Understanding Voluntary and Involuntary Muscular Movements

The video explains the difference between voluntary and involuntary muscular movements. Voluntary movements are controlled by the motor cortex and involve conscious control, such as typing. Involuntary movements occur automatically, controlled by the medulla oblongata, and include functions like breathing and heart rate. The video highlights the roles of smooth and cardiac muscles in involuntary actions and concludes with a summary of these concepts.

What is the primary function of the muscular system in humans?

• To digest food

• To enable movement

• To produce hormones

• To circulate blood

Which type of muscular movement is exemplified by typing?

• Involuntary

• Automatic

• Reflexive

• Voluntary

What type of muscles work automatically to keep you alive?

• Reflex muscles

• Involuntary muscles

• Voluntary muscles

• Skeletal muscles

What is the role of the peripheral nervous system in voluntary movements?

• To digest food

• To regulate heart rate

• To send signals from the brain to muscles

• To control involuntary muscles

Which part of the brain is involved in planning and executing voluntary movements?

• Brainstem

• Hypothalamus

• Motor cortex

• Cerebellum

What are the two major types of involuntary muscles?

• Skeletal and cardiac

• Smooth and cardiac

• Cardiac and reflexive

• Skeletal and smooth

Where can smooth muscles be found in the body?

• In the bones

• In the brain

• In the heart

• In the stomach and intestines

Which part of the brain controls involuntary movements like breathing and digestion?

• Cerebellum

• Medulla oblongata

• Cerebrum

• Thalamus

What is the main difference between voluntary and involuntary muscles?

• Voluntary muscles are automatic, involuntary muscles are controlled

• Both are controlled by the motor cortex

• Both are automatic

• Voluntary muscles are controlled, involuntary muscles are automatic

Which of the following is NOT a function of involuntary muscles?

• Heart rate regulation
