Savannah Henry · Answer 1

True

Explanation:

The fibrous layer is the external layer of eyeball wall. The fibrous layer is a connective tissue that is not connected with blood supply thus it is avascular tissue. This tissue contains eyeball contents. The opaque sclera consist of around 90% of posterior side of fibrous layer. The cornea consist of around 10% of fibrous anterior portion of eye. The layers like neural and fibrous are deep. Thus, it is not possible to observe these layers. So, only the fibrous layer can be observed in its entirety from the superficial surface of the cow eye.

Camilla Lin · Answer 2

True

Explanation:

Three layers are found in a given mammalian eye and since cow is also a mammal the same applies to it.

The three layers are as follows:

1. Fibrous layers - it is the outermost layer that consists of the sclera and the cornea.

2. The vascular layer - it is the middle layer and is vascularized. it consists of the iris, the ciliary body, and the choroid.

3. The neural layer - it is the innermost layer that consists of the retina.

In a cow's eyes, these three layers are present however only the uppermost fibrous layer is visible from the superficial surface because the vascular and the neural layers lie deep to the fibrous layer.
