Essay --
The five senses include sight, smell, touch, taste, and hearing. Sight is the power of seeing objects and people. To see we use our eyes, our eye is a sphere with a diameter of about 2.5 cm or 1 inch. Our eyes include the eyebrows, eyelids, conjunctiva, lacrimal apparatus, and extrinsic eye muscles. The eyelids are thin, skin covered folds supported by the connective tissue sheets called tarsal plates and are separated by the palpebral fissure and meet at medial and lateral angles of the eye. The eyelid muscle cause blinking every 3-7 seconds and when the objects get in your eye, the flexibility is activated to protect the eye. The eyelashes also protect the eye. Anything that touches the eyelashes is blown away because it will cause your eye to blink. The conjunctiva in our eyes is a mucous membrane; it helps to line the eyelids. The function of the conjunctiva is to produce a lubricating mucus that prevents the eyes from drying out. A conjunctival sac is where contact lens lies and occurs when the eyes are closed and a slit like space occurs. An inflammation of the conjunctiva is called conjunctivitis and happens when the eye get red and really irritated. The lacrimal apparatus in our eyes drains the lacrimal secretions into the nasal cavity. The lacrimal fluid in the eye cleans and protects eye as it moistens. The fluid contains mucous, antibodies, and lysosome. The extrinsic eye muscles originate and insert into outer surface of the eyeball. The extrinsic eye muscles allow the eye to follow a moving object and provide wires to maintain shape of eyeball and hold it in orbit. When movements of these muscles are not the same, a person cannot focus on images correctly and see two images instead. The eye is called an eyeball and ha... ...cines. They may also help you cope with it by teaching you how to cooperate with noise around you. When doctors check your ears that may find OME, itââ¬â¢s thin and watery. If fluid is still present after six weeks the treatment may include having more observations and having to take tests. For us to tell what foods and scents delight us, we use our sense of smell. Your sense of smell helps us to determine what we like to have to eat and wear on different types of occasions. Your sense of smell can also be used for other things like smelling nature around you and smelling the different kind of foods there are around the world. Smell has a chemoreceptor that respond to chemicals in an aqueous solution. Smell receptors are excited by the airborne chemicals that dissolve in fluids coating nasal membranes. The organ of smell is a yellow patch of pseudostratified epithelium.
