A-Semicircular canals
The correct answer is A- Semicircular canals. The semicircular canals in the inner ear consist of three tubes filled with fluid that sloshes through them when the head moves. This movement of fluid signals rotational or angular movement to the brain. Anvils, stirrups, and hammers are actually small bones located in the middle ear and are involved in the transmission of sound vibrations.
The correct answer is A) Semicircular canals.
To arrive at this answer, it is important to understand the functions and components of the inner ear. The semicircular canals are part of the vestibular system, which is responsible for detecting changes in head position and movement. The inner ear contains three semicircular canals, each oriented in a different plane. These canals are filled with a fluid called endolymph.
When the head moves or rotates, the inertia of the endolymph causes it to slosh through the semicircular canals. This movement of fluid stimulates hair cells in the canals, which then send electrical signals to the brain to indicate rotational or angular movement. These signals are important for maintaining balance and coordination.
On the other hand, options B, C, and D (Anvils, Stirrups, and Hammer) are not part of the inner ear's semicircular canals. Instead, they are the three small bones in the middle ear known as the ossicles: the incus, stapes, and malleus. The ossicles play a role in transmitting sound vibrations from the eardrum to the inner ear, specifically to the cochlea.
Therefore, the correct answer is A) Semicircular canals, which are the tubes in the inner ear that contain fluid and signal rotational or angular movement to the brain.
