Nerve that is a tract of CNS, extends from chiasma opticum to bulbus oculi, radiates in retina

External and internal sheath of the optic nerve

Structure beginning the optic nerve visible on the fundus, lacks receptors

Cloudy area in the lens that leads to decrease in vision

Condition in which the eyelid turns outward

Eyelids roll inward

Condition of having dry eyes

Inflammatory or infective condition of cornea involving disruption of its epithelial layer with involvement of the corneal stroma

Disorder of the third eyelid

Sense organ receptive to sounds, gravity and changes in the position of head

Parts of the ear

Structures that external ear consists of

Auricula

Externally visible part of the ear

Canal leading from the base of auricle to the tympanic membrane

Structure that separates the middle ear from the meatus acusticus externus

Funnel - shaped proximal part of the auricle

Cavity of the funnel - shaped proximal part of the auricle

Long hairs protecting the entrance to external acoustic meatus

Concave internal side of the auricle

Free margin of the auricle passing over apex

Elongated prominence on the rostromedial border of the entrance to the auricular cavity

Structures that middle ear comprises

Space between pars petrosa and tympanica of the temporal bone

Space with auditory ossicles that transmit the vibrations of tympanic membrane to the perilymphatic space in the internal ear

Structure closed by the base of the stapes by means of which vibrations act on the perilymph in the internal ear

Round foramen in the medial wall of the tympanic cavity, closed by membrana tympani secundaria

Three articulating bones that transmit the vibrations of tympanic membrane across the tympanic cavity to the perilymph in the Scala vestibuli

Most external auditory ossicle, articulating with the incus manubrium embedded on tympanic membrane

Most internal auditory ossicle, articulating with the incus and closing fenestra vestibuli
