- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Sight, Hearing, and Other Senses chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Sight, Hearing, and Other Senses chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any sight, hearing, or other senses question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students will review:
This chapter helps students review the concepts in a sight, hearing, and other senses unit of a standard middle school life science course. Topics covered include:
- Receptors of the back of the eye
- Anatomy of the ear's outer structures
- Relationship of the inner ear to both hearing and balance
- Structures and functions of the middle ear
- Smell, taste and touch
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. Cochlear Implants: Pros & Cons
Cochlear implants are electronic hearing devices that can help restore some levels of hearing to someone who is deaf. As with any medical procedure, there are benefits and drawbacks to them, so read on to learn more.
6. Semicircular Canals: Function & Definition
In this lesson, we'll explore what the semicircular canals are and how they function to create your body's sense of directional movement and acceleration. When you are through, you can test your understanding with a short quiz.
7. Misophonia: Definition, Causes, & Treatment
This lesson goes over a rare condition known commonly as misophonia. You'll learn its definition, what sounds it might involve, how a person reacts, as well as its causes and treatments.
