QuestionAnswer
watery liquid located in the anterior and posterior chambers of the eye
which auditory ossicle is attached to the eardrum
layer of the retina contains the photoreceptor cells
inflammation of eardrum
conversion of sound waves to mechanical vibrations is the main function of which part of the ear?
this layer of squamous epithelial cells provides for metabolic exchange between the cornea and the aqueous humor
increasing or decreasing the size of the pupil is known as
hearing loss resulting from damage to hair cells or cochlear division of CN VIII
this layer includes the choroid, stroma ciliary body, and the iris
this structure is composed of dense fibrous connective tissue that provides attachment sites for the extrinsic eye muscles
separation of retinal pigmental epithelium and the neural retina is known as _____ _____.
inner layer of retina that contains light sensitive receptors and complex neuronal networks
how many sensory regions of the inner ear?
embryonic origin of the extraocular muscles
contains the nuclei or cell bodies of the ganglion cells
contains the nuclei or cell bodies of horizontal, amacrine, bipolar, and Muller's cells
hearing loss resulting from sound waves being mechanically impeded from reaching the sensory receptors in the internal ear
central circular aperture of the iris
the transparent front part of the eye that covers the iris, pupil, and anterior chamber.
rods and cones are _______ cells.
this gel like substance acts as the shock absorber of the eye and maintains the shape of the eye
this depression in the retina only contains cones
nutrient layer of the eye containing blood vessels
an outer layer of retina that is composed of simple cuboidal melanin containingcell
a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process.
upper wall of scala media
this epithelium functions to secrete aqueous humor, it is a part of the blood aqueous barrier, and it is involved in secretion & anchoring of the zonular fibers
QuestionAnswer
Effect of age on lens’s elasticity and ability to accommodate
pigment associated with rods
type of innervation (sympathetic or parasympathetic) of constrictor/ sphincter pupillae muscle
composed of the basal lamina of Muller's cells
medical term for earwax
a contractile diaphragm that extends over the anterior surface of the lens. Has melanin pigments:
embryonic origin of the sclera
basement membrane of the corneal endothelial cells
oval appendage of the ear that extends from the lateral portion of the head and collects sound waves
this layer includes the outer retinal epithelium, inner neural retina, and epithelium of the ciliary body and iris.
sensory innervation of the corneal epithelium
the stapedius and the tensor tympani are rsponsible for the ______ reflex.
embryonic origin of the vitreous body of the eye
absorption of fluid in the eye occurs within the ___ __ ____.
contains the processes of horizontal, amacrine, bipolar, and Muller's cells that connect to each other
these cells convert mechanical energy into electrical signal
type of innervation (sympathetic or parasympathetic) of dilator pupillae muscle
this muscle dampens the movement of the stapes.
the auditory ossicles connect the tympanic membrane to what structure?
responsible for the production and maintenance of endolymph
pigment associated with cones
lower wall of scala media
the malleus, incus, and stapes are known as
space between the posterior lens and neural retina
embryonic origin of the lens of the eye
contraction of this muscle tenses the tympanic membrane. Inserts onto the malleus.
this fluid of the inner ear is high in Na concentration and low in K concentration
QuestionAnswer
this fluid of the inner ear is high in K concentration and low in Na concentration
space between the cornea and the iris
contains the nuclei or cell bodies of the retinal rods and cones
the utricle and the saccule are located in what portion of the ear?
the space between the posterior surface of the iris and the anterior lens
true or false: the corneal epithelium is regenrative.
which compartment of the ear contains endolymph?
the macula of saccule detects movements in the _____ plane.
embryonic origin of the incus
contains processes of retinal rods and cones and processes of horizontal, amacrine, bipolar, and Muller's cells
the apical boundary of Muller's cells
contraction of the ciliary muscle causes a change in the shape of what structure?
this layer includes the sclera and cornea
contains processes of ganglion cells that lead from the retina to the brain
the macula of utricle detects movements in the _____ plane.
embryonic origin of the malleus
sensory receptor for angular head movements
embryonic origin of the optic nerve

embryonic origin of the external auditory meatus
site where the optic nerve joins the eye
the embryonic origin of the eustachian tube
this membrane lies beneath the corneal epithelium and the corneal stroma
