1. The Eye and Eyesight: Large Structures
Would you be able to see anything without a lens in your eye? Does the lens change shape? Does the iris? What structure gives you your eye color? Find out all of this and about things like the ciliary muscles and the cornea as we delve into this lesson.
2. Receptors of the Back of the Eye: Retina, Rods, Cones & Fovea
Find out how we see the world in color, what rods and cones are, and how camera film fits into all of this. In addition, you'll find out what the retina is and what gives you the ability to see at night.
3. How Receptors of the Eye Conduct Information via the Optic Nerve
You will learn how your eyes are able to see the image in front of you thanks to special cells called photoreceptors. In addition, these receptors have very important proteins called rhodopsin and photopsin; and all of these things work together to transmit information to your optic nerve.
4. Anatomy of the Ear's External Structures
What is the pinna? Is it the same thing as your earlobe? Does the eardrum have anything to do with the tympanic membrane? Find out as we explore all of this and other important structures involved in the sensation of hearing as sound enters your ear.
5. Cornea: Definition & Function
One of the most important structures in your eye is the cornea. In this lesson, you'll learn what the cornea is and how it helps you to see. You'll also learn about some common disorders of the cornea and how they are treated.
6. What Is the Cochlea? - Definition, Function & Location
Our ear is divided into three main parts, each containing different structures responsible for different roles. This lesson focuses on our cochlea, which is found in our inner ear and is structured so that it is able to carry out its part in allowing us to hear.
7. What Causes Sensitivity to Sound?
Are you really sensitive to noise? Even noise that is completely normal in volume for everyone else? Read on! This lesson is going to name some of the many reasons why someone might have increased sensitivity to sound.
