All of the answers are correct. In the heart, valves are located _____.Skeletal Muscle Tissue. The striations are evidence of the myofilaments inside the muscle fibers. The position of the nuclei and vascularity are also signs of muscle tissue. You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue. Lining this lumen, the cells seem to have long, fingerlike projections.

Striated versus smooth musclestriated muscle (striped muscle, skeletal muscle, voluntary muscle) Muscle that is composed of large, elongated cells (muscle fibres), each with many nuclei, in which the cytoplasm is marked by fine lines (striations) at right angles to the long axis.The striations occur because the cytoplasm contains many myofibrils, each of which is made from …

Structure of Myofibers . Structural and physiologic features of skeletal muscle determine much of its response to injury. Although muscle cells are frequently called muscle fibers or myofibers, they are in fact multinucleated cells of considerable length, which in some animals may approach 1 m.Myonuclei are located peripherally in the cylindrical myofiber (Fig. 15-1) and direct the physiologic ...The muscles all begin the actual process of contracting (shortening) when a protein called actin is pulled by a protein called myosin. This occurs in striated muscle (skeletal and cardiac) after specific binding sites on the actin have been exposed in response to the interaction between calcium ions (Ca ++) and proteins (troponin and tropomyosin) that "shield" the actin-binding sites.Chapter 4, Tissues, introduced the three major types of muscle cells: smooth, cardiac, and skeletal.

Jesse is biking down the road when the wind picks up.Smooth muscle does not contain regular striations or undergo the same type of excitation–contraction coupling. Instead, it typically uses second messenger signaling to open intracellular channels that release the calcium ions that control the contractile apparatus. ... In all muscle cells, contraction thus depends on an increase in cytosolic ... The actin and myosin proteins are arranged very regularly in the cytoplasm of individual muscle cells (referred to as fibers) in both skeletal muscle and cardiac muscle, which creates a pattern, or stripes, called striations.
