Study Notes
Eye Anatomy and Function
- Anterior chamber: The fluid-filled space located between the cornea and the iris.
- Iris: A structure that regulates the amount of light entering the posterior segment of the eye.
- Aqueous humor: Found in the anterior and posterior chambers of the eye.
True/False Statements
- The iris does not divide the eye into anterior and posterior segments (false).
- The pupil cannot adjust its size independently of the iris (false).
Fibrous Layer
- The fibrous layer consists of the sclera and cornea.
- Sclera: The largest portion of the fibrous layer.
- Cornea: The first structure that allows light to enter the eye.
Visual Pathway
- Optic nerve: The cranial nerve that transmits visual information from the eyeball to the brain.
Observations in Cow Eye
- The fibrous layer can be observed entirely from the superficial surface of the cow eye (true).
Muscular Structures
- Ciliary body: The muscular structure responsible for anchoring the lens in place.
Eye Interiors
- Vitreous body: Located in the posterior segment of the eye, it provides structural support.
- Retina: Identifies the neural layer of the eye.
- Choroid: Recognized as the highly vascular structure of the eye.
Additional Eye Features
- Optic disc: Known as the blind spot; a region sensitive to light absence.
- Vitreous body mischaracterization: Incorrectly stated to consist of a thin, watery fluid.
