tissue, is the main pathway for information travelling to and from
the brain. Unit 3 Lesson 3 How Do Cells Work Together?

Hearing 1.The outer ear funnels sound into the middle ear
causing the eardrum to vibrate. 2.Tiny bones ( hammer, anvil, and
stirrup) pass vibrations to the inner ear where a fluid-filled
structure called the cochlea passes vibrations to tiny hairs on the
nerves. 3.These nerves send messages about vibrations to the brain
and you hear. Copyright Houghton Mifflin Harcourt Publishing
