Muscle Types and Functions

The video tutorial explains the three types of muscles: smooth, cardiac, and skeletal. Smooth muscles are involuntary and found in organs like the stomach and intestines. Cardiac muscles, also involuntary, are found in the heart and help circulate blood. Skeletal muscles are voluntary, allowing for controlled movement, and are attached to bones via tendons. The video also emphasizes the importance of exercise and a balanced diet for strengthening skeletal muscles.

What is the primary characteristic of smooth muscles?

• They are under voluntary control.

• They are found in the heart.

• They work without conscious effort.

• They are attached to bones.

Where are smooth muscles typically located?

• In the heart

• In the arms

• In the brain

• In the stomach and intestines

What is the main function of cardiac muscles?

• To move bones

• To digest food

• To pump blood throughout the body

• To control breathing

Which type of muscle can you control consciously?

• Voluntary muscles

• Cardiac muscles

• Involuntary muscles

• Smooth muscles

What connects skeletal muscles to bones?

• Tendons

• Ligaments

• Nerves

• Cartilage

Which of the following is NOT a major skeletal muscle?

• Triceps

• Pectorals

• Biceps

• Liver

What role do tendons play in the muscular system?

• They digest food.

• They control breathing.

• They pump blood.

• They connect muscles to bones.

Why is it important to strengthen skeletal muscles?

• To control involuntary actions

• To improve digestion

• To enhance blood circulation

• To increase bone movement and strength

Which activity is NOT recommended for strengthening skeletal muscles?

• Sleeping all day

• Eating a balanced diet

• Drinking milk

• Exercise
