Major Structures of Eye
Pupil: Opening that lets light in eye
Iris: Circular muscle
Cornea: Transparent covering
Lens: Focus light rays onto fovea
Choroid: Dark pigment layer
Ciliary Body: Controls shape of lens
Sclera: White part of eye
Retina: Layer of sensory receptor cells
Vitreous Humor: Jelly like fluid maintains shape
Fovea: Small depression with high concentration
Aqueous Humor: Water like fluid behind cornea
Diseases with the eye
Glaucoma: Aqueous humor drainage blocked
Astigmatism: Unequal curvatures in parts of cornea
Cataracts: Clouding of the lens
Hyperopia: Parallel light rays focused behind retina (farsightedness)
Color Blindness: Inability to perceive color because of defective cones
Myopia: focused in front of retina (nearsightedness)
Conjunctivitis: Inflammation of the conjunctiva by bacterial infection
Functions of the Endocrine System
Communicates with cells to produce hormones
Cells enter tissue into an organ and secretes hormones
Only affects Target Cells
Works with nervous system for homeostasis
Regulate number of metabolic process
Hormones diffuse into bloodstream
Major Glands and Organs
Pituitary
Parathyrioid Glands
Hypothalamus
Thyroid Gland
Pineal Gland
Adrenal Glands
Pancreas
Ovaries
Testes
Liver
Hormones
Insulin: Lowers blood sugar
Glucagon: increases blood sugar
Parathyroid Hormone: calcium/ion Homeostasis
Testosterone: causes growth and increase in bone strength
Estrogen: Develops fetus
Melatonin: released usually when dark causes drowsiness
Growth Hormone: stimulates growth
Oxytocin: Uterine contraction and milk production
Disease Associated with Endocrine System
Graves Disease: Automune disorder
Goiter: Swelling of the thyroid
Hyperthyroidism: Caused by genetic causes or a tumor causes weight loss
