BIO 161 PSU EXAM 4 QUESTIONS AND ANSWERS 100% PASS Question: Name the three types of muscle tissue found in the human body. - a. skeletal, cardiac, striated - b. voluntary, smooth, cardiac - c. skeletal, cardiac, smooth - d. striated, smooth, involuntary - Answer: c. skeletal, cardiac, smooth Explanation: The human body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle, each with distinct characteristics and functions. Question: What are some features of skeletal muscle tissue? - a. Involuntary, non-striated - b. Voluntary, striated, multinucleate - c. Involuntary, striated, autorhythmic 2 - d. Voluntary, non-striated, mononucleate - Answer: b. Voluntary, striated, multinucleate Explanation: Skeletal muscle tissue is characterized by its voluntary nature, striated appearance under a microscope, and multinucleate cells. It is typically attached to bones or fascia. Question: What are some characteristics of cardiac muscle tissue? - a. Voluntary, striated, multinucleate - b. Involuntary, non-striated, mononucleate - c. Involuntary, striated, autorhythmic - d. Voluntary, non-striated, multinucleate - Answer: c. Involuntary, striated, autorhythmic Explanation: Cardiac muscle tissue is involuntary, striated, and characterized by cells that can self-regulate their contractions (autorhythmic). Question: List five properties that describe muscle tissue. 3 - a. irritability, conductivity, contractility, extensibility, elasticity - b. excitability, conductivity, distensibility, elasticity, viscosity - c. excitability, conductivity, contractility, extensibility, viscosity - d. irritability, conductivity, compressibility, extensibility, elasticity - Answer: a. excitability, conductivity, contractility, extensibility, elasticity Explanation: Muscle tissue exhibits excitability (responsiveness to stimuli), conductivity (propagation of electrical signals), contractility (ability to shorten and generate force), extensibility (capability to stretch without damage), and elasticity (ability to return to its original shape after stretching).
