Sound Waves Quiz

What does the homunculus model demonstrate about our bodies?

• It demonstrates that bodies are shaped in a way to enable greater sensitivity where we have larger body parts.

  
  

•  It demonstrates the relative proportion of our sensory cortex devoted to areas of our body, depending upon their sensitivity.

What type of wavelength creates a high-pitched sound?

• short

• Long

The ______________ of the wave determines its loudness which is measured in decibels

• Height
• length

Which of the following best describes the process by which sound waves are transferred into perceivable sound?

• Sound waves travel through the air to the ear lobe, where they hit the 3 bones in the ear (the hammer, anvil, and stirrup). Which then hits the eardrum and funnels them into the ear canal. Then they go to the auditory nerve which sends information to the cochlea. At the cochlea, the hair cells transmit information to the auditory cortex which contains the parietal cortex.

• Sound waves travel through the air to the ear lobe, which funnels them into the ear canal. At this point, they hit the ear drum which vibrates the 3 bones in the ear (the hammer, anvil, and stirrup). These bones in turn send vibrations to the cochlea which has tiny hair like nerves that relay the information (transduction) along the auditory nerve to the auditory cortex in the temporal lobe.

What is umami?

• The taste of salt and sweet together.

• The taste of salt and sweet together.

• The word used to describe the tongue diagram seen in the crash course video

The principle that one sense influences another is known as:

• Sensory Interaction

• Sensory Cohesion

• A rare neurological condition which allows some people to have a consistent mixing of the senses, such as hearing colors.

What is synesthesia?

• A unique sense of touch associated with neurotransmitters that bind to the olfactory bulb.

  
  

• A rare neurological condition which allows some people to have a consistent mixing of the senses, such as hearing colors.

  
  

Unlike sight and hearing which are wave-detecting senses, these two are chemical senses:

• Taste

• Smell

• Taste and Smell

How many types of taste receptors do we have?

• 5

• 1

• 10

How is the sense of smell different from the other senses?

• Smell does not have a specific number of possible types and smell is heavily influenced by past experiences.

• Smell is associated with the auditory nerve and thus has a unique connection to sound.
