Within muscles, there are layers of connective tissue called the epimysium, perimysium, and endomysium. These layers cover muscle subunits, individual muscle cells, and myofibrils respectively. The smallest unit of contraction is the sarcomere, where actin and ...

Muscle atrophy is the result of loss of.
Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sarcomere, produces these striations.. In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.. The terms muscle cell and muscle fiber are …Cardiac muscle fibers, or cardiomyocytes, like skeletal muscle fibers, are striated and have a single, central nucleus. However, two or more nuclei may be found occasionally. Transverse ( or T) tubules, the folds of the sarcolemma (plasma membrane), penetrate deep into the interior of the cell, allowing electrical impulses to reach the inner ...A muscle is composed of individual muscle cells that contain many muscle filaments (myofibrils). The filaments compose a muscle fiber. A skeletal muscle ...

Only the parietal membrane would continue producing serous fluid. d. The lung would get much larger than normal when inhaling air. a. Loss of membrane adhesive force would cause lung collapse. A smooth muscle cell is a spindle-shaped myocyte with a wide middle and tapering ends, and a single nucleus. Like striated muscle, smooth muscle can tense and relax. In the relaxed state, each cell is 30–200 micrometers in length, some thousands of times shorter than a skeletal muscle cell.
