The stereo cilia are projected from which part of the hair cell ?

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.

Stereo cilia are present in

Hair like structures protruding from the apical part of each hair cell is known as

From which point of root, root hairs develop?

The metallic cap projecting out from the top of a cell is

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.

[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

Root hair or extension of which type of cell ?

[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.
