What part of the brain is labelled 1?
The Cerebrum
100
what are the three main sections of the ear?
Outer, Middle and Inner Ear
100
What is labelled 'd' in the diagram?
The pupil
100
Messages are sent to the bran through a network of nerve cells called what?
Neurons
100
Can you hear sound through a gas?
Yes. We hear through the air all the time
200
What part of the brain is labelled 2?
The Cerebellum
200
What is found inside the cochlea in the inner ear the ripples when vibrations hit it?
Liquid
200
What do the cones and rods found in the retina allow you to do?
Rods allow you to see shades of gray
Cones allow you to see colours
200
Neurons have long arms called what?
Axons
200
What did we notice playing the sounds game? Why did some people get the harder questions right while others didn't (hint: Kaleb and I both thought the bus was the subway...why?)?
- we are influenced by our experiences
- our senses usually work together but when you isolate one of our senses it makes it more difficult
- Kaleb and I had both taken a subway before and the doors to the bus sounded like subway doors opening and closing.
300
What part of the brain is labelled 3?
The Brain Stem
300
What sends messages from the inner ear to the brain (labelled K below)?
Auditory Nerve
300
What connects the eye to the brain (page 11)?
The Optic Nerve
300
The shorter arms of neurons are called what?
Dendrites
300
What does the word homeostasis mean (page 1)?
- a state of balance in the body
- the body is working the way it should
400
What are the important features of the cerebellum (number 2)?
The cerebellum controls balance, posture and coordination.
400
What are the names of the three bones in the middle ear (labelled D,E,F)?
The Hammer, Anvil, and Stirrup
400
Why are your eyebrows and eyelashes important?
Eyebrows protect the eye from sweat
Eyelashes keep dust, dirt, and other foreign objects out of the eye.
400
What is the middle, control centre of a neuron called?
Nucleus
400
Why is the brain stem important (labelled number 3) (page 4)?
- connects the brain to the spinal cord
- controls digestion, heartbeat, breathing, down temperature, and other important body functions
500
What are the important features of the cerebrum (number 1)?
- largest part of the brain
- allows us to speak, remember things, and solve problems
- allows us to hear, see, taste, smell, and touch
500
Describe as best you can how vibrations allow us to hear (page 17)?
- our auricle and auditory canal capture vibrations around us
- the vibrations make our ear drum vibrate
- the ear drum makes our hammer, anvil, and stirrup vibrate
- Liquid in our cochlea ripples which makes our cilia move and this signal goes from our auditory nerve to our brain
500
Describe how the iris, pupil and lens work together to control the light (Page 11)?
The iris is a muscle that adjusts the size of the pupil.
The pupil allows light to enter the eye and changes in size to adjust to the light
The lens changes shape to focus on objects
500
In your own words, why is it important for our bodies to have message transmitters?
- without nerve cells, our brain wouldn't be able to react to the world around us
- we wouldn't be able to breath or move our body
- we wouldn't be able to keep ourselves safe
- we wouldn't be able to use any of our senses
500
What three main things make up the nervous system (page 1)?
The brain, spinal cord, and nerve cells
