[PHYSIO] FINAL REVISION Flashcards
Auditory transduction
Transforming auditory information to electrical impulses (AP)
Auditory discrimination
Ability of cortext to discriminate frequency, locality & intensity of sound
Deafness
Loss of hearing power
Unilateral, or bilateral
Complete or incomplete
Conductive or sensorineural
Near response
Process by which eye brings diverging rays from a near object to focus on camera
Myopia
Refractive condition in which parallel rays come to a point IN FRONT of the retina while accomodation is at rest
Hypermetropia
Refractive condition where parallel rays come to a point BEHIND retina
While accomodation is filly relaxed
Presbyopia
Gradual decrease of accommodation with aging
Near point recedes away
Far point is unchanged
Accommodation power, amplitude & ranghe decrease
Astigmatism
Refractive condition of the eye in which parallel rays come into different foci leading to a blurred image
Refractive power is not the same in different meridians
Cornea/lens curvature is irregular
Iris
Continuation of uveal tract
Circular pigmented disc-shaped structure w a hole in the middle called the pupil
It is in front of the lens
