Identify the correct sequence of organs/ regions in the organization of human ear as an auditory mechanoreceptor organ 1. Pinna - Auditory canal - Tympanic membrane - Malleus - incus - Stapes - cochlea - Auditory nerve 2. Pinna- Malleus- incus- stapes- auditory canal- tympanic membrane 3. Pinna - cochlea - Tympanic membrane - Auditory canal - Malleus - Stapes - Incus - Auditory nerve 4. Pinna - Tympanic membrane - Auditory canal - Incus - malleus - Stapes - Cochlea - Auditory nerve

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.

Following is a list of the events (in a random order) that lead to the formation of an auditory impulse. (i)Vibration is transferred from the malleus to the incus to the stapes. (ii)Basilar membrane moves up and down. (iii)Nerve impulse is transmitted in cochlear nerve to auditory cortex of brain for impulse analysis and recognitions. (iv)Sound waves pass through ear canal. (v)Stereocilia of hair cells of organ of Corti rub against tectorical membrane. (vi)Sound waves cause ear drum to vibrate. (vii)Nerve impulse is generated (viii)Vibrations move from fluid of vestibular canal to the fluid of tympanic canal. (ix)Membrane at oval window vibrates. Which of the following options represents these events in a correct order ?
