1) Compare and contrast the structural characteristics of the three different types of muscular tissue.

Answer:

Difficulty: Hard

Study Objective 1: SO 10.1 Compare the structure and properties of the three types of muscular tissue.

Study Objective 2: SO 10.1.1 Explain the structural differences among the three types of muscular tissue.

Section Reference 1: Sec 10.1 Overview of Muscular Tissue

Solution: Both cardiac and skeletal muscle tissues are striated and smooth muscle is not, hence its name. Skeletal muscle cells have more than one nucleus, are large and run parallel to each other. Cardiac muscle cells usually have only one, sometimes two, centrally located nuclei and are branched. They also are connected to each other via gap junctions. Smooth muscle cells are small but form thick layers of hollow organs. Like cardiac muscle cells, some smooth muscle cells communicate via gap junctions. Skeletal muscle is voluntarily controlled while both cardiac and smooth muscle tissue are involuntary and autorhythmic.

Question type: Multiple Choice
