| Question | Answer |
|---|---|
| the parietal lobe controls _____ | Processes touch, temperature and pain. |
| the temporal lobe controls _____ | Processes hearing and helps with memory. |
| the frontal lobe controls _____ | Controls planning, decision-making and movement. |
| What does the occipital lobe do? | Processes vision. |
| What are the four main brain structures? | Cerebrum, cerebellum, brainstem and spinal cor |
| What does the cerebellum do? | Controls balance and coordination. |
| What does the cerebrum do? | Controls thinking, memory, senses and voluntary movement |
| What does the brainstem do? | Controls automatic functions like breathing and heart rate. |
| What does the spinal cord do? | carries messages between the brain and body. |
| What does the primary motor cortex do? | Controls voluntary movements. |
| What does the primary auditory cortex do? | Processes sounds. |
| What does the primary visual cortex do? | Processes visual information. |
| What are the two main divisions of the nervous system? | Central nervous system (CNS) and peripheral nervous system (PNS). |
| What is the CNS? | The brain and spinal cord. |
| What is the PNS? | All the nerves outside the brain and spinal cord. |
| What does the sympathetic nervous system do? | Prepares the body for fight or flight. |
| What does the parasympathetic nervous system do? | Helps the body rest and relax. |
| What are the three types of neurons? | Sensory, interneuron and motor neurons. |
| What does a sensory neuron do? | Carries information from the senses to the CNS. |
| What does an interneuron do? | Connects neurons inside the CNS. |
| What does a motor neuron do? | Carries messages from the CNS to muscles or glands. |
| What do dendrites do? | Receive messages from other neurons. |
| What does the cell body do? | Keeps the neuron alive and functioning. |
| What does the axon do? | Carries messages away from the cell body. |
| What does the myelin sheath do? | Insulates the axon and speeds up messages. |
| What do axon terminals do? | Release neurotransmitters to pass messages on. |
| What is a synapse? | The tiny gap between neurons. |
| How does a message cross a synapse? | Neurotransmitters cross the gap and bind to receptors on the next cell. |
| What is an excitatory neurotransmitter effect? | Makes the next neuron more likely to send a message. |
| What is an inhibitory neurotransmitter effect? | makes the next neuron less likely to send a message. |
