1 Motor Neurons A motor neuron’s cell body is also often ... Finally, during hyperpolarization, as positive potassium ions continue to leave the cell, the neuron’s membrane potential becomes more ...

For example, some motor neurons in the spinal cord have ... by fusion of the apposed inner leaflets of the plasma membrane in glial cells, with no intervening cytoplasm (Figure 1B).

Neurons are cells that act as the brain's fundamental building blocks, transmitting information through electrical signals. When a neuron receives a stimulus, changes in membrane voltage (the ...
