The striations are dark and light stripes along the muscle cell due to the arrangement of the protein filaments, or myofilaments within the muscle fiber. Contractions of skeletal muscle can be regulated by conscious control, therefore, it is cons ...

That is, the neuron's plasma membrane does not actually touch the target cell's plasma membrane. This tiny area where the two membranes lie so close together is called the synapse. Th ...
