301 Final Flashcards
how many bones are in the head?
22 bones
bones of the cranium
frontal, parietal, occipital, and temporal
bones in the head stay where they are supposed to be because of
sutures
sutures
join the bones of the head together include the coronal, sagittal, and lambdoidal
coronal suture
ear to ear
lambdoidal suture
along the occipital
sagittal suture
front to back
corners of the eye
lateral and medial canthus
sclera
white part of the eye. helps to maintain the size and shape of the eye
cornea
clear covering. allows light rays to enter, responsible for blink reflex, and highly sensitive to touch
iris
eye color and regulates the amount of light that enters the pupil
ciliary body
produces aqueous humor and contains the muscle that controls the shape of the lens
pupil
open and closes to permit light to enter the eye
lens
sits behind the pupil, retracts and focuses light on to the retina
choroids
cover the recessed portion of the eye and are a network of blood vessels to the eye
vitreous humor
clear gel in the posterior segment of eye. maintains intraocular pressure
rods
work in dim light and peripheral vision receptors
cones
bright light and provide sight to color
retina
innermost layer of the eye. covering of the back of the eye. extension of the optic nerve. receives and transmits visual stimuli to the brain
optic disc
where the optic nerve comes into the eye
macula
responsible for central vision. on retina with greatest concentration of cones
anterior chamber
space between the cornea in the front
posterior chamber
starts behind the iris and goes to the lens and filled with aqueous humor that helps nourish the cornea
superior rectus
cranial nerve 3 - elevates the eye upward and adducts and rotates the eye medially
inferior rectus
rotates eye downward and adducts and rotates the eye medially - cranial nerve 3
lateral rectus
moves eye laterally - cranial nerve 6
medial rectus
moves. eye medially - cranial nerve 3
superior oblique
turns the eye downward and abducts and rotates the eye medially - cranial nerve 4
inferior oblique
turns eye upward and abducts and turns the eye laterally - cranial nerve 3
explain the visual pathway
light rays enter the cornea and are refracted on the central fovea which is inverted, reversed, and focused on the retina. It then goes to the brain where the image returns to its original form
cerumen
earwax
middle ear contain
the tympanic membrane, bone Eustachian tube
bones of the ear

what does the inner ear do to sounds?
conducts sound vibrations from external ear to inner ear
eustachian rube helps with
equalizing pressure
explain the sound pathway
sounds hit the tympanic membrane, tympanic membrane vibrate, ossicles vibrate, vibrations travel via fluid of the cochlea, hair cells of organ of corti, cranial nerve 8 (acoustic), sent to temporal lobe of the brain
