shape of a tube, which is located under the longitudinal blue sulcus of the brain. Its length is about 1.5 cm and its width is 0.5 cm. The optic canal contains the optic nerve and the ocular arterial vascular plexus, which are surrounded by special membranes - the meningeal membranes: hard, arachnoid and soft.

Functions of the visual channel

The visual channel plays an important role in transmitting information from the eyes to the brain. The optic nerve, which is located in the optic canal, transmits information about visual stimuli from the eyeball to the visual center of the brain. The visual center is located in the occipital lobe of the brain and processes information received from the eyes.

In addition, the optic canal contains the ophthalmic arteries, which provide blood supply to the eyeball. Thanks to this, the eyes receive enough oxygen and nutrients necessary for normal functioning.

Conclusion

The visual canal is an important anatomical structure that plays a key role in transmitting information from the eyes to the brain. Pathologies of the optic canal, such as tumors or inflammatory processes, can lead to impaired visual function and even loss of vision. Therefore, if any vision-related symptoms occur, you should consult an ophthalmologist for diagnosis and treatment.
