Dendrites and the Cell Body
Captions available
The idea
Dendrites receive incoming signals and carry them to the cell body, which integrates them and holds the neuron's nucleus.
In practice
Thousands of dendritic branches on one motor neuron collect signals arriving from many other neurons at once.
Where people slip
Integration is not addition. Some incoming signals push the neuron toward firing and others push it away.
