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 work in pairs, such as the biceps and triceps. 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 is the primary characteristic of skeletal muscles?

• They are involuntary and smooth.

• They are voluntary and striated.

• They are found only in the heart.

• They are attached to tendons.

How do skeletal muscles typically function?

• They work in pairs, with one contracting and the other relaxing.

• They are always in a state of contraction.

• They contract and relax simultaneously.

• They work independently.

Where can smooth muscles be found in the body?

• Attached to bones.

• In the bladder and intestines.

• In the arms and legs.

• In the heart.

What is a unique feature of cardiac muscles?

• They are found in the intestines.

• They are voluntary and striated.

• They are fibrous and work continuously.

• They are attached to bones.

Which type of muscle is responsible for heart contractions?

• Skeletal muscle.

• Smooth muscle.

• Cardiac muscle.

• Tendon muscle.
