Optic Chiasm a Gland or do the Nerves Twist

[biferi]

Right infront of the Pituitary Gland is the Optic Chiasm.

Now I know when the Right and Left Optic Nervs come into the Brain they Cross here.

But is this Optic Chiasm a Gland or do the Nervs Twist or what is it?

Some of the axons from the left eye go to the right thalamus, and some of the axons from the right eye go to the left thalamus.

Thanks but do the Nervs physicly Cross?

The nerves do fuse at the chiasm. However, each nerve is a bundle of axons, and I'm not sure of the detailed arrangement of the axons from each eye within the chiasm.

they don't merge together into one entity if that's what you are asking. They are more like a local road and a high way right on top of it.
