In this post we would come through the definitions shortly. 1. Accommodation: - The adjustment of the eye made normally for looking at objects at different distances. To bring an object into focus on the retina, the lens is made thinner or fatter by the ciliary body. 2. Anterior chamber: -  This is the area behind the cornea and in front of the lens and iris.  Aqueous humor is contained in it. 3. Aqueous humor: - Fluid is produced by the ciliary body and found in the chambers which are anterior and posterior. 4. Choroid layer: - The vascular and middle layer of the eye between the retina and the sclera. 5. Ciliary body: - It is the structure which is on each side of the lens that connects the choroids and the iris. This also contains ciliary muscles, which control the shape of the lens, and secretes aqueous humor. 6. Cones: - The receptor cells which is called photosensitive receptor cells transform light energy into a nerve impulse. Cones are responsible for col...

In the recent post you have learned about the rods and cones.An optic nerve is the nerve of which light energy is focued on the retina, a chemical change occurred in the rods and cones initiating nerve impulseswhich travel from the eye to the brain via the optic nerve. The region in the eye where the optic nerve meets the retina is called retina is called the optic disk. This optic disk is otherwise called as the blind spot of the eye. A small oval which is called the macula is yellowish area to the side of the optic disk.  A central depression which is called fovea centralis is also contained in it. which composed of largely of cones, and is the location of sharpest vision in the eye.  If fovea's portion or macula's portion is damaged, central vision blindness occurs and the vision is reduced. Through the opthalmoscope the fundus of th eye is the posterior and the inner part is visualized.  The rods and cones in the retina syn...

The ciliary body secretes a fluid called aqueous humor other than the shape of the lens. This fluid flows through the anterior chamber and posterior chamber of the eye. The fluid remains constant and that is produced and leaves the eye through a canal which carries it into the bloodstream. Vitreous chamber is the other cavity of the eye, which is a major region behind the lens which is filled with soft, jelly-like material. This vitreous humor regulates the shape of the eyeball and is not perfectly formed again. Blindness can be caused due to escape from the eye. To further refract light rays, both these humors (aqueous and vitreous) function. The thin, delicate and sensitive nerve layer of the eye is retina. This retina is a layered structure with many layers of neurons interconnected by the synapses. Light energy, which is in the form of waves travels through the eye, it is refracted by the cornea, lens and fluids. Cone-rod dystrophy explains a number of diseases where the loss...

Light rays pass through the dark center of the eye, called the pupil. The mucous membrane which is called the conjunctiva that lines the eyelids and coats the front portion of the eyeball over the white of the eye. The conjunctiva is very blur and colorless except when blood vessels are dilated. Dust or smoke may cause to dilate the blood vessels and give the conjunctiva an appearance of red which is generally known as bloodshot eyes. The cornea which is a fibrous, transparent tissue that extends over the pupil and colored eye portion. The cornea works as it bend, or refract, the rays of light; so that they are indented properly on the cells of the sensitive receptor in the region of the eye which is posterior. The cornea is a vascular which has no blood vessels but receives its nourishment from blood vessels near its junction with the white of the eye, the selera. For people with scarred or opaque corneas are successful corneal transplants because the cornea has no supply of blo...

In the recent chapters we have learned about the sense organs; the eye and the ear. Now in this chapter we would learn about in brief and recall the points.The sensitive nerve endings in the corium layer of the skin receive impulses from stimuli of various kinds and applied to the external surfaces of the body. These nerve endings transmit electrical messages, initiated by the stimuli, to regions of the brain (cerebrum and thalamus) so that we can able to identify sensations through temperature, touch, pain, and pressure. The nerve cells which carry impulses from a sense organ or sensory receptor area, such as the skin, tastebuds, and olfactory regions which are also called centers of smell in the nose, to the brain are called afferent sensory neurons. We already came across through the eye and the ear which are the sensory organs, like the skin, taste buds, and olfactory regions. Because these are receptors, whose sensitive cells may be activated by certain form of enrgy or stimul...
