Question

Between malleus and incus, the joint found is
A) Incubo Malleolar Joint
B) Gliding joint
C) Pivot joint
D)None of the above

Answer 1

Hint: Ears are the sensory organs that detect and receive the sound waves and convert them into the nerve impulses, hence help in hearing. However, hearing is not the sole function of the ears. The ears also maintain the body balance or body equilibrium. So, the ears perform two sensory functions: Hearing, and Maintenance of body balance.

Complete answer:
Structure of human ear:-Anatomically, the ear can be divided into three major sections
The middle ear contains three delicate bones, called the ear ossicles. The three ear ossicles are the malleus, incus and stapes. These are their Latin names, which have simple descriptive English equivalents. The malleus bone is hammer-shaped. Out of the three ear ossicles, malleus is the outer one. The handle of malleus is attached to the inner side of the tympanic membrane. Incus bone lies in the middle of three ear ossicles and is attached to malleus on the outer side and to stapes on the inner side. The incus bone is anvil-shaped (anvil is an instrument, commonly used by cobblers). The third in line of this chain of bones is the stapes which is stirrup shaped.
   Now let us find solution from given options
A) Incudomalleolar Joint : It is a kind of synovial joint that is present between malleus and incus. This helps to transfer vibrations between the middle ear.
B) Gliding joint : It is present between the surface of two flat bones at the point of articulation and is a kind of synovial joint.
C) Pivot joint : It is also called a rotatory joint and is present in the knee.
D) None of the above : As one of the options is correct , this cannot be correct. is Incudomalleolar Joint

Hence the correct answer is option ‘A’ i.e, Incudomalleolar Joint.

Note:Ear is Act as the sensory organ of the Body, along with eye ear, contain the hearing receptor which helps a person to hear the thing, it changes the vibrations that occur in the environment and reach to the brain.
