Given is the diagrammatic representation of the sectional view of cochlea. Select the correct option regarding it.
- A - Organ of corti-responsible for maintenance of balance of the body and posture
- B - Scala vestibuli-filled with perilymph that ends at the oval window
- C - Scala tympani - terminates at the round window which opens to the middle ear
- D - Basilar membrane - nerve impulses are generated against it
The Correct Option is C
Approach Solution - 1
Answer (c) C - Scala tympani - terminates at the round window which opens to the middle ear
Approach Solution -2
A. stands in for the Corti Organ. It is the hearing receptor organ. It has a specialized sensory epithelium that aids in turning the vibrations of sound into brain messages.
B. is an example of Scala vestibuli. It is a vestibular duct, a perilymph-filled chamber located in the middle ear's cochlea. The cochlea receives vibrations via it.
C. is a scala tympani representative. Additionally, the inner ear's chamber is filled with perilymph. It starts at the circular window and goes all the way to the vestibular duct.
The basilar membrane is represented by D. It may be found near the corti organ's base. It has primary hearing sensory receptors. It moves in reaction to sound waves, which causes the hair cells in the organ of corti to depolarize.

Sense Organs
The nervous system must receive, accept, and processes information about the world outside in order to react, communicate, and keep the body safe and healthy. Much of this information comes by way of the sensory organs: the eyes, nose, ears, tongue, and skin. Specialized cells and tissues within these organs obtain raw stimuli and translate them into signals the nervous system can use. Nerves communicate the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception).
- In order to process, the eyes translate light into image signals for the brain.
- The ear uses bones and fluid to convert sound waves into sound signals.
- Exclusive receptors in the skin send touch signals to the brain.
- Chemicals present in the air stimulate signals the brain interprets as smells.
- The tongue is the chief organ of gustation.
