Question

Smallest bone in the human body is
(1) Stapes
(2) Malleus
(3) Patella
(4) Navicular bone

Answer 1

Hint: There are 206 bones in the adult human skeleton. The skull, spine (vertebrae), ribs, arms, and legs are among them. Bones are made up of connective tissue that is calcium-reinforced, as well as specialised bone cells. Bone marrow, which produces blood cells, is found in almost all bones.

Complete answer:
-Sound waves must enter the auditory canal, pass through the tympanic membrane (eardrum), and then enter the middle ear compartment before being acknowledged by the brain.
-The sound waves then vibrate the malleus, incus, and stapes, which are made up of three bones known as ossicles.
-The smallest bone in the human body is the stapes.
-Because it strikes the anvil-shaped incus, the malleus is frequently compared as a hammer. After that, the vibrations pass through the stapes.
-Because of its horseshoe-like shape, the stapes can be compared to a tuning fork. In Latin, the term means "stirrup."
-Hearing and balance are two primary functions of the ears, which are dependent on specialised sensors known as hair cells.
-Sound waves enter the outer ear, travel through the middle ear, and finally reach the inner ear, which is made up of a complex network of nerves, bones, canals, and cells.

So, the correct answer is option no. 1

Note: The inferior and superior crus, two branches of the stapes, transmit sound vibrations to the flat base of the bone. The vibrations then pass into the inner ear, where they are converted into neuronal data and sent to the brain via the cochlear and auditory nerves.
