Which lists the structures, in correct order, through which light passes when it enters the eye?
O cones, pupil, lens, sclera
O sclera, iris, pupil, lens
O vitreous humor, lens, pupil, cornea
O cornea, pupil, lens, vitreous humor

Answers

Answer:

The correct order in which light passes through the structures of the eye is cornea → pupil → lens → vitreous humor

Explanation:

Light and images are the stimuli that must be perceived by the eye for the sense of vision to be produced. These stimuli must go through some ocular structures before reaching the retinal photoreceptors, passing to the optic nerve and being conducted to the brain.

The order of ocular structures that light passes through before reaching the retina is

Cornea, the outermost layer of the eye that covers the iris.Pupil, which corresponds to the opening in the iris that regulates the passage of light.Lens, which is the transparent structure that is found in the anterior chamber of the eye and allows focusing.The vitreous humor is a substance with gel consistency that is behind the lens and separates it from the retina.

The correct ocular function, with respect to vision, depends on the integrity of all structures through which light must pass before reaching the retina.

The correct order through which light passes when it enters the eye is

sclera, iris, pupil and then the lens

The eye is the sense organ for sight. It uses light from objects to create

images which is processed by the brain.

The light first passes through the outer layer known as the sclera which

contains the cornea, then through the iris, pupil, lens and the vitreous

humor. This is the space between the lens and the retina and finally on to the retina.

ANSWER: FALSE

Answers

The statement "There aren't health risks with any yoga positions or forms" is false.

What is yoga?

All yoga techniques may help you balance your body, mind, and soul, but they do it in different ways. Some yoga styles are aggressive and intense. Others are calming and meditative in nature.

Yoga, regardless of the form, is an excellent method to stretch and strengthen your body, focus your mind, and soothe your spirit. There are health risks with yoga poses when it is not done correctly, and these poses can cause muscle displacement or pain.

Even when done correctly, some stretching exercises might be dangerous. Legs that get stiff or sore after a run are not always indicative of a running injury, but may indicate that your body is responding to the new physical load.

Therefore, the statement is false.
