Which of the following is a function of muscles in the human body?
To digest food
To maintain posture
To produce hormones
To filter blood
What is the main difference between voluntary and involuntary muscle contraction?
Voluntary muscles contract without your control, involuntary muscles require conscious effort
Voluntary muscles are only found in the heart, involuntary muscles are found in the arms
Voluntary muscle contraction is under your conscious control, involuntary muscle contraction occurs automatically
Voluntary muscles are not found in the body
Label the pictures by muscle type: Which type of muscle is shown in the third image (striped, branched cells)?
Smooth muscle
Skeletal muscle
Cardiac muscle
Connective tissue
Explain why cardiac muscle never fatigues and discuss the importance of this characteristic for the function of the heart.
Because it contains many mitochondria, ensuring a constant energy supply, which is essential for continuous heart function
Because it is voluntary and can rest when needed, which helps the heart relax
Because it is made of bone tissue, which is very strong
Because it only works when you are awake, allowing it to rest at night
Where can smooth muscle be found in the human body?
Attached to bones
In the heart
In the walls of internal organs
In the skin
What is the primary function of tendons in the muscular system?
To connect muscles to other muscles
To connect bones to bones
To connect muscles to bones
To produce movement in the heart
Why is it important that skeletal muscles are paired?
So they can contract at the same time
So one can contract while the other relaxes
So they can both push bones
So they can both pull bones
Arrange the following sequence of events that lead to the movement of muscles in the correct order: 1. The brain sends an electrical signal to the nerves. 2. The nerves release neurotransmitters. 3. The neurotransmitters signal muscle contraction.
1, 2, 3
2, 1, 3
3, 2, 1
1, 3, 2
Which of the following best describes the roles of actin and myosin in muscle contraction?
Actin and myosin are both thick filaments that relax muscles.
Actin is a thin filament and myosin is a thick filament; they interact to contract muscles.
Actin is a thick filament and myosin is a thin filament; they relax muscles.
Both actin and myosin are thin filaments that contract muscles.
What is the primary energy source used by muscle fibers during contraction?
Oxygen
Lactic acid
Glucose
ATP
Which statement best explains how lactic acid contributes to muscle fatigue?
Lactic acid provides more energy for muscle contraction.
Lactic acid builds up in muscles, causing soreness and fatigue.
Lactic acid cools down the muscles after exercise.
Lactic acid increases oxygen supply to the muscles.
During the wall sit activity, why might a person be unable to sit longer, and what sensations might they feel?
Because of muscle fatigue, they may feel burning or soreness in their leg muscles.
Because of dehydration, they may feel thirsty.
Because of hunger, they may feel stomach pain.
Because of excitement, they may feel energetic.
If your hypothesis about the number of clothespin squeezes in each round was incorrect, what would be a logical reason based on muscle physiology?
Muscle fibers get stronger with each round.
Muscle fatigue increases with repeated activity, reducing the number of squeezes.
The number of squeezes is always the same regardless of fatigue.
Lactic acid decreases muscle fatigue, increasing performance.
If you were to label the muscle responsible for arm flexion, which choice from A-K would you select?
Triceps
Biceps
Gluteus maximus
Gastrocnemius
When a muscle contracts, it ____________
gets longer
gets shorter
gets thinner
grows hair
