The basilar membrane of cochlea

[A]: Hair cells on the basilar membrane (the organ of corti) are responsible for hearing. [R]: Pressure waves, which begin at the ovaI window, cause the basilar membrane, to vi- brate so that the cilia of the hair cells touch the tectorial membrane. This causes the hair cells to initiate nerve impulses, which are carried by the auditory nerve to the brain.

Assertion : Hair cells on the basilar membrane (organ of Corti) are responsible for hearing. Reason : Pressure waves, which begin at the oval windows, cause the basilar membrane to vibrate so that the cilia of the hair cells touch the tectorial membrane. This causes the hair cells to initiate nerve impulses, which are carried by the auditory nerve to the brain.

Given below are some of the process which takes place in our ear when we are exposed to any sound. Arrange these in the correct order of sequence. (a)The eardrum vibrates the transmits the sound wave to the ear ossicles. (b) Vibration travel from oval window to the fluid of cochlea. (c) Ripples in the basilar membrane band the hair cell against the tectorial membrane (d) Generation of waves in the lymphs. (e ) sound waves are collected by the pinna. (f) generation of nerve impulse and transmission through auditory nerves to the brain

These questions consist of two statements each,printed as Assertion and Reason.While answering these questions you are required to chose any one of the following four responses. If both Assertion and Reason are true and Reason in correct explanation of Assertion. If both assertion and Reason are true but reason is not correct explanation of Assertion. If Assertion is true but Reason is false. If both Assertion and Reason are false. Assertion:Hair cells on the basilar membrane (organ of Corti) are responsible for hearing. Reason:Pressure waves ,which begin at the oval windows ,cause the basilar membrane to vibrate so that the cilia of the hair cells touch the tectorial membrane .This causes the hair cells to initiate nerve impulses,which are carried by the auditory nerve to the brain.
