Figure 15.3.2 15.3. 2: Muscle type 1) Skeletal muscle cells are long tubular cells with striations (3) and multiple nuclei (4). The nuclei are embedded in the cell membrane (5) to be just inside the cell. This type of tissue occurs in the muscles that are attached to the skeleton.Unformatted text preview: striations that pass across the width of the smooth muscle cells. There is only one nuclei. Skeletal muscle fibers are longer than smooth muscle fibers. The smooth muscle is involuntary, the muscles cannot be contracted is what it means. It also means that you cannot control. The lining of the organs is the smooth tissue.Having a little muscle around your small business comes in handy when it's time to flex. * Required Field Your Name: * Your E-Mail: * Your Remark: Friend's Name: * Separate multipl...The absence of striation is also characteristic of the smooth muscle cells. How does the number and location of the nuclei in smooth muscle compare to that in striated muscle? Answer: Smooth muscle cells usually have one nucleus per cell and the nucleus resides in the center of the cell. Striated muscle cells contain multiple nuclei located at ...smooth muscle. The stomach is composed of smooth muscle cells. smooth muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically.

A very small bundle of smooth muscle can be particularly inconspicuous when cut in cross section. In that case, the cell nuclei appear as small round dots whose apparent size (about 3-4µm) and consistent ...A smooth muscle cell is smaller in size compared to skeletal muscle cells, generally ranging from 20 to 200 micrometres in length. It possesses a spindle-shaped or elongated shape with tapered ends. Unlike skeletal muscle cells, smooth muscle cells possess a single, centrally located nucleus. Step 2. 2 of 2.

In mammals, a ring of smooth muscle lies close to the pupillary edge of the iris. Individual smooth muscle cells are scattered within connective tissues or close to epithelia in many organs. The total amount of musculature in the body is difficult to calculate. On the basis of the estimates shown in Table 1, smooth muscle may represent 2% of ...

A smooth muscle looks like an elongated spindle-shaped or fusiform cell under a light microscope. Each cell of the smooth muscle fibers contains a single elongated center nucleus. The diameter of the smooth muscle cells ranges from 5 to 20 micrometers. In contrast, the length of these smooth muscle cells ranges from 20 …

The cardiac muscles are thick, and the muscle fibers making up this muscle have a striated, or _____, appearance.Why do smooth muscle fibers in cross section have different diameters and why do some of these fail to show nuclei? Smooth muscle cells have tapered ends. Since the cells interdigitate different diameters would be revealed in a particular plane of section and the plane of section does not always go through the nucleus.Skeletal muscles contain specialized proprioceptive sense organs, called muscle spindles, which function to detect muscle stretch.

Muscle is the tissue in animals that allows for active movement of the body or materials within the body. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Most of the body’s skeletal muscle produces movement by acting on the skeleton. Cardiac muscle is found in the wall of the heart ...A hallmark of the skeletal muscle cell is the position of nuclei at the periphery. After spreading, nuclei migrate from a central position within the myotube to the periphery. In the mammalian system, nuclear migration to the periphery occurs after the formation of myofibrils, the contractile fibers filling the cell.Leiomyoma with bizarre nuclei (LBN), also known as symplastic leiomyoma, is a histological subtype of benign leiomyoma with bizarre cells and nuclear atypia.
