What is the main control center of the nervous system?


The brain

100

These specialized cells send electrical signals through the nervous system


Neurons 

100

This part of the nervous system includes the brain and spinal cord.


Central nervous system (CNS)

100

This quick automatic response helps protect the body from harm.


Reflex

200

 This part of the brain controls balance and coordination.


What is the cerebellum?


200

These chemicals carry messages between neurons across synapses


Neurotransmitters 

200

This system controls automatic body functions like heartbeat and digestion.


What is the autonomic nervous system?


200

This disease is caused by abnormal electrical activity in the brain that leads to seizures.


Epilepsy 

300

This lobe of the brain helps with decision-making and problem-solving.


What is the frontal lobe?


300

This protective covering around neurons helps speed up nerve impulses.


Myelin sheath

300

This division of the nervous system controls voluntary movements like walking and writing.


Somatic nervous system 

300

This type of neuron carries messages from sense organs to the brain and spinal cord


Sensory Neurons 

400

This lobe of the brain is mainly responsible for vision.


What is the occipital lobe?


400

This part of the neuron receives incoming signals from other neurons


Dendrites 


400

This branch of the autonomic nervous system prepares the body for “fight or flight.”


Sympathetic nervous system 

400

This support cell protects and nourishes neurons in the nervous system.


Glial cells

500

This disease causes nerve cells in the brain to break down and affects memory.


Alzheimer's disease

500

This gap between neurons is where neurotransmitters are released.


Synapse 

500

This branch of the autonomic nervous system calms the body after stress.


Parasympathetic nervous system

500

This structure carries messages between the brain and the rest of the body.


Spinal chord
