In cardiac muscle, the impulses are in part controlled by pacemaker cells which releases impulses regularly. Differentiation: Composed of narrow tubular cells. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.. A skeletal muscle refers to multiple bundles of cells joined together called muscle fibers. These cells are further specialized into distinct types based on their location and functions. *. of the ratio between surface area and volume; as cell size increases, the SA:V ratio decreases meaning it becomes more difficult for substances to enter and exit the cell quickly. Actin is covered by two additional proteins, troponin and tropomyosin. Each muscle cell has distinct regions when viewed under a microscope. Neuron. Skeletal muscle cells perform tasks at higher contracting rates, using a lot of ATP, although periods of rest follow bouts of movement. The long, branched structure aids in this function as the impulses can be carried longer distances as well as connect to others easily. This means that without Ca2+ the muscle cell will be relaxed. “Medical gallery of Blausen Medical 2014”. Skeletal muscle is one of three major muscle types, the others being cardiac muscle and smooth muscle.It is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system.

Below is a blown up view of each sarcomere. A. Actin and Myosin control contractions in the heart B. SURVEY . The signals travel through the transverse tubules (T tubules in the picture below) after being received from a nerve and activates the SR. Mitochondria are densely packed throughout muscle cells, to provide a constant flow of ATP. The energy in the transverse tubules causes the SR to release of the Ca2+ it has built up, flooding the cytoplasm with calcium. There are two types of adipose cells, white and brown, which differ functionally and in the way they store fat droplets. The muscles allow independent movement and regulate biological functions such as digestion and heartbeat. Biology. Edit. The large number of mitochondria is very important in tissue respiration in the muscle cells (Remember, energy is required for muscle to contract) Long and tube-like hollow vessels to carry the water from roots to leaves.
