Rough Surface (dendritic spines) 
Usually many dendrites per cell

Question 10

Neurones are similar to other cells in the body because

Answer 10

Neurons are surrounded by a cell membrane.
Neurons have a nucleus that contains genes.
Neurons contain cytoplasm, mitochondria and other organelles.
Neurons carry out basic cellular processes such as protein synthesis and energy production.

Question 11

Neurones differ from other cells in the body because:

Answer 11

Neurons have specialised extensions called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body.
Neurons communicate with each other through an electrochemical process.
Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).
