The correct Answer is:
To identify the correct sequence of organs/regions in the organization of the human ear as an auditory mechanoreceptor organ, we can break down the process step by step: ### Step-by-Step Solution: 1. **Pinna**: The outer part of the ear that collects sound waves from the environment. It is the first structure that sound waves encounter. 2. **Auditory Canal**: After the sound waves are collected by the pinna, they travel through the external auditory canal. This canal directs the sound waves toward the tympanic membrane. 3. **Tympanic Membrane**: Also known as the eardrum, this membrane vibrates in response to the sound waves that reach it. This is the third structure in the sequence. 4. **Ear Ossicles (Malleus, Incus, Stapes)**: The vibrations from the tympanic membrane are transmitted to the three small bones in the middle ear known as the ossicles. The sequence is: - Malleus (hammer) - Incus (anvil) - Stapes (stirrup) 5. **Cochlea**: The vibrations from the stapes are then transmitted to the cochlea, which is a spiral-shaped organ in the inner ear. The cochlea converts these vibrations into nerve impulses. 6. **Auditory Nerve**: Finally, the nerve impulses generated in the cochlea are sent to the brain via the auditory nerve, allowing us to perceive sound. ### Correct Sequence: The correct sequence of organs/regions in the organization of the human ear is: **Pinna → Auditory Canal → Tympanic Membrane → Malleus → Incus → Stapes → Cochlea → Auditory Nerve** This sequence corresponds to option (c): **Pinna → Auditory canal → Tympanic membrane → Malleus → Incus → Stapes → Cochlea → Auditory nerve**.

Arrange the following in the order of reception and transmission of sound wave from the ear drum.Cochlear nerve, external auditory canal, ear drum, stapes, incus, malleus, cochlea.

Rewrite in a correct logical sequence : Oval window. Tympanum, Cochlea, Auditory canal, Ear ossicles (path through which a vibration of sound is transferred in the human ear).

Assertion:The inner ear contains three ossicles (malleus, incus and stapes) which are attached to one another in a chain-like fashion. Reason:The stapes is attached to the tympanic membrane and the malleus is attached to the oval window of the cochlea.

Which of the following are the components of membranous labyrinth of human? --- (a)3-semicircular canals (b)Tympanum (c)Macula (d)Utricule and saccule (e)Organ of Corti (f)Cochlea (g)Ear ossicles

Read the following statements and find out the incorrect statements. a. Anatomically, the ear can be divided into three major sections called the outer ear, the middle ear and the inner ear. b. The outer ear consists of the pinna and external auditory meatus (canal). c. The tympanic membrane (ear drum ) is composed of connective tissue covered with mucus membrane outside and with skin inside. d. The ear ossicles reduces the efficiency of transmission of sound waves to the inner ear. e. The pinna collects the vibrations in the air which produce sound.

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

[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.
