Chapter 4 The thtee types of muscle tissue in the body are skeletal muscle tissue, cardiac muscle tissue, and smooth muscle tissue. Which type of muscle tissue has small, tapering cells with single nuclei and no obvious striations? Muscle tissue containing small, tapering cells with single nuclei and no obvious striations is smooth muscle tissue. Irregularly shaped cells with many fibrous projections, some several centimeters long, are probably which type of cell?

"""Define The Terms Skeletal Muscle Fiber Motor Unit Skeltal Muscle Twitch"" Essays and Research Papers" There are three types of muscle tissue: skeletal, smooth, and cardiac. Skeletal muscle tissue is a voluntary type of muscle tissue that is used in the contraction of skeletal … parts. It is striated (alternating with light and dark bands, called striations) and is attached to bones.A single skeletal muscle fiber is very long and has many nuclei, located at the periphery of the cell.IMPROVED ANSWER:  Skeletal muscle is a type of striated muscle, which usually attaches to tendons. Skeletal muscles are used to create movement, by applying force to bones and joints via contraction.

Muscle Cell Types Four characteristics define skeletal muscle tissue cells: they are voluntary, striated, not branched, and multinucleated. Skeletal muscle tissue is the only muscle tissue under the direct conscious control of the cerebral cortex of the brain, giving it the designation of being voluntary muscle.our characteristics define cardiac muscle tissue cells: they are involuntary and intrinsically controlled, striated, branched, and single nucleated. Cardiac muscle is considered to be an involuntary tissue because it is controlled unconsciously by regions of the brain stem and hypothalamus.

- The A and I bands repeat along the length of the muscle fibers to create the striations visible under the light microscope. 1  Sarcomeres repeat along skeletal and cardiac fibers. 2  Components between adjacent Z-lines comprise the sarcomere. 3  Sarcomeres are considered the functional units of striated muscles.n views of this muscle type, striations are not as strong as those of skeletal muscle. Other structural features are usually apparent and of use for identification if the striations are weak. Due to constant activity cardiac muscle has a constant need for oxygen and glucose delivery.

What Organelle Must Be Present in Large Numbers in Muscle Cells? Muscle cells have special characteristics that make them more effective in their primary task of accomplishing movement through contraction. The three general types of muscle tissue -- smooth, cardiac and skeletal -- all contain elongated cells known also as muscle fibers.

- Cardiac myofibers also contain a single, centrally located nucleus in contrast to the multiple peripheral nuclei of skeletal muscles. In summary then, cardiac muscle consists of branching myofibers with single, centrally placed nuclei.

- Do not mistake adipose cells with skeletal muscle in cross-section. The former appear as empty cells with single peripheral nuclei while skeletal muscle cells typically have a granular or spotted internal appearance due to the numerous myofibrils.

- Both skeletal muscles and cardiac muscles contain striations among muscle cells and produce strong contractions, according to class notes from Yale University. Striations occur in crossing, alternating light and dark bands produced by proteins that make muscles contract, according to Dictionary.com. Continue Reading.

Skeletal Muscle Skeletal Muscle. Skeletal muscle is composed of large, cylindrical, multinucleated cells. The most striking feature of skeletal muscle fibers is the presence of striations, which are visible in longitudinally sectioned fibers. The striations are due to the presence of. , which are cylindrical bundles of thick and thin myofilaments, organized into units of contraction called. .

Muscle Cardiac and skeletal muscles are striated in that they contain sarcomeres that are packed into highly regular arrangements of bundles; the myofibrils of smooth muscle cells are not arranged in sarcomeres and so are not striated.

- In striated muscle, such as skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length in the order of a few micrometers, far less than the length of the elongated muscle cell (a few millimeters in the case of human skeletal muscle cells).yofilaments are the filaments of myofibrils, constructed from proteins, principally myosin or actin. Types of muscle are striated muscle (such as skeletal muscle and cardiac muscle), obliquely striated muscle (found in some invertebrates), and smooth muscle.

- Striated skeletal muscle is formed by the fusion of myoblasts into large, long, multinucleated structures called myotubes. The myotubes subsequently synthesize proteins and fill the cytoplasm with myofibrils. In the early development of the myotube, the nuclei are in the center of the cell.

What is a smooth muscle? Smooth muscle ((unlike skeletal muscle) consists of individual cells (leiomyocytes), each cell with its own nucleus. The function of smooth muscle also differs substantially from that of striated muscle. Neurotransmitter activitation of smooth muscle is fairly diffuse.

What Are Examples of Involuntary Muscles? The structure of an involuntary muscle cell consists of a long, spindle-shaped cell without striations. The cells may occur as individual cells, in groups or as sheets. Contractions occur either in slow, spontaneous rhythms or as sustained contractions for longer durations. The involuntary muscle is one of three types of muscles found. The other two types are skeletal and cardiac. Skeletal muscle is a type of voluntary muscle, meaning it is controlled by the organism's will. The skeletal muscle is also referred to as a striated muscle because of the alternating muscle fibers that are light and dark colored.

- When cut in longitudinal section, smooth muscle nuclei appear very long and sometimes wiggly (due to contraction). In cross-sectioned smooth muscle, only a fraction of the fibers display nuclei. Recall that each smooth muscle fiber is a single cell, each with its own nucleus. In each such cell, the nucleus occupies only a small proportion of the cell's total length. So nuclei appear only in a similarly small proportion of the fibers cut by any single section. A very small bundle of smooth muscle can be particularly inconspicuous when cut in cross section.

- Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure, function, regulation of contraction, and excitation-contraction coupling. Smooth muscle cells known as myocytes, have a fusiform shape and, like striated muscle, can tense and relax. However, smooth muscle tissue tends to demonstrate greater elasticity and function within a larger length-tension curve than striated muscle.

Histology@ Yale Skeletal muscle comprises several different types of muscle cells. These cells differ in their rate of contraction and metabolic activities. This cross section of skeletal muscle was stained to label slow-twitch muscle fibers (type I). These cells express muscle myosin that has a slow ATPase rate and are adapted for long, slow contraction. The lighter staining muscle cells express muscle myosin that has a fast ATPase rate.

The Muscular System: How We Move Around Furthermore, cardiac muscle cells also have intercalated disks, or desmosomes, that allow the cells to stick together. Skeletal muscle cells and cardiac cells have striations (or divisions) but that is where the similarities end. When you think of muscles, the image that comes to mind is most likely a skeletal muscle. These muscle cells are long and have many nuclei. An example of a skeletal muscle would be your triceps and biceps.

Structure and Functions of Muscular Tissue : Skeletal muscle is called striated because of its appearance consisting of light and dark bands visible using a light microscope. As shown in the diagram (on the right), a single skeletal muscle cell is long and approximately cylindrical in shape, with many nuclei located at the edges (periphery) of the cell.
