What are extrinsic (6) that move the eyeball and intrinsic (iris and ciliary body)
Inflammation of the membranes that line the eyelids and cover the eyeball
What is conjunctivitis (caused by irritant or pathogen)
This is the nerve supply for Olfaction
What is CN I (the olfactory nerve)
These divisions make up the ear
What are the external ear, middle ear, and internal ear
What is the external ear
What are Vision, hearing, equilibrium, taste, and smell
This is how the eye is protected
This cleans and lubricates the eye via a mechanism
What is the lacrimal apparatus
This outermost layer [BLANK] of the eyeball is composed of white fibrous tissue that is modified into this delicate structure [BLANK]
What is the sclera and cornea
This is the colored part of the eye that regulates the mount of light that can enter, containing the pupil
What is the iris
Trachoma is a caused by this agen
What is Chlamydia trachomatis
These are the nerve supplies for gustation
What is the facial nerve (CN VII) and glossopharyngeal nerve (CN IX)
The external auditory canal conducts this role with these contents
What is opens from outer ear and extends to the tympanic membrane (lined with fine hair, sebaceous glands, and ceruminous glands to lubricate and protect)
What are the ossicles and eustachian/auditory tube
What is olfaction
What is 90%
This is the role of tears
What are to clean, moisten, lubricate, and nourish the cornea and anterior sclera; also contains bactericidal enzyme
This is considered the window of the eye
What is the cornea (clear and transparent without any blood vessels)
The role of the Ciliary Body
What is to change the shape of lenses during accommodation to focus near or far
This is a newborn eye infection that is contaminated through the birth canal if the mother has this infection.
What is Ophthalmia neonatorum and gonococcal infection
These nerves are utilized by the eye
What are nerves II, III, IV, V, VI
*****TRIPLE POINTS*****
Tell me each individual role
This is the role of the tympanic membrane
What is a fibrous partition (ear drum) that vibrates to respond to sound waves and transmitted to bones of the ear
These are found in the internal ear
What are the vestibule, cochlea, semicircular canals, and perilymph
This is another term for sense of taste
What is gustation
These are the protective structures of the eye
What are the eyelids, orbital cavity, eyelashes, lacrimal apparatus, and conjunctiva
This is a reflex of that spreads tears across the eyes and is normally done 6-30 times/minute
What is blinking
****EXTRA 100 POINTS FOR EACH ANSWER*****
What can cause our reflex to blink?
The choroid is the middle layer of the eyeball that is vascular but also plays this role
What is (blood vessels nourish surrounding tissue) contains dark brown/black pigment to absorb excess light and keep the eye dark inside to prevent reflection
This is the difference between aqueous humor and vitreous humor
What is
Aqueous-clear watery fluid that occupies and circulates through the anterior and posterior of the cornea and gives curve like look.
Vitreous-jelly-like fluid that fills the posterior cavity of the eye (after lens), maintaining the spherical shape
What is color blindness, affecting the cones.
This is inflammation of the middle ear due to bacteria or virus
What is otitis media
These are the three ossicles that extend from the tympanum to the oval window/vestibule
What are Malleous/hammer, Incus/anvil, and Stapes/stirrup
This the main role of the semicircular canals
What is to control a sense of balance
What is the epithelium of the nasal cavity
The orbital cavity is composed of these bones
What (is the bony, cone-shaped socket lined with fatty tissue to protect the eyeball) are the frontal, sphenoid, ethmoid, maxilla, zygomatic, and lacrimal
This is the conjunctiva
What is a think transparent layer of mucous membrane that covers the exposed eyeball and lines the inside of the eyelids
This inner layer of the eyeball contains two specialized nerve cells that are sensitive to light
What is the retina, contains rods and cones
This is the role of the Crystalline Lens
What is separates the anterior from posterior, containing of jelly-like material that accommodates by flexibility
*******DOUBLE POINTS******
What happens/what do we treat with a more convex vs concave look?
This occurs with astigmatism
********DOUBLE POINTS*******
How do you treat this?
This nerve works with the ears
What is the vestibulocochlear nerve (CN VIII), carries impulses for equilibrium for the vestibule and semicircular canals
These are the main functions of hearing
What is to hear and maintain equilibrium
*******DOUBLE POINTS********
What does each division of the ear focus on?
Spiral tube shaped like a snail shell that contains the organ corti to help translate sound vibrations into nerve impulses
What is the cochlea
What are sweet, sour, salty, and bitter.
*******DOUBLE POINTS********
Where are they located?
The lacrimal apparatus contains these structures in the eye
What are lacrimal gland, lacrimal ducts, lacrimal sacs, nasolacrimal duct, and tears (along with blinking)
Cones are...
What are less sensitive to light, ability to see bright light, sensitive to red/green/blue, details to fine movement
What are very sensitive to light, ability to see in dim light, dark adaption, B/W, gross movement/shapes, Vit A needed for proper functioning of the rods (lack =night blindness)
They eye completes refraction by this activity
What is bends the light of rays from one medium to another density and allows light to be focused on the retina where cones and rods are located
This is the difference in Glaucoma and Cataracts
What is
Glaucoma-increased fluid pressure of the eye, aqueous humor imbalance
Cataracts-opacification of the lens (trauma, old age, loss of sight, disease)
The vestibulocochlear nerve carries impulses for hearing, also referred to as...
What is the acoustic/auditory nerve
This is found in the internal ear that can cause feeling of dizziness and vertigo (stimulates the semicircular canals)
What is the perilymph
This is the role of the vestibule in the internal ear
What is the oval cavity located in the center of the inner ear next to the oval window that contains receptors for equilibrium to control balance
