Leila and liam are twins and spent their 16th birthday at their favorite amusement park. after riding the biggest and fastest roller coaster in the park, leila and liam feel very dizzy and disoriented. which of the following would play the biggest role in these feelings?

olfactory receptors
basilar membrane
semicircular canals
cones and rods
sensory receptors of the joints

The correct answer is C. Semicircular canals.

Explanation

The semicircular ducts are a part of the inner ear, they are small ducts that contain fluid inside. The semicircular ducts work when they undergo a movement, causing the liquid inside to move and touch the small hairs inside. These hairs send a nervous signal to the brain so that it determines how to maintain the body's balance.

An example of this is the case of Leila and Liam, who underwent a roller coaster movement, causing the liquid in their semicircular ducts to move and touch the hairs in the ducts, sending a nervous message to the brain, this continues even when they get off the roller coaster, that is why Leila and Liam continue to feel that sensation of movement and dizziness. So, the correct answer is C. Semicircular canals.
