Anatomically, the model gives both an insight into many of the structures found in the orbit, but can also be used to understand the structure of the orbit, with its many bony components.
The model shows the structure of the eyeball with its different layers:
The outermost layer is made up of the transparent cornea, which at the limbus is connected to the sclera (the white tendon that makes up the back 5/6).
The middle layer (called the uvea) which consists of the iris (rainbow) incl. the pupil, the corpus ciliare (the ray body) of which the ciliary muscle is primarily seen and the choroid (the choroid).
The innermost layer is called the retina.
The outermost layer of the eyeball can be halved and removed, so that the vitreous body (corpus vitreum) and the lens become visible.
Furthermore, it can be seen how the optic nerve (N. opticus) leaves the eyeball at the back, as well as the crossing of the optic nerve (chiasma opticus).
On the outside of the white tendon membrane (sclera) you can see the 6 striated muscles that control eyeball movements. These are divided into the 4 straight muscles (musculi recti) and the 2 oblique muscles (musculi obliqui).
