Hearing / Balance
Sound vibrations enter the ear through this structure
What is the pinna / ear canal?
These receive a piece of food and send a signal to the brain
What are taste buds?
This is the first thing light passes through to our eyes
What is the cornea?
These structures can detect sound of different pitches depending on their size
What are hair cells?
These are what grab onto scent particles in the nose
What are hair cells / cilia?
This sends a message between the eye and the brain
What is the optic nerve?
These 3 bones amplify the sound into the inner ear
What are the malleus, incus, and stapes?
These are created by the olfactory bulb to send to the brain
What are electrical signals / action potentials?
This structure gets bigger or smaller depending on the amount of light
What is the pupil?
These structures hold fluid which tells us what direction our body is facing
What are the semicircular canals?
The olfactory receptor detects this type of signal
What is a chemical receptor?
This is where the image is projected in our eye
What is the retina?
The inner ear transforms this type of energy / waves into another type of energy / signals
What are sound waves to electrical signals?
This commonly breaks due to force to the nose and may result in a loss of smell
What is the cribriform plate?
The eye changes this type of energy into another type of energy / signal
What is light energy to electrical signals?
When we touch something hot with our hand, our hand flinches away before we realize it is hot. Explain how this works using as much detail as possible.
When we touch something hot, the sensory receptors within our dermis send an electrical signal to the brain to translate what is being touched. Our brain then sends an emergency signal back to the muscles in our hand to tell it to move.
