The Three Types of Muscles in the Human Body

The video tutorial explains the three types of muscles in the human body: skeletal, smooth, and cardiac. Skeletal muscles are voluntary and striated, working in pairs to facilitate movement. Smooth muscles are involuntary and found in organs like the bladder and intestines. Cardiac muscles, also involuntary, are unique to the heart and function continuously throughout life.

What type of muscles are responsible for voluntary movements?

• Involuntary muscles

• Skeletal muscles

• Cardiac muscles

How do skeletal muscles typically function in the body?

• They work independently

• They are always relaxed

• They work in pairs

• They do not contract

Which type of muscle is found in the bladder and intestines?

• Voluntary muscle

• Smooth muscle

• Skeletal muscle

• Cardiac muscle

What is a characteristic feature of smooth muscles?

• They are striated

• They appear smooth

• They are voluntary

• They have bands

Where is cardiac muscle exclusively found?

• In the arms

• In the heart

• In the legs
