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.

EYE STRUCTURE AND FUNCTION Eye is like a camera. The external object is seen like the camera takes the picture of any object. Light enters the eye through a small hole called the pupil and is focused on the retina, which is like a camera film.Eye also has a focusing lens, which focuses images from different distances on the retina. The colored ring of the eye, the iris, controls the amount of light entering the eye.It closes when light is bright and opens when light is dim. A tough white sheet called sclera covers the outside of the eye. Front of this sheet (sclera) is transparent in order to allow the light to enter the eye, the cornea.Ciliary muscles in ciliary body control the focusing of lens automatically. Choroid forms the vascular layer of the eye supplying nutrition to the eye structures.ight enters the eye through a small hole called the pupil and is focused on the retina, which is like a camera film.
