Sense of gravity
What is the term for the sense of taste?
Gustation
Gustation is one of the five traditional senses and involves the detection of flavor compounds in substances that come into contact with taste buds.
What is the spiral organ commonly known as?
Organ of Corti
The organ of Corti is the sensory organ located within the cochlea of the inner ear, responsible for converting sound vibrations into neural signals.
What is the Cochlear Nerve?
The Cochlear Nerve is a sensory nerve that carries auditory information from the cochlea to the brain.
