Your ears have three parts â the outer ear, the middle ear, and the inner ear â and each has a specific function. To find out more about how your ears detect and interpret sounds, read the KidsHealth.org articles related to hearing, then take the online quiz on ears (KidsHealth.org/en/kids/earquiz.html) to see how much you learned. Next, label a diagram of the ear on the âHereâs How the Ears Hearâ handout, and explain how sound travels. through the ear.

The eye is formed during embryonic development by a combination of head ectoderm and neural tube tissue, the latter forming the retina.Thus, the retina is not a peripheral sensory organ ... but rather it is an outgrowth of the central nervous tissue. Because of this origin, the retina ...he eye is formed during embryonic development by a combination of head ectoderm and neural tube tissue, the latter forming the retina.

Lens: The lens is a clear part of the eye behind the iris that helps to focus light, or an image, on the retina. Macula: The macula is the small, sensitive area of the retina that gives central. vision. It is located in the center of the retina. Optic nerve: The optic nerve is the largest sensory nerve of the eye. It. carries impulses for sight from the retina to the brain. Pupil: The pupil is the opening at the center of the iris. The iris adjusts the size. of the pupil and controls the amount of light that can enter the eye.
