The Correct Answer and Explanation is:

Here are the labeled structures of the cow eye:

  1. Cornea – The transparent outer layer that helps to focus light entering the eye.
  2. Pupil – The black circular opening that controls the amount of light entering the eye by adjusting its size.
  3. Lens – The clear, flexible structure behind the pupil that further focuses light onto the retina.
  4. Iris – The colored part of the eye that surrounds the pupil and controls its size.
  5. Retina – The inner layer of the eye that contains photoreceptor cells (rods and cones) which detect light and convert it into electrical signals.
  6. Optic Nerve – The nerve that transmits visual information from the retina to the brain.

Not labeled:

  1. Ciliary Body – This structure produces the aqueous humor and helps to control the shape of the lens.
  2. Suspensory Ligaments – These are fibers that hold the lens in place and help it focus.
  3. Vitreous Body – A gel-like substance that fills the interior of the eye and helps it maintain its shape.

Answers to Questions 13-15:

13. What is another name for the Optic Disc?

  • Another name for the Optic Disc is the Blind Spot. This is the area of the retina where the optic nerve exits the eye. It lacks photoreceptor cells (rods and cones), so no visual information is detected in this region.

14. What is the “white part of the eye”?

  • The white part of the eye is called the Sclera. It is a tough, outer layer of tissue that helps protect the eye and maintain its shape. It is the part of the eye that you can typically see when looking at someone’s eyes.

15. What is contained in the two layers of the Retina?

  • The Retina consists of two main layers:
    1. The Outer Layer contains the Photoreceptor Cells (rods and cones). Rods are responsible for vision in low light, while cones are responsible for color vision and seeing in bright light.
    2. The Inner Layer contains Ganglion Cells, which collect visual information from the photoreceptor cells and send it to the brain via the optic nerve. The inner layer also includes supporting cells that provide nutrients and maintain the structure of the retina.
