All muscles, regardless of the particular type, can contract— that is, shorten. When muscles contract, some part of the body or the entire body moves. Humans have three types of muscles: smooth, cardiac, and skeletal (Fig. 7.1). The contrac- tile cells of these tissues are elongated and therefore are called.

There are three varieties of human of muscles: skeletal, smooth, and cardiac.

B) two cardiac muscle cells are connected by gap junctions. C) the cell membranes of two cardiac muscle fibers are completely separated by a synapse. D) the myofibrils are loosely attached to the membrane of the disc. E) All of the answers are correct.

Smooth muscle tissue, unlike skeletal or cardiac tissues, does not have clearly defined striations visible on the cells. This is because smooth muscle cells are organized in a different way than other muscle cells. As seen in the image below, the actin and myosin filaments in smooth muscle are arranged in a stacked pattern across the 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.Muscle: The Three Types of Muscle. Contractility is a fundamental property of cells and the majority of them contain essentially the same contractile machinery as that found in muscle cells.

Each level of the organization of a skeletal muscle is wrapped in a connective tissue layer: the cell (myofiber) is surrounded by the endomysium, the bundle of cells (muscle fascicle) is surrounded by the perimysium, and the organ (muscle) is surrounded by the epimysium.2.2 SR organizational features in striated muscle. Striated muscle cells possess a highly specialized architecture, in consonance with their mechanical function. Skeletal myocytes fuse into one long muscle fiber, and the arrangement of several of these fibers ultimately forms a muscle. Cardiomyocytes, on the other hand, do not fuse, and form ...
