Eye

Eye

• Protection:

  • Measures taken to prevent harm, damage, or injury.

• Cornea:

  • The transparent, front part of the eye covering the iris and the pupil, responsible for focusing light into the eye.

• Aqueous Humor and Vitreous Humor:

  • Aqueous Humor: The clear, watery fluid in the front part of the eye, helping to maintain the eye's shape and nourish the cornea and lens.

  • Vitreous Humor: The gel-like substance filling the back part of the eye, providing support to the retina.

• Pupil:

  • The adjustable opening in the center of the iris through which light enters the eye.

• Zonula Ciliaris:

  • A ring of fibers connecting the ciliary body to the lens, involved in adjusting the shape of the lens for focusing.

• Sclera:

  • The tough, white outer layer of the eye, maintaining the eye's shape and providing protection.

• Optic Nerve:

  • The nerve that carries visual information from the retina to the brain.

• Retina:

  • The light-sensitive tissue lining the back of the eye, containing photoreceptor cells (rods and cones) that convert light into nerve signals.

• Rods:

  • Photoreceptor cells in the retina responsible for vision in low-light conditions and detecting shades of gray.

• Cones:

  • Photoreceptor cells in the retina responsible for color vision and detecting fine details in bright light.

• Blind Spot:

  • The area on the retina where the optic nerve exits the eye, lacking photoreceptor cells, resulting in no vision at that point.

• Tapetum:

  • A reflective layer in the eyes of some animals, enhancing low-light vision by reflecting light back through the retina.

• Lens:

  • A transparent, flexible structure in the eye that focuses light onto the retina by adjusting its shape.

• Conjunctiva:

  • The thin, transparent membrane covering the front of the eye and the inner surface of the eyelids
