Eye & Endocrine System, Julie Abundis
Major structure of eye
accessory organs
eyebrow
catch sweat or debris from forehead
eyelashes
hairs that protect eye from debris
lacrimal gland
secrete tears
palpebral/eyelids
protect eye
conjunctiva
transparent mucous preventing eyes from drying out
tarsal glands
keep eyelids from sticking together
extrinsic muscles
control movement of eyeball
superior
inferior
lateral
medial
intrinsic muscles
ciliary body
iris
fibrous layer
sclera
protects and shapes eye
cornea
lets light enter
vascular layer
choriod
helps absorb light preventing from scattering and reflection
ciliary body
ciliary muscles
smooth muscle bundles that control lens shape
ciliary process
secrete fluid that fills cavity
ciliary zonule
transmits tension from ciliary muscle to lens
iris
between cornea and lens
inner layer
retina
coverts light energy
internal chambers and fluids
vitreous humor
holds the neural layer of the retina firmly
aqueous humor
clear fluid
scelra venous sinus
channel that encircles cornea
Major functions of eye
vision
light detection
night vision
focus
depth perception
Major functions of endocrine system
produces hormones
negative feedback
body growth
metabolism
sexual development
