So the neuron contains an axon, it contains dendrites, it contains the axon hillock, it contains the axon terminal, while the skeletal muscle contains a specialized type of cell membrane known as the sarcolema. It contains a specialized type of endoplasma take limb known as the sarcoplasma taylor. It also contains these long fibers made of actin as well as myosin. So what differentiates these two cells or any two specialized cells for that matter is the presence of different types of structures and components inside those cells. So it's those components that give these specialized cells their specific and unique characteristics. Now, all these different components are actually either formed by proteins or they are composed of proteins.
