What does the sclerotic layer in the eye do?
This is the outermost layer of the eye excepting the cornea. It is composed of dense fibrous tissue to protect the internal eye structures and is also where the external ocular muscles insert to allow you to move your eyes.
What is the outer eye?
The outer eye refers to the visible part of the eye, including the eyelids, lashes, and outer corner structures. It provides protection for the more delicate internal structures of the eye, such as the cornea, iris, and lens. The outer eye also plays a role in lubricating the eye through tear production.
What is orbital radiography?
Orbital radiography is a medical imaging technique used to visualize the bones and soft tissues of the eye socket (orbit) and surrounding structures. It helps in the diagnosis of fractures, infections, tumors, and other conditions affecting the eye and its surrounding structures.
What does the fluid filled chamber do in the eye?
The fluid-filled chamber in the eye helps to maintain the shape of the eye and supports the structures within it. It also helps to nourish the eye by supplying nutrients and removing waste products. Additionally, the fluid plays a role in maintaining the eye's internal pressure for proper function.
True or false some proteins within a cell can be viewed with the naked eye?
False. Proteins are typically not visible to the naked eye as they are microscopic in size. They can only be visualized using specialized techniques such as microscopy or biochemical assays.
What is used to to visualized the internal structures of the eye?
the pupil
What is function of the ora serrata?
Secretes aqueous humor to provide nutrients to the internal structures of the eye.

Why do scientist need a microscope to look at eukaryotic cells?
Eukaryotic cells are small and have internal structures that can only be viewed at high magnification. Microscopes allow scientists to see these structures in detail, such as the nucleus, mitochondria, and other organelles, which are crucial for understanding cell function. Without a microscope, these structures would be too small to see with the naked eye.
What is orbital radiography?
Orbital radiography is a medical imaging technique used to visualize the bones and soft tissues of the eye socket (orbit) and surrounding structures. It helps in the diagnosis of fractures, infections, tumors, and other conditions affecting the eye and its surrounding structures.
What drops are used to dilate the eyes?
Eye drops containing medications such as tropicamide or phenylephrine are commonly used to dilate the eyes for medical examinations or procedures. These drops work by causing the muscles in the iris to relax, allowing the pupil to open wider and let more light in for better visualization of the eye's internal structures.
What is Fundus not visualized?
"Fundus not visualized" means that the back part of the eye, including the retina and optic nerve, cannot be seen during an examination. This could be due to factors like cataracts, vitreous opacities, or poor dilation of the pupils. Further evaluation may be needed to fully assess the health of the eye.

Which one does not belong in the grouping choroid sclera vitreous humor or retina?
Sclera does not belong because it is the tough, white outer layer of the eye, while choroid, vitreous humor, and retina are internal structures within the eye that play different roles in vision.
What structures protect and cover the eye?
eyelids and eyelashes
Which accessory eye structures function to produce the tears that cleanse and protect the eye?
lacrimal gland
