The striations that are evident in skeletal muscle are due to the areas between the sacromeres that is referred to as the Z-lines.keletal Muscle (as well as Cardiac Muscle) have striations do to their sarcomere's anatomy. The sarcomere is the functional unit of the muscle and appears striated because th â¦ e different thick and thin filaments present.
Review of the process in skeletal muscle: Skeletal muscle has a well-defined system for producing excitation of the skeletal muscle cells. An alpha-motoneuron innervates the muscle cell, forming a neuromuscular junction.n addition, the neurotransmitter can bind to any one of the nearby smooth muscle cells, a flexibility not found in the NMJ. The chemicals that influence smooth muscle cells: As you'll recall, there is only one neurotransmitter released at the neuromuscular junction-acetylcholine.
