Question

Mention the location of the following:
a) Semicircular canal b) Utriculus c) Cochlea d) Oval window

Answer 1

Structure:

1. The inner ear's semicircular canals are three small, fluid-filled tubes that help with balancing.
2. The utricle is a tiny membranous sac located within the inner ear's vestibule. It plays a crucial role in orientation and static equilibrium, especially when the body is tilted horizontally.
3. The inner ear's cochlea is a snail-shaped structure. Sound vibrations are converted into electrical signals, which travel via the auditory (hearing) nerve.
4. The fenestra ovalis, or oval window, is a connective tissue membrane that runs from the end of the middle ear to the beginning of the inner ear.

Location:

1. The inner ear has semi-circular canals. These help to keep the body's dynamic homeostasis in check.
2. The utriculus is located in the inner ear. It is the tube that links the cochlea to the semicircular canals. Also it helps to keep the body's static equilibrium.
3. The inner ear includes the cochlea. It assists in the passage of auditory nerve impulses to the brain.
4. The oval window is located in the ear's centre. It helps the fluid inside the cochlear canals to vibrate.
