Understanding Diabetes
Defines both type 1 and type 2 diabetes. Lists symptoms of both types of the disease. Describes insulin and illustrates its role in the body and shows the steps in glucose metabolism. Briefly describes hyperglycemia and hypoglycemia. Discusses long-term health problems and healthy lifestyle changes.

FYI ~ Healthy food habits thought to avoid diabetes (type 2) choose foods that digest slowly releasing blood sugars into system steadily - get one serving per day of greens (spinach, arugula, roaine, kale) per day; keeping overall fat intake to under 30% of total daily calories; eat nuts high in alpha-linolenic acid (ALA) - walnuts, flaxseeds, almonds, – to improve insulin sensitivity. Also “divide” your plate - half should be produce, a quarter for protein and a quarter for high-fiber starches.

Hearing Loss
Sound vibrations travel through the outer ear canal to the eardrum, then through the bones of the middle ear to the cochlea. Deep in the inner ear, the spinal-shaped cochlea turns vibrations into nerve impulses which are sent to the brain for interpretation as sound. The conversion of physical vibrations to electrical impulses is accomplished in the cochlea by two sets of hair cells along the organ of Corti.
Damage to the hair cells and cochlea is the most common cause of hearing loss. This damage is usually caused by genetic factors, or by overexposure to sound. Excessive sound exposure damages hearing by over stimulating the tiny hair cells. When these cells are damaged, they no longer transmit sound impulses to the brain. The best way to avoid this kind of damage is to wear adequate hearing protection when exposed to loud noises.
Sound intensity is measured in decibels (dB). A normal conversation measures 50-60 dB, while a lawn mower enging is 90 dB. Sterio headphones can range from 105 to 110 dB. the loudest sounds that can be tolerated by the human ear are around 120 to 130 dB.

Eye Disorders
The eyeball has an internal pressure, which keeps the eye spherically shaped. This pressure is produced and maintained by intraocular bluid, which nourishes the lens, iris, and cornea.
The eye constantly replenishes this fluid. Excess fluid is automatically drained from within the ye by ducts located near the iris.
Glaucoma is an eye condition characterized by loss of vision due to damage of the optic nerve. It is usually caused when the jellylike fluid inside the eye is produced faster that it drains away, causing excessive pressure. This pressure can compress the optic nerve or interrupt blood flow to the nerve. In either case theresult is nerve damage, shich causes loss of vision. Glaucoma is one of the leading causes of blindness.
Since most types of glaucoma do not cause pain or readness of the eye, it can be difficult to diagnose. Glaucoma causes loss of peripheral, or side, vision firs. Central vision is only affected when the disease has progressed significantly.
Cataract is the clouding of the lens in the middle of the eye, which prevents light rays from passing into the retina. The image received by the retina becomes dull and fuzzy. This condition can cause partial or complete blindness, but is much more readily treated than glaucoma.

Nearsightedness & Farsightedness
Poster Text: Three components determine the eye's ability to focus. the cornea and lens are responsible for most of the focusing. The third factor is the length of the eyeball. Although this is the least significant element of the eye's focusing behavior, it can cause farsightedness and nearsightedness.
Farsightedness (Hyperopia) - If you are farsighted, it means you have difficulty seeing things that are close. This is caused by a cornea that doesn't have enough curve, or an eyeball that is too short.
In an eye that is too short, light entering through the cornea and lens at the front of the eye comes into focus behind the retina at the back of the eye. This results in blurry images.
Normal Sight - In a normal eye light passes through the cornea and lens at the front of the eye, and is delivered perfectly to the retina. If the cornea is curved properly and the eyeball is the right length, then the object being seen is aligned directly on the retina.
Nearsightedness (Myopia) - If you are nearsighted, it means you have difficulty seeing things that are far away.
Nearsightedness is usually caused by an eyeball that is too long or a cornea that is too curved, causing images to be focused short of the retina in the back of the eye. When the focal point is in front of the retina, images at a distance appear blurry by the time they reach the retina.
