part 3 of test 7


glands embedded on the back surface of the thyroid gland that regulates calcium Parathyroid glands
two-section gland behind the sternum breast bone that we recall has a lymphatic-immune association, contains disease fighting white blood cell lymphocytes thymus gland
hormone stimulates development and output of the body's most powerful white blood cell lymphocytes called T-cells Thymosin
two 2x2 pyramid-shaped glands, one one each that sits atop each kidney that have two distinctively different parts, tissuses and functions: Adrenal gland
outer part is yellow colored and secretes two hormones 1. aldosterone 2. cotisol cortex
regulates fluid, salt, and electrolyte mineral levels Aldosterone
regulates blood sugar (glucose) levels known as stress hormone Cortisol
inner part secretes two hormone that deal with fight or flight challenging, threatening, stressful, emergency situations. ignite alarm reaction reflex medulla
released immediately into the bloodstream to trigger extra liver-stocked glycogen-sugar to be released for added strength epinerphrine
last longer in emergency situations in case the emergency requires hours instead of minutes norepinephrine
millions of small clusters of cells throughout the inner pancreas that function to control blood sugar, and secrete two opposite hormone island of langerhans
released when we eat, particularly carbohydrates, and when these carbs enter it carries it onto cells for energy or storage use insulin
released when we havent eaten. tells the liver we need nourishment glucagon
clear transparent protective window membrane over the exposed part of the eyeball that is lubricated by tears conjunctiva
clear outer covering thats unique in that it has NO blood vessels cornea
white globe part round shape of eyeball. six muscles attach to this sclera
curved, adjustable structure similar to a magnifying glass that allows for fine focusing of both near and far objects. lens
change its curve-ability shape, which automatically responds to the proximity/distance of an object, creating a sharper image, and thus, accommodates ciliary muscles
when lens are uneven, and thus unequal focusing astigmatism
when the lens are cloudy cataract
hole in the center of the eye. it controls light brightness by widening in dim light and closing in bright pupil
thin, multi-layered tissue about the size of a fingernail that covers 75% of the back of the eye and serves as the screen retina
discern color because they contain the three basic spectrum pigments with wide variations cones
that only see black and white, because they have only one light-sensitive pigment, and therefore cannot discern color; however, this is not all bad because we can see in the dark for night vision rods
inherited condition of absent retina cones color blindness
when one of the many retina layers becomes seperated detached retina
eye-ball is either too short or too long, and images fall either short, of or too far beyond, the retina screen far or near sigtedness
images leave the retina from the back of the eyeball and travel to the brain, which then gets images right side up and puts everything into meaningful patterns/images optic nerve
tears contain anti-bacteria agent called this Lysozyme
constantly lubricate and clean the eyes basal
wash away irritants and foreign matter reflex
crying tears when hormones are present emotional
tears are carried to the eye surface by 12 tiny ducts that lie under the eyelids lacrimal ducts
tears drain here Nasolarcrimal duct
eyeball is filler with this completely clear gel fluid that functions to maintain eyeball shape, inflation, pressure, and to keep retina screen in place Aqueous Humor
pressure could build with the eyeball and begin to "kill" all of the retina's rod and cone photo-receptors as well as cutting off blood supply to the optic nerve glaucoma
thinnest skin of the body, but muscle-structure capable of a very quick blink reflex eyelids
protect eyes against environmental items such as pollen and can also sense when something is coming toward the eye, giving us a micro-second to react eyelashes
