Rafiel decides to pick up a book from the table. Which type of muscle tissue is responsible for this voluntary movement?

• Skeletal muscle

• Smooth muscle

• Cardiac muscle

• Nervous tissue

During a biology class, Sophia learns about the different types of muscle tissues in the human body. Her teacher, Mr. Gomez, asks her: What type of muscle tissue is found in the walls of the heart?

• Skeletal muscle

• Smooth muscle

• Cardiac muscle

• Connective tissue

Lauren and Hailey are running a race and their bodies needs to move quickly and efficiently. Which primary function of skeletal muscle tissue allows them to do this?

• Involuntary movement

• Contracts to pump blood

• Voluntary movement, produces heat, protects organs

• Regulates flow of blood in arteries by contraction

Liv is learning about how her stomach and intestines move food along without her thinking about it. Which type of muscle tissue is responsible for these involuntary movements in the walls of her major organs?

• Skeletal muscle

• Cardiac muscle

• Smooth muscle

• Striated muscle

While studying for her biology exam, Mikayla reads about structures in the heart that help cardiac muscle cells work together. What are intercalated discs?

• Cell structures that store energy.

• Specialized cell junctions in cardiac muscle.

• Protein fibers in smooth muscle.

• Nuclei in skeletal muscle cells.

While studying for her biology exam, Brianna looks at a diagram of muscle tissues. She wonders how smooth muscle cells are described in terms of shape. What is the correct description?

• Round

• Square

• Spindle shaped

• Triangular

Marcus notices his stomach churning after eating a big meal. What type of movement is the smooth muscle tissue in her stomach responsible for?

• Voluntary movement

• Involuntary movement

• Reflexive movement

• Coordinated movement

Nicolas is outside on a cold winter day without a jacket. He notices that his body starts to react to the cold. What is the term for the involuntary contraction of his skeletal muscles in response to the cold?

• Shivering

• Sweating

• Breathing

• Blinking
