SPECIAL SENSES: Vision/Eye with diagrams

How Your Eyes Work: Diagram of the Back of Your Eye

The anatomy of the posterior eye diagram showcases the complex visual system that enables sight through specialized structures and cells. The eye's intricate components work together to process light and transmit visual information to the brain.

  • The eye consists of multiple layers including the sclera, cornea, choroid coat, and retina
  • Photoreceptor cells cones and rods are essential for processing different types of light and color vision
  • The lens and cornea work together in focusing light rays onto retina for clear vision
  • Various eye conditions like myopia, hyperopia, and astigmatism occur when light focusing is impaired
  • Special senses include sight, hearing, smell, taste, and balance/equilibrium

Page 2: Special Senses and Eye Layers

This page details the five special senses and the protective structures of the eye. It explains the various layers of the eye and their specific functions in vision.

Definition: Special senses are specialized sensory systems including sight, hearing, smell, taste, and balance/equilibrium.

Example: The lacrimal gland produces tears containing lysozyme, which provides antibacterial protection for the eye.

Highlight: The eye has multiple protective layers, with the sclera providing overall protection and the cornea allowing light transmission.

Page 3: Vision Processing and Photoreceptors

The third page focuses on how the eye processes light and the role of specialized cells in vision. It details the function of the lens, iris, and photoreceptor cells.

Vocabulary: Photoreceptor cells are specialized neurons that convert light waves into electrical signals.

Definition: The ciliary body is a smooth muscle that adjusts the lens shape for focusing on objects at different distances.

Highlight: Rods and cones serve different purposes - rods function in dim light while cones provide color vision.

Page 4: Vision Problems and Corrections

The final page explains common vision problems and their corrections, including modern surgical interventions. It details how images are projected and focused in the eye.

Definition: LASIK LaserAssistedInSituKeratomileusisLaser-Assisted In Situ Keratomileusis is a surgical procedure that reshapes the cornea to correct vision problems.

Example: Myopia occurs when light rays focus too early, resulting in difficulty seeing distant objects.

Highlight: The eye projects an upside-down, reversed image onto the retina, which the brain then corrects for normal vision.

Page 1: Eye Structure and Components

The first page presents a detailed anatomical diagram of the eye, highlighting its key structural components. The posterior eye contains multiple layers and structures that work together for vision processing.

Definition: The posterior eye refers to the back portion of the eye, containing crucial components for vision processing including the retina and optic nerve.

Vocabulary: The vitreous body/humor is the gel-like substance that fills the posterior chamber of the eye.

Highlight: The retina contains the fovea centralis, which is responsible for sharp central vision, along with the central retinal artery and vein.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Brad T

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Aubrey

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
