The pathway leading to the perception of sound by mammals begins with the
A) hair cells of the organ of Corti, which rests on the basilar membrane, coming in contact with the tectorial membrane.
B) hair cells of the organ of Corti, which rests on the tympanic membrane, coming in contact with the tectorial membrane.
C) hair cells of the organ of Corti, which rests on the tectorial membrane, coming in contact with the basilar membrane.
D) hair cells of the organ of Corti coming in contact with the tectorial membrane as a result of fluid waves in the cochlea causing vibrations in the round window.
E) hair cells on the tympanic membrane that stimulate the tectorial membrane neurons, leading to the auditory section of the brain.

The pathway leading to the perception of sound by mammals begins with the hair cells of the organ of Corti, which rests on the basilar membrane, coming in contact with the tectorial membrane. This occurs as a result of fluid waves in the cochlea causing vibrations in the basilar membrane, which stimulates the hair cells to move and come in contact with the tectorial membrane. This movement generates electrical signals that travel through the auditory nerve to the brain, where they are interpreted as sound.
