Answer:
Mechanoreception
Explanation:
Mechanoreception is usually defined as the ability of an organism, such as humans and animals, to perceive and react to certain types of stimuli. This may include a sensation like sound, touch, that are produced in an environment.
This involves the conversion of sound waves (which are mechanical vibrations) into nerve impulses which are in the form of electrical signals. Initially, this process starts with the vibration of the eardrum and immediately transmits these vibrations towards the three small bones that are located in the middle portion of the ear. These are then carried by the auditory nerve into the brain. The brain finally converts this information into electrical signals. This entire process eventually leads to the creation of sound within the temporal lobe inside the brain.
