Textbook Question

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
The spiral organ is located in the scala tympani.

Verified step by step guidance

Step 1: Understand the anatomy of the cochlea, which is part of the inner ear. The cochlea contains three main chambers: the scala vestibuli, scala media (cochlear duct), and scala tympani.

Step 2: Learn the location of the spiral organ (also known as the organ of Corti). It is situated within the scala media, specifically on the basilar membrane.

Step 3: Compare the statement provided in the problem with the anatomical facts. The statement claims that the spiral organ is located in the scala tympani, which is incorrect based on the anatomy of the cochlea.

Step 4: Correct the false statement. The true statement should be: 'The spiral organ is located in the scala media.'

Step 5: Review the corrected statement and ensure it aligns with the anatomical structure of the cochlea and the function of the spiral organ in detecting sound vibrations.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Spiral Organ (Organ of Corti)

The spiral organ, also known as the organ of Corti, is a crucial structure within the cochlea of the inner ear. It contains hair cells that convert sound vibrations into neural signals, playing a vital role in the process of hearing. The organ is situated on the basilar membrane, which is located in the scala media, not the scala tympani.

Cochlea Anatomy

The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that is essential for hearing. It consists of three main chambers: the scala vestibuli, scala media, and scala tympani. Understanding the anatomy of the cochlea is important for identifying where various auditory structures, including the spiral organ, are located.

Scala Tympani

The scala tympani is one of the three fluid-filled chambers of the cochlea, located below the scala media. It is filled with perilymph and plays a role in transmitting sound waves from the oval window to the round window. The spiral organ is not located in this chamber, which is a common misconception.
