All muscle cells contain striations..
Each skeletal muscle cell, also called a muscle fiber, develops as many embryonic myocytes fused into one long, multi-nucleated skeletal muscle cell. These muscle fibers are bound together into bundles, or fascicles, and are supplied with a rich network of blood vessels and nerves. The fascicles are then bundled together to form the intact muscle.

The nuclei are pushed off to the side of the fibers. The tissue looks very vascular. What type of tissue are you observing? and more.The actin doesn't produce energy, it is like a long fibre. The myosin uses energy to produce force. One myosin molecule with two heads produces about 1.4 picoNewtons (0.0000000000014 Newtons) of force when it changes conformation. Actin and myosin form fibres that are across the whole length of the muscle cell.And so, again, cardiac muscle tissue is going to be found in the heart. And so notice here, we're focusing in on the heart and we've got this micrograph here of cardiac muscle tissue. Now, the first thing that you should note is that cardiac muscle tissue is going to contain striations like skeletal muscle tissue.One of the most iconic images in biology is the cross-striated appearance of a skeletal muscle fiber. The repeating band pattern shows that all of the sarcomeres are the same length. All of the A bands are the same length and are located in the middle of the sarcomeres. Furthermore, all of the myofibrils are transversely aligned across the muscle fiber. It has been known for 300 yr that ...a) smooth muscle cell does not contain enough calcium to maintain contraction for long periods of time. Once four Ca++ ions bind to the calmodulin, the Ca- calmodulin complex binds to the myosin light chain kinase and activates it. b) a protein that in humans is encoded by the CALD1 gene.The cells are interconnected physically and electrochemically to act as a syncytium. Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm.

Gene Ontology Term: striated muscle cell development. The process whose specific outcome is the progression of a striated muscle cell over time, from its formation to the mature structure. Striated muscle cells contain fibers that are divided by transverse bands into striations, and cardiac and skeletal muscle are types of striated muscle.
The cells are interconnected physically and electrochemically to act as a syncytium. Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm.Skeletal muscle fibers can be quite large for human cells, with diameters up to 100 μ m and lengths up to 30 cm (11.8 in) in the Sartorius of the upper leg.
