In the organ or corti, above the rows of the hair cells is a thin elastic membrane called

Anatomically, the ear can be divided into three major sections called the outer ear, the middle ear and the inner ear. How many statements are correct for inner ear? i. The organ of Corti is a structure located on the basilar membrane which contains hair cells that act as auditory receptors. ii. A large number of processes called stereo cilia are projected from the apical part of each hair cells iii. Above the rows of the hair cells is a thin elastic membrane called tectorial membrane iv. The vestibular apparatus is composed of three semi-circular canals and the otolith organ consisting of the saccule and utricle. v. Semi-circular canals contain a projecting ridge called macula vi. The saccule and utricle contain a projecting ridge called cristae vii. The cristae and macula responsible for maintenance of balance of the body and posture.

The animal cell is surrounded by a membrane called

Stereocilia of sensory cells of human ear come ine contact with elastic membrane called

Stereocilia of sensory cells of human ear come ine contact with elastic membrane called

Cell membrane is also called-

Cornea is covered by a thin membrane called ……………….. .

[A] : Hair cells on the basiiar membrane are responsible for hearing. [R]: Pressure waves which begin at the oval window, cause the basilar membrane to vibrate so that the cilia of the hair cells touch the tectorial membrane. This causes hair cells to initiate nerve impulses

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.
