Sound waves enter the outer ear and are transmitted through the auditory canal to the eardrum.The resulting vibrations are moved by the three small ossicles into the cochlea, where they are detected by hair cells and sent to the auditory nerve.. As the sound waves hit the eardrum, the sensory information goes into an air-filled cavity through lever-teletype bones called ossicles. Definition.

Cilia may be fused in short transverse rows to form membranelles or in tufts to form cirri. They also help particles move past the cell. These other senses are touch, taste, smell, and our sense of body position and movement (proprioception). These structures are important in the cell cycle and replication, and cilia play a vital part in human and animal development and in everyday life. The temporal lobes are the second largest lobe of the human cerebrum, accounting for 22% of the overall brain's volume, and are associated with hearing, memory, emotion, and some aspects of language.
