The human skull

[Fishnoodler]

Is the eyesocket totally encased at the back separating the the back of the eye from the brain, If so how thick is the bone?

[ChuckFickens]

yep totally encased, the optic nerve is a magic nerve that can go through bone.

Ok then let me rephrase the question, How big is the hole at the back compared the the front of the eyesocket?

[ChuckFickens]

very small.

Just about big enough for the optic nerve as it goes.

Fishnoodler,,,,the optic nerve is not the only structure that has to get into the eye socket, there are also many nerves that come from the brain and pass to the muscles of the eye and they pass through a structure called the superior orbital fissure which is long and at least times the size of the optic foramen.

the following pass through it

Lachrymal nerve
Frontal nerve
Trochlear nerve
Superior orbital nerve
Nasociliary nerve
Inferior orbital nerve
Abducent nerve

In that order from inside to outside.
