the eyeball is completely surrounded
byhalia of soft fatty tissue and placed within
a bony orbit their I is protected
seeing from inside the predicted position
above the eyeball within it's fun and sheep i thought id
is shown still more clearly note that
this is a white stock called optic nerve
which connects the a to the brain and also
these muscles which mu the eyeball this
is the empty I socket within the skull with its bony wall

and Aborn orbit in front
the caps you love the eyeball seems to have

within
this transparent budging portion is called the cornea
that is also a crystalline lens which is one of the main parts
