In the ear, the basilar membrane and hair cells are found in the
A-Auditory nerve
B-Anvil and stirrup
C-Cochlea
D-Oval window
C-Cochlea
The correct answer is C - Cochlea.
In the ear, the basilar membrane and hair cells are found in the cochlea. The cochlea is a spiral-shaped structure located in the inner ear and is responsible for converting sound waves into electrical signals that can be interpreted by the brain. The basilar membrane is a thin, flexible layer that runs along the length of the cochlea and supports the hair cells. The hair cells are sensory cells that detect vibrations caused by sound waves and convert them into electrical signals, which are then transmitted to the auditory nerve for further processing in the brain.
The correct answer is C- Cochlea.
To arrive at this answer, one should have a basic understanding of the anatomy of the human ear. The ear is divided into three main parts: the outer ear, middle ear, and inner ear.
The outer ear consists of the pinna (visible part of the ear) and the ear canal. Its function is to collect sound waves and direct them towards the middle ear.
The middle ear is made up of the eardrum (tympanic membrane) and three tiny bones called the ossicles: the malleus (hammer), incus (anvil), and stapes (stirrup). The ossicles transmit the vibrations from the eardrum to the inner ear.
Moving on to the inner ear, this is where the basilar membrane and hair cells are found. The inner ear consists of the cochlea and the vestibular system. The cochlea is the spiral-shaped structure responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
The basilar membrane is a thin strip of tissue within the cochlea that plays a crucial role in hearing. It is lined with thousands of hair cells that are responsible for detecting different frequencies of sound. When sound vibrations reach the cochlea, they cause the basilar membrane to vibrate, which in turn stimulates the hair cells. These hair cells then convert the mechanical vibrations into electrical signals that are transmitted to the brain via the auditory nerve.
Therefore, the correct answer is C- Cochlea.
