Which body part serves as the communication highway between the body and the brain?
The spinal cord
How many lobes does the brain have?
4
What is the scientific name for the brain?
Cerebrum
Where are neurons found in the body?
In the brain, the spinal cord, and all throughout the body!
What is a neuron?
Neurons are the building blocks of the nervous system and acts as a chemical messenger that sends information through the nervous system
Name all the parts of the nervous system.
The brain, the spinal cord, and the nerves
What does the frontal lobe do?
The frontal lobe controls emotions, judgement, and decision making
I protect the brain and act as a cushion between the brain and the skull. What am I?
Cerebrospinal fluid
What do neurons send and receive?
Electrical impulses or signals
What does the myelin sheath do?
Insulates the axon and increases the speed of the electrical impulse
What is the name of the signal that the brain sends out to move body parts
motor output
Identify the yellow area.
The parietal lobe
What does the parietal lobe do?
The parietal lobe processes and interprets all sensory information
Which part of the neuron takes signals from other cells?
Dendrites
The DNA is found in this organelle
Nucleus
Describe what happens when someone is in an accident and can no longer walk or feel their legs.
An injury has occurred to their spinal cord which breaks the communication bridge between the brain and the highway. Because the bridge is broken, brain signals cannot reach the legs leading to paralysis
If I can no longer coordinate my movements and become unbalanced, which part of the brain is affected?
The cerebellum
Identify the green area of the brain
The temporal lobe
Identify number 4
Axon
Identify number 5
Axon terminal
What are the nerves called that are located in our extremities (our fingers and toes)
Peripheral nerves
What two parts make up the brain stem? (Hint: We talked about it briefly during the dissection)
Medulla oblongata and the pons
Where is the arbor vitae located?
Cerebellum
List the parts of the neuron that an electrical signal goes through in the correct order
Dendrites, cell body, axon, axon terminals
This is the last place an electrical signal goes through before being sent to another cell. What am I?
Axon terminal
