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.
Rating Newest Oldest. Best Answer: It's part of the nervous system as it is literally an outgrowth of the frontal cortex of the brain. 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.

1 the retina The retina is the inner layer of the eye. 2  It contains the light receptors, the rods and cones (and thus serves as the film of the eye). 3  The retina also has many interneurons that process the signals arising in the rods and cones before passing them back to the brain. This not only reduces the amount of light entering the eye but also improves its image-forming ability (as does stopping down the iris diaphragm of a camera). 2  the retina The retina is the inner layer of the eye. 3  It contains the light receptors, the rods and cones (and thus serves as the film of the eye).
