Final answer:
A single presynaptic cell can communicate with multiple postsynaptic cells, allowing information to affect multiple cells. In the context of controlling skeletal muscle contractions, this is achieved through the motor pathway involving upper motor neurons and lower motor neurons.
Step-by-step explanation:
A single presynaptic cell communicating with multiple postsynaptic cells allows information to affect lots of other cells. In the context of neurons controlling skeletal muscle contractions, this is achieved through the motor pathway involving upper motor neurons and lower motor neurons. The upper motor neuron initiates the signal in the cerebral cortex, while the lower motor neuron carries the signal to the skeletal muscle via the spinal cord. This allows one neuron to control the contraction of multiple muscle fibers within a target muscle.
