.7.☞ retina or scene (Ratina) is the innermost layer tissue composed by neurons and cells, which quickly ต่อแสง cohesion. The inner space of the eyeball the rear of the blades and the stick to the eye has been liquid style similar jelly called.Mer (vitreous humor) packing. Help is made to eyeball's shape is
.8.The retina is made acting as a projection because there is light 2 cell types are Vesta (rod cell), which ไวต่อกา version lighting, but can not separate significantly different. Different colors. The cell, one type is the cone cells (cone cell) which is the cell.
.9. Cone Vesta.
10.☞ pupil, the pupil (Iris) is a muscle contractile and colors according to ethnicity. People have the eyes brown, dark look superficially like black, so called the pupil, the middle eye hole curtain wind called pores, iris (Pupil).The light is made to pass through the hole
.11.☞ lens (Lens) behind the aperture pupil characteristics, clear sheet glass similar convex plain, with ligament, darling (Ciliary muscle). Based on the cornea and between muscles and muscle taken by this round the edge of the cornea.The lens to bend out when it comes to
.12.Vision is vision. Because the light interacting with objects and reflected into the eye eye us through the cornea, lens, the pupils. Into the retina. เซลล์รับภาพ screen. I'll get the picture in the head back and sent to the nerve to the brain.The brain is made functional translation head image is set as head of what you see!13. Disorders of the eye 1.Myopia is to see only the things around. What is far to see no obvious causes, caused by eyeball is longer than usual. Is made to the distance between the lens and the retina, is far too is made to a picture of what looked down.Resolved, that is made with the glasses lens for refracting a let down!14.2.Presbyopia is to see only what is far away. What is close to see no obvious causes, caused by eyeball are short than usual or surface of the lens curve. Noon too little is made to an image of what looked to fall the retina, is made to see.Resolved, that is made with a convex glasses, to help the refraction of light, exit at
.15.3. Astigmatism is to see the real shape distorted from some people to see images in vertical clear, but looking at pictures in a horizontal plane can't see clearly. Look at the clock, such as numbers, see 3 9 obvious but, seeing the number 612 not clear, cause, mainly caused by the curvature of convex lens not eat always screen, eyes and picture ได้ไม่ชัดเจน times every
16.4.Squint strabismus strabismus, squint-eyed., and means a squint squint-eyed pupil two sides are ในตำา position do not match. If more called strabismus And if his eyes are so called cross-eyed, which will see the same image is 2 images because the images fromDon't close the cause is mainly caused by some muscle bundle used goggle soft grip are or are เสียกำาล muscle bundle opposite still work normally. To retrieve the orb to tilt to the brain cannot force the pupil is made to look to the requirements.Correction should consult the ophthalmologist in became a doctor may cure by using glasses
.17.Rhodopsin (retinal opsin) is a pigment to see (visual pigment) of rods
18.While we were reading, we will look at the front of it than the next, such phenomenon. The text is straight. The page so the apparent.Called the fovea (fovea), which is the area with the cone. Density than other areas. The other area of the retina, but
.19. That we see objects of different colors, as a result of the work of conical (cone cell), which are the cells with sensitivity to wavelength of light. Different share is 3 type is 1.Cone cells sensitive to red light (erythrolabe) absorb light in the wavelength red light (565 nm) 2. รูปกร cells with sensitivity to light water to make money. (cyanolabe) absorb light in the
20.The human brain can distinguish various more than 3 color due to the stimulant. Each type of cone, together with the light intensity difference. The mixing of light, as if discoloration.At the same time, it will definitely get to see objects is yellow if stimulate cone that is sensitive to the water แสงสีแดงกับสี money
.21. Ears (Ear): hearing and balance
22 components of ears, the ears of people on each side divided into 3 I 1. Outer ear consists of 1.1 ear. A cartilage covered with thin skin, duty and sound trap is made into the ear 1.2 ears are slightly crooked pipe wall of hole depth of about 2.5 cm ear lining with membrane and under soft tissue filled with the water it is made acting drive fat. Sticky and liquid to nourish the auditory canal, solve
