NEURONS

DENDRITES

• The extensions that branch of the cell body
• They receive info from sensory organs
• In the model, dendrites are the parts that stick out
• With out dendrites we wouldn't be able to function

AXON

• It's the large stem in the middle of the neuron
• Each neuron only only has one
• There are Schwann cells and the myelin sheath
• The node of ranvier connects each myelin sheath together
• On one end there is a dendrite, and an axon terminal

AXON TERMINAL

• Ends one side of axon
• Forms a synapses with other neurons
• The axon terminal is the ending part of our model
• There are neuron transmitters at the end of the axon terminal
• This is where the synapses is formed

SYNAPSES

• They contain transmitters
• The message passes through the axon is tran
• -smitted to the next cell through a junction which is the synapses
• It is very important

MYELIN SHEATH

• It's a fat layer surrounding the axon
• It is protection for the axon

NODE OF RANVIER

• It is the white part
• It connects the axon pieces

SCHWANN CELL

• It is in the myelin sheath

NUCLEUS

• Contains DNA and genes
• Every cell has one
• It is the dot on the end of the axon
• It's beside the dendrites

QUESTIONS

• What's a nucleus?
• What do dendrites do?
• Where is axon on the neuron?
• What are neurons for?
