Substance present in this area of the eye (anterior component)?
- A.
Choroid
- B.
Aqueous Humour
- C.
Cornea
- D.
Vitreous Humour
Correct Answer
B. Aqueous HumourExplanation
The aqueous humor is a clear, watery fluid that fills the anterior chamber of the eye, which is the space between the cornea and the lens. It helps maintain the shape of the eyeball, provides nutrients and oxygen to the cornea and lens, and removes waste products. The choroid is a layer of tissue in the back of the eye that supplies blood to the retina. The cornea is the transparent outer layer of the eye that helps focus light onto the retina. The vitreous humor is a gel-like substance that fills the posterior chamber of the eye, behind the lens.Rate this question:

Substance filling this cavity (posterior cavity)?
- A.
Aqueous Humour
- B.
Sclera
- C.
Retina
- D.
Vitreous Humour
Correct Answer
D. Vitreous HumourExplanation
The correct answer is Vitreous Humour. The vitreous humour is a gel-like substance that fills the posterior cavity of the eye, which is located between the lens and the retina. It helps maintain the shape of the eye and provides support to the delicate structures within the eye, such as the retina. It also helps transmit light to the retina and assists in the focusing of images on the retina.Rate this question:

- A.
Sclera
- B.
Cornea
- C.
Lens
- D.
Choroid
Correct Answer
A. ScleraExplanation
The structure being referred to in this question is the Sclera. The Sclera is the tough, white outer layer of the eye that covers most of its surface. It provides protection and support to the eye, maintaining its shape and integrity. The Cornea is the transparent front part of the eye that covers the iris and pupil. The Lens is a transparent structure located behind the iris that helps focus light onto the retina. The Choroid is a layer of tissue located between the retina and the sclera, providing nourishment to the retina.Rate this question:

What is name of this layer of the eye?
- A.
Sclera
- B.
Choroid
- C.
Retina
- D.
Superior Rectus
Correct Answer
B. ChoroidExplanation
The choroid is the layer of the eye located between the sclera and the retina. It is responsible for supplying oxygen and nutrients to the retina, which is crucial for maintaining proper vision. The choroid is also highly pigmented, which helps to absorb excess light and prevent reflection within the eye.Rate this question:

What is the name of this layer of the eye?
- A.
Sclera
- B.
Choroid
- C.
Retina
- D.
Cornea
Correct Answer
C. RetinaExplanation
The correct answer is Retina. The retina is the innermost layer of the eye that contains the light-sensitive cells called photoreceptors. These cells convert light into electrical signals that are sent to the brain through the optic nerve, allowing us to perceive visual images. The retina plays a crucial role in vision and is responsible for capturing and processing visual information.Rate this question:

What is this structure?
- A.
Pupil
- B.
Cornea
- C.
Sclera
- D.
Iris
Correct Answer
D. IrisExplanation
The given structure is the iris. The iris is the colored part of the eye that surrounds the pupil. It is responsible for controlling the size of the pupil and thus regulates the amount of light that enters the eye.Rate this question:

What is this structure?
- A.
Iris
- B.
Lens
- C.
Pupil
- D.
Cornea
Correct Answer
C. PupilExplanation
The structure being referred to in this question is the pupil. The pupil is the opening in the center of the iris, which is the colored part of the eye. It regulates the amount of light that enters the eye by adjusting its size. The other options listed, such as the lens and cornea, are also parts of the eye, but they are not specifically mentioned in the question. Therefore, the correct answer is pupil.Rate this question:

What is the name of this structure? (hint: related to blind spot)
- A.
Optic Disc
- B.
Retina
- C.
Choroid
- D.
Lens
Correct Answer
A. Optic DiscExplanation
The optic disc is the correct answer because it is a structure in the eye that is related to the blind spot. It is the point where the optic nerve exits the eye and there are no photoreceptor cells in this area, resulting in a blind spot in our visual field. The other options - retina, choroid, and lens - are also structures in the eye, but they do not specifically relate to the blind spot.Rate this question:

Fovea
Correct Answer
D. FoveaExplanation
The correct answer is Fovea. The fovea is a small, central pit in the retina of the eye. It is responsible for sharp central vision, color perception, and high visual acuity. The fovea contains a high concentration of cones, which are photoreceptor cells that are responsible for detecting fine details and colors. The other options, Optic Disc, Lens, and Sclera, are different structures in the eye but are not specifically related to the central vision and high visual acuity provided by the fovea.Rate this question:

Name of this structure?
- A.
Superior Rectus
- B.
Lacrimal Gland
- C.
Superior Oblique
- D.
Lateral Rectus
Correct Answer
B. Lacrimal GlandExplanation
The correct answer is Lacrimal Gland. The lacrimal gland is a structure located in the upper outer corner of the eye socket. It is responsible for producing tears, which help to lubricate and protect the surface of the eye. Tears also contain enzymes and antibodies that help to fight off infections. The lacrimal gland releases tears onto the surface of the eye through small ducts, allowing them to spread across the eye when we blink.Rate this question:

What is the name of this structure?
- A.
Retina
- B.
Optic Nerve
- C.
Sclera
- D.
Choroid
Correct Answer
B. Optic NerveExplanation
The given structure is named the optic nerve. The optic nerve is responsible for transmitting visual information from the eye to the brain. It is composed of a bundle of nerve fibers that carry electrical signals generated by the retina to the visual cortex in the brain, where the signals are interpreted as visual images. The optic nerve plays a crucial role in our ability to see and perceive the world around us.Rate this question:

- A.
Anterior Chamber
- B.
Posterior Chamber
- C.
Lateral Chamber
- D.
Medial Chamber
Correct Answer
A. Anterior ChamberExplanation
The correct answer is the Anterior Chamber. This compartment is located in front of the iris, which is the colored part of the eye. It is filled with a clear fluid called aqueous humor, which helps maintain the shape of the eye and provides nutrients to the surrounding tissues. The anterior chamber also plays a role in regulating intraocular pressure.Rate this question:
