Can You Hear Me Now?

Audition: The sense of hearing. Pitch: How high or low a sound is. Timbre: The complexity of the sound. Intensity: How loud a sound is. Decibels: The measure of how loud a sound is (its intensity).

8. Hair Cells: Receptor cells for hearing found in the cochlea. 6. Eardrum: A piece of skin stretched over the entrance to the ear; vibrates to sound. 7. Cochlea: A snail shaped part of the ear, filled with fluid and small hairs that vibrate to incoming sound. 8. Hair Cells: Receptor cells for hearing found in the cochlea. 9. Cilia: Hair like extensions on cells. 10. Auditory Nerve: Bundle of nerves carrying sound to the brain. https://www.youtube.com/watch?v=k4O-75E9Jn8

How are Smell and Taste Connected?

Olfaction: The sense of smell. Olfactory Bulbs: Units that receive odor molecules and communicate their nature to the brain. Pheromones: Odor chemicals that communicate a message. Taste receptors: Chemical receptors on the tongue that decode molecules of food or drink to identify them.
