Block of the Superior Oblique Muscle of the Eyeball (Trochlea, Pna, Bna, Jna)

The trochlea of ​​the superior oblique muscle of the eyeball (trochlea, pna, bna, jna) is a fibrocartilaginous ring that is part of the structure of the orbit. It is attached to the trochlear fossa or spine on the anteromedial part of the superior wall of the orbit and plays an important role in eye movement.

Within the trochlea of ​​the superior oblique muscle of the eyeball lies the superior oblique muscle tendon, which controls the movement of the eye upward and towards the nose.

This muscle is one of the six extraocular muscles and is found in the orbit along with other muscles, nerves and blood vessels.

The block of the superior oblique muscle of the eyeball plays an important role in maintaining the correct position of the eye and controls its movements. If the superior oblique muscle block of the eyeball is damaged or does not function properly, it can lead to blurred vision and other eye problems.

Surgical treatment of superior oblique muscle trochlea injuries may include reconstruction of the muscle or replacement of the damaged ring.

Overall, the superior oblique muscle block is an important part of the eye structure and plays an important role in maintaining eye health and proper vision.

Title: Block of the Superior Oblique Muscle of the Eyeball (Trochlea, Pna, Bna, Jna)

The trochlea of ​​the superior oblique muscle of the eyeball (trochlea, pna, bna, jna) is a fibrocartilaginous ring attached to the trochlear fossa or spine on the anteromedial part of the superior wall of the orbit, through which the tendon of the superior oblique muscle of the eyeball passes. The superior oblique muscle block plays an important role in the movement of the eyeball by ensuring the correct position and function of the superior oblique muscle. Damage or abnormal development of the block can lead to disturbances in eye movements and diplopia. Anatomically, the block of the superior oblique muscle is located deep in the orbit, so injuries to it are rare. Nevertheless, knowledge of the structure and functions of this formation is important for understanding the biomechanics of the oculomotor system.
