The organ of Corti resides within the cochlea, a spiral-shaped structure in the inner ear responsible for hearing. This intricate sensory organ is composed of hair cells, supporting cells, the tectorial membrane, and the basilar membrane. The hair cells, the sensory receptors of the organ of Corti, are arranged in rows and are connected to the tectorial membrane, which vibrates in response to sound waves. The basilar membrane, located beneath the hair cells, is a flexible structure that resonates at different frequencies, allowing the organ of Corti to discriminate between sounds of various pitches.
Structure of the Organ of Corti
The organ of Corti is a complex structure that is responsible for hearing. It is located in the inner ear, and it is made up of several different types of cells. The organ of Corti is divided into two main parts: the tectorial membrane and the basilar membrane.
The tectorial membrane is a thin, gelatinous membrane that covers the hair cells of the organ of Corti. The hair cells are the sensory cells of the organ of Corti, and they are responsible for converting sound waves into electrical signals. The basilar membrane is a thin, elastic membrane that underlies the hair cells. The basilar membrane vibrates in response to sound waves, and this vibration causes the hair cells to move.
The organ of Corti is also divided into three regions: the inner hair cell region, the outer hair cell region, and the pillar cell region. The inner hair cell region contains the inner hair cells, which are responsible for hearing high-frequency sounds. The outer hair cell region contains the outer hair cells, which are responsible for hearing low-frequency sounds. The pillar cell region contains the pillar cells, which support the hair cells.
The organ of Corti is a very sensitive structure, and it is capable of detecting sound waves over a wide range of frequencies. The organ of Corti is also very efficient, and it is able to convert sound waves into electrical signals with very little distortion.
Cellular Components of the Organ of Corti
The organ of Corti is composed of several different types of cells, including:
- Hair cells: The hair cells are the sensory cells of the organ of Corti. They are responsible for converting sound waves into electrical signals.
- Supporting cells: The supporting cells support the hair cells and help to maintain the structure of the organ of Corti.
- Nerve fibers: The nerve fibers carry the electrical signals from the hair cells to the brain.

Function of the Organ of Corti
The organ of Corti is responsible for hearing. It converts sound waves into electrical signals that are sent to the brain. The brain then interprets these signals as sound.
The organ of Corti is a very sensitive structure, and it is capable of detecting sound waves over a wide range of frequencies. It is also very efficient, and it is able to convert sound waves into electrical signals with very little distortion.
Question 1: What is the purpose of the organ of Corti?
Answer: The organ of Corti is a sensory structure located in the inner ear that is responsible for converting sound waves into electrical signals that are sent to the brain.
Question 2: What are the different types of cells in the organ of Corti?
Answer: The organ of Corti contains several types of cells, including hair cells, supporting cells, and inner and outer phalangeal cells.
Question 3: How does the organ of Corti respond to different frequencies of sound?
Answer: The organ of Corti responds to different frequencies of sound by activating different groups of hair cells, which then send corresponding electrical signals to the brain.
Well, folks, there you have it! The Houses of Organ of Corti – a fascinating journey through the inner workings of our hearing. It’s like a whole tiny city in our ears, responsible for translating sound waves into electrical signals that our brain can interpret. Hope you enjoyed the little tour.
