Musculoskeletal Basics
What are the two main parts of the skeletal system?
Answer: Axial and appendicular skeletons
What are the three types of muscles in the human body?
Answer: Skeletal, smooth, and cardiac
What is the main function of the cardiorespiratory system?
Answer: To deliver oxygen and remove carbon dioxide from the body
Which two systems work together to allow movement?
Answer: The muscular and skeletal systems
What is Mr Acocks favourite show
The Bold & Beautiful on a wednesday night
Name one function of the skeletal system other than movement.
Answer: Protection, support, storage of minerals, or blood cell production
What term describes the muscle that contracts to cause movement?
Answer: The agonist
Name the two upper chambers of the heart.
Answer: The left and right atria
How does the cardiorespiratory system support muscular performance during exercise?
Answer: By delivering oxygen and removing carbon dioxide to/from muscles
What's Mr Acock's favourite sport
Surfing
What type of joint allows movement in one direction only, like the elbow?
Answer: Hinge joint
During a bicep curl, which muscle acts as the antagonist?
Answer: The triceps
What is the correct order of airflow through the respiratory system?
Answer: Nose → Trachea → Bronchi → Bronchioles → Alveoli
What happens to heart rate and breathing rate during physical activity, and why?
Answer: They both increase to supply more oxygen and remove carbon dioxide faster
Whats Mr Acocks actual favourite show
The summer i turned pretty (makes his gf watch it too)
Explain the difference between ligaments and tendons.
Answer: Ligaments connect bone to bone; tendons connect muscle to bone.
Define the difference between isotonic and isometric muscle contractions.
Answer: Isotonic involves movement and muscle length change; isometric involves no movement but tension develops.
Explain how gas exchange occurs in the alveoli.
Answer: Oxygen diffuses from the alveoli into the blood; carbon dioxide diffuses from the blood into the alveoli.
Describe how the musculoskeletal and cardiorespiratory systems interact during endurance training.
Answer: Muscles use oxygen delivered by the cardiorespiratory system; the heart and lungs adapt to become more efficient at supplying oxygen and removing waste products.
What's Mr Acock's favourite thing in the world
Himself ....
Describe how the skeletal system supports efficient movement in sport.
Answer: It provides a rigid framework for muscle attachment, allows leverage through joints, and protects internal organs during motion.
Explain how muscle fatigue occurs and how it can be delayed.
Answer: Muscle fatigue occurs when energy stores are depleted and lactic acid builds up; it can be delayed through aerobic conditioning and active recovery.
Define Gaseous Exchange
Gaseous exchange is the movement of gases (oxygen and carbon dioxide) from areas of high concentration to areas of low concentration.
Explain how fatigue in one body system can affect performance in another during exercise.
Answer: If the cardiorespiratory system can’t deliver enough oxygen, muscles rely on anaerobic energy, leading to faster fatigue and reduced movement efficiency.
What sport did Mr Acocks give up recently so he could spend more time with his gf?
Cricket
