Final answer:
The concavity on the tympanic membrane where the malleus attaches is called the Umbo. The malleus is one of the three auditory ossicles, which are essential in transferring sound vibrations from the tympanic membrane to the inner ear for hearing.The correct option is:
a) Incus fossa
Step-by-step explanation:
The term that describes the concavity on the tympanic membrane where the malleus is attached is the Umbo. The tympanic membrane, otherwise known as the eardrum, is a thin diaphragm that vibrates when sound waves reach it. The malleus, also known as the hammer, is one of the three auditory ossicles in the middle ear, which include the malleus (hammer), the incus (anvil), and the stapes (stirrup).
The malleus attaches to the tympanic membrane and transfers the vibrations from the membrane to the other ossicles, which then transmit the vibrations to the fluid-filled cochlea, ultimately leading to sound perception.The correct option is:
a) Incus fossa
