All muscle cells contain striations..
The structure of skeletal muscle cells also makes them unique among muscle tissues. Skeletal muscle cells develop from the fusion of many smaller cells during fetal development, resulting in long, straight muscle fibers that contain many nuclei. When viewed under the microscope, skeletal muscle cells appear to have a striped, or striated ...
Skeletal and cardiac muscle cells are called striated muscle because of the very regular arrangement of their intracellular contractile units, sarcomeres, at the light microscope (LM) and electron microscope (EM) levels. This regular arrangement imparts a cross-striated (or striped) appearance. Such an arrangement is not seen in smooth muscle ...Epithelial tissue; Connective tissue; Muscle tissue; Nerve tissue. The four types of tissues are similar in that each consists of cells and extracellular ...Ontogenesis of Striated Muscle. Harvey B. Sarnat, in Fetal and Neonatal Physiology (Fifth Edition), 2017 Sarcoplasmic Organelles. The abundant sarcoplasm (i.e., cytoplasm) within the core of the myotube between and around nuclei contains membranous organelles. These are mitochondria with well-formed cristae, Golgi apparatuses generally located at the end of a nucleus, and single-membrane vesicles.The term "muscle" covers a multitude of cell types, all specialized for contraction but in other respects dissimilar. As noted in Chapter 16, a contractile system involving actin and myosin is a basic feature of animal cells in general, but muscle cells have developed this apparatus to a high degree. Mammals possess four main categories of cells specialized for contraction: skeletal muscle ...

Visceral smooth muscle. a) may contain groups of cells that function as an independent unit.
Myocytes, sometimes called muscle fibers, form the bulk of muscle tissue. They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue. Muscles are composed of long bundles of Myocytes (Muscle fibers). Myocytes contain thousands of myofibrils.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.Study with Quizlet and memorize flashcards containing terms like Which of the following is not a type of tissue? a. muscle b. nervous c. embryonic d. epithelial, The process by which a less specialized cell matures into a more specialized cell is called ________. a. differentiation b. maturation c. modification d. specialization, Differentiated cells in a developing embryo derive from ...Figure 17.3.4 17.3. 4 show the spread of the electrical wave through these structures and the myocardial contractile cells.

Skeletal muscle cells are striated, meaning they have stripes or bands, due to the arrangement of their proteins. Which of the following is NOT characteristic of smooth muscle? Select one: a. the thin filaments of smooth muscle fibers are attached to dense bodies. b. smooth muscle cells are uninucleated. c. striations present are due to the orderly arrangement of actin and myosin. d. smooth muscle s do not contain sacromeres.Note that sometimes the cross striations are not aligned all the way across the cell. This is because different myofibrils may not be aligned.

Skeletal Muscle Fibers. Because skeletal muscle cells are long and cylindrical, they are commonly referred to as muscle fibers. Skeletal muscle fibers can be quite large for human cells, with diameters up to 100 μm and lengths up to 30 cm (11.8 in) in the Sartorius of the upper leg. During early development, embryonic myoblasts, each with its ...Unlike striated muscle cells, which are postmitotic, smooth muscle cells can proliferate under physiological and pathological conditions.
