Verified step by step guidance
1
Step 1: Begin by understanding the structure of the inner ear. The inner ear consists of the membranous labyrinth, which is a system of interconnected sacs and ducts filled with endolymph fluid. It is housed within the bony labyrinth.
Step 2: Identify the components of the membranous labyrinth. These include the utricle, saccule, semicircular ducts, and cochlear duct (scala media). These structures are involved in balance and hearing.
Step 3: Recognize that the tympanic membrane, also known as the eardrum, is not part of the membranous labyrinth. It is located in the middle ear and functions to transmit sound vibrations to the ossicles.
Step 4: Compare the listed options to the components of the membranous labyrinth. The utricle, semicircular ducts, and cochlear duct are all part of the membranous labyrinth, while the tympanic membrane is not.
Step 5: Conclude that the correct answer is the tympanic membrane, as it is not a component of the membranous labyrinth of the inner ear.
