Eye and the Endocrine System
Diseases associated with the eye
Clouding of the lens that causes the world to appear distorted. The lens can be surgically removed and replaced by an
Drainage of aqueous humor is blocked and fluid backs up. Pressure in the eye increases to dangerous levels and
compress the retina and optic nerve causeing loss in peripheral
vision and can lead to blindness.
Unequal curvatures in parts of the cornea or lens.
Parallel light rays from distant objects are
focused behind the retina. Can see distant objects well but close objects appear blurry. Correction requires convex corrective lenses.
Distant objects are focused in front of the retina. Can see close objects well but distant objects appear blurry. Correction requires concave corrective lenses.
Congenital lack of one or more cone type. Inherited as an X-linked condition.
Inflammation of the conjunctiva usually from bacteria or viral infection.
Diseases associated with the endocrine system
Hypersecretion of GH
In children results in.
Hyposecretion of GH
In children results in dwarfism.
Under-active thyroid. Symptoms are: fatigue, weakness, weight gain or difficulty losing weight.Can cause cretinism.
May be genetic or caused by tumor on thyroid.
Autoimmune disorder that causes hyperthyroidism
The thyroid needs iodine to produce T3 and T4. Lack of iodine can lead to goiter.
Beta cells don’t make insulin leading to blood sugar being too high.
Type II Diabetes
Body produces insulin, but the cells do not respond to it.
Too much cortisol in your body for a prolonged period of time. Causes tumor on pituitary, lungs, pancreas, kidney, or adrenal cortex;
Major functions of the endocrine system
Maintain homeostasis in the body.
names of hormones and their target organ and functions of the hormones
Matains vital horrmostatic balance of callcium ions.
Stimulates osteoclasts to dreakdown calcium .
Regulates body motabalism.
Protines and Lipids
Breakes down protine and lipids to produce glucose.
Regulates the conection of mineral ions.
Prevents water loss by increasing up-take.
Increases the flow of blood to the brain and pancries.
Produces sex hormones.
Lowers blood sugar levels.
muscle and liver cells
Raises blood sugar levels.
Stimulates mammary glands.
muscles, bones, sex organs, and hair follices
Controlls growth and development of sex organs in males.
Primary female sex hormone.
Stimulates the adrenal cortex to produce hormones.
Activa in females during ovulation and pregnacy when it matains appropriate conditions in the body.
Stimulating The thyroid gland.
Human sleep cycle
Regulates sleep cycle
Cells throughout the body
Make you grow.
Major structures and
functions of the eye
Whites of the eye that forms outer covering.
Transparent membrane that covers iris and pupil. Focuses light on the retina.
Passes different amounts of light.
Colored part of the eye that controls the size of the
Nutritious fluid between the iris and the cornea.
Produces aqueous humor and controls lens shape.
Bends light rays to the retna.
Full of light receptors.
Transparent jelly-like fluid that fills the eye and refracts light.
Sends messages from the retna to the brain.
Area where optic nerve attaches.
Provides the blood supply to the eye.
Major glands/organs and their functions
Controls the rate the body produces energy.
Serves a vital role in the development of T cells.
Secretes hormones which have important effects on the way energy is stored and food is used.
Releases many hormones which affect growth, sexual development, metabolism and human reproduction.
Excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food, and secretes insulin and glucagon to control blood sugar levels.
Control the level of calcium in the blood.
Produce the female sex hormones that control reproduction and the female gametes that are fertilized to form embryos.
Responsible for the production of sperm cells and the male sex hormone testosterone.
Controls vital bodily functions: hunger, thirst, body temperature, and hormone secretion.
