Muscle and Nerve Tissue

Muscle tissue is composed of cells that have the ability to _________________.

• contract

• expand

• divide

• secrete

Cardiac muscle is found in the ________________ and is responsible for ________________.

• Cardiac muscle is found in the heart and is responsible for pumping blood.

• Cardiac muscle is found in the lungs and is responsible for oxygen exchange.

• Cardiac muscle is found in the brain and is responsible for processing information.

• Cardiac muscle is found in the stomach and is responsible for digestion.

Smooth muscle is found in ________________ and helps with ________________.

• Smooth muscle is found in the walls of hollow organs (such as the intestines, bladder, and blood vessels) and helps with involuntary movements such as peristalsis and regulating blood flow.

• Smooth muscle is found in the heart and helps with pumping blood throughout the body.

• Smooth muscle is found in the skeletal system and helps with voluntary movements.

• Smooth muscle is found in the skin and helps with temperature regulation.

Which type of muscle tissue is voluntary?

• Cardiac

• Smooth

• Skeletal

Which type of muscle tissue has striations?

• Skeletal

• Smooth

• Both A and B

Identify the type of muscle tissue shown in the image.

• Skeletal Muscle

• Cardiac Muscle

• Smooth Muscle

• Connective Tissue

The role of smooth muscle in the digestive system is to:

• A) Secrete digestive enzymes

• B) Absorb nutrients

• C) Propel food through the digestive tract

• D) Neutralize stomach acid

What makes cardiac muscle unique compared to other types?

• It is voluntary and striated.

• It is involuntary and non-striated.

• It is involuntary and striated.

• It is voluntary and non-striated.

Match each muscle tissue with its function or location:

• Voluntary movement, attached to bones.

• Cardiac muscle

• Involuntary movement in organs like the digestive tract and blood vessels.

• Smooth muscle

• Found in the heart, pumps blood.

• Skeletal muscle

A patient experiences weakened heart contractions. Which type of muscle might be affected and why?

• Skeletal muscle, because it is responsible for voluntary movements.

• Smooth muscle, because it controls involuntary actions in organs.

• Cardiac muscle, because it is responsible for heart contractions.

• Connective tissue, because it supports and binds other tissues.
