GCSE PE

Long bones

ao1: movement through levers: phalanges, metatarsals , metacarpals , clavicle humerus radius ulna femur tibia fibula

ao2: 🟥 For example, the femur allows you to kick and move the leg.

ao3 🟥 this is important because it allows the footballer to shoot and beat the goalkeeper to get the ball in the net

Short bones

ao1 bare the weight of the body e.g carpals and tarsals

ao2 🟥for example in a handstand the carpals will bare the way of the body

🟦for example, pushing off starting blocks in a 100m race

ao3 🟦this is important because you need to hold the body in a handstand with stability to get more points.

🟦 this is important because this allows the runner to get an explosive start to get an early advantage.

Flat bones

ao1: provide vital protection for organs

ao2: for example a footballer heading the ball

🟦 for example a rugby player taking a heavy impact to the chest.

ao3 : 🟥 this is important because the cranium protects the brain from damage and allows the player to head the ball and beat the Gk to score

🟦 this is important because the sternum shields the heart and allows them to continue playing.

Irregular bone

ao1: protect internal organs and provide attachment for muscles e.g. vertebrae and patella and coccyx

ao2:

🟥 for example a rugby player taking a heavy tackle to the back

🟦 for example a gymnast arching their back during a floor routine

ao3:

🟥 this is important because the vertebrae protect the spinal cord from damage and allow the player to absorb the impact and stay in possession of the ball.

🟦 this is important because the vertebrae support the spinal column and allow them to perform flexible twisting movements to score higher points.

Protection

ao1: protect vital organs from impact and injury e.g. ribs and sternum

ao2:

🟥 for example a ice hockey player taking a hard puck to the chest

ao3:

🟥 this is important because the ribs and sternum protect vital organs like the heart and lungs from traumatic fracture, allowing the player to safely stay in the game and defend their goal.

Mineral storage

ao1: store essential minerals to build bone strength and density

ao2:

🟥 for example a rugby player being heavily tackled by an opponent

ao3:

🟥 this is important because storing calcium and phosphorus increases bone density in major bones like the femur, preventing fractures during high-impact collisions so the athlete can continue playing.

Blood cells production

AO1: Bone marrow produces red blood cells, white blood cells, and platelets.

AO2: For example, a marathon runner taking part in a long-distance race.

AO3: This is important because the bone marrow (found in long bones like the femur) makes red blood cells to carry oxygen to the working muscles so they can keep releasing energy.

Muscle attachment / movement

ao1: act as rigid levers where muscles attach via tendons to create movement

ao2:

🟥 for example a footballer kicking a penalty kick into the top corner

ao3:

🟥 this is important because muscles attach to the femur and tibia via tendons to form levers, generating maximum force and speed in the leg to power the ball past the goalkeeper to score.

Joints

ao1: point where bones meet and are held by ligaments to allow movement

ao2:

🟥 for example a basketball player pivoting and throwing a pass to a teammate

ao3:

🟥 this is important because ligaments bind bones together at the elbow joint (humerus, radius, ulna), providing stability and smooth range of motion so the player can throw accurate passes without dislocating the joint.

Vetrebal column

Cervical (7)

Thoracic (12)

Lumbar (5)

Sacrum (5 fused)

Coccyx (4 fused)

Voluntary muscles

ao1: muscles attached to the skeleton under conscious control to create movement

ao2:

🟥 for example a sprinter driving out of the starting blocks in a 100m sprint

ao3:

🟥 this is important because voluntary muscles like the quadriceps and gastrocnemius contract consciously, pulling via tendons on long bones like the femur and tibia to produce explosive leg extension, giving the sprinter a fast start to win the race.

Involuntary muscles

ao1: muscles in internal organ and blood vessel walls that operate automatically without conscious control

ao2:

🟥 for example a road cyclist competing in a 3-hour endurance stage

ao3:

🟥 this is important because muscle in the walls of arteries automatically relaxes to widen blood vessels and redirect oxygen-rich blood flow straight to active leg muscles , maximizing oxygen delivery so the cyclist can sustain power output uphill, without having to think about it so you can focus on cycling

Cardiac muscle

ao1: muscles in internal organ and blood vessel walls that operate automatically without conscious control

ao2:

🟥 for example a road cyclist competing in a 3-hour endurance stage

ao3:

🟥 this is important because muscle in the walls of arteries automatically relaxes to widen blood vessels and redirect oxygen-rich blood flow straight to active leg muscles , maximizing oxygen delivery so the cyclist can sustain power output uphill, without having to think so you can focus on cycling

Type 11a muscle fibres

ao1: fast-contracting muscle fibres designed for high-intensity work over medium durations using both aerobic and anaerobic energy

ao2:

🟥 for example an 800m runner sprinting hard down the final straight of the track

ao3:

🟥 this is important because Type IIa fibres contract relatively quickly with relatively powerful force in muscles like the quadriceps while maintaining moderate resistance to fatigue, allowing the runner to sustain a fast speed to win the race.

Type I muscle fibres

ao1: slow-contracting muscle fibres designed for high aerobic endurance and resistance to fatigue

ao2:

🟥 for example a marathon runner pacing through a 26-mile race

ao3:

🟥 this is important because Type I fibres have a rich blood supply, allowing oxygen to be delivered efficiently to muscles like the gastrocnemius so the runner can sustain a steady pace without fatiguing.

Type 11x

ao1: very fast-contracting muscle fibres designed for maximum explosive power and force over short durations, fatiguing quickly

ao2:

🟥 for example a shot putter executing the final release of the shot.

ao3:

🟥 this is important because Type IIx fibres contract with a huge amount of power to generate explosive throwing force so the shot travels the maximum possible distance to win the competition.

Tendons

ao1: strong tissue that attaches muscle to bone to transfer force and create movement

ao2:

🟥 for example a high jumper driving upwards off the takeoff foot

ao3:

🟥 this is important because the Achilles tendon connects the gastrocnemius muscle to the heel pulling on the bone when the muscle contracts to produce explosive plantarflexion, propelling the athlete over the bar to clear a new height.

Ligaments

ao1: strong, elastic connective tissue that attaches bone to bone to stabilize joints and prevent dislocation

ao2:

🟥 for example a netballer landing firmly on one foot after jumping to catch a pass

ao3:

🟥 this is important because ligaments like the anterior cruciate ligament (ACL) connect the femur to the tibia at the knee joint, holding the bones together securely to absorb impact and prevent hyper-extension, allowing the player to maintain balance and prevent injury during sharp pivots.

Hinge joint

ao1: joint that allows movement in only one plane (flexion and extension) e.g. elbow and knee

ao2:

🟥 for example a footballer bending and extending their knee to strike a volley

ao3:

🟥 this is important because the hinge joint between the femur and tibia allows rapid flexion and extension created by the quadriceps and hamstrings, generating powerful leg speed to strike the ball cleanly and score.

Ball and socket joint

ao1: joint that allows movement in all direction/planes (e.g.) shoulder and hip

ao2:

🟥 for example a swimmer performing a butterfly stroke arm recovery through the air

ao3:

🟥 this is important because the ball and socket joint allows full 360-degree circumduction driven by the deltoids, to pull maximum water per stroke and win the race.

Condyloid

ao1: joint that allows movement in two planes e.g. wrist

ao2:

🟥 for example a basketball player flicking their wrist when taking a jump shot

ao3:

🟥 this is important because the condyloid joint connecting the radius and ulna to the carpals allows you to flick your wrist with accuracy to score a three-pointer.

Pivot

joint that allows rotation around a single axis e.g. neck (atlas and axis)

ao2:

🟥 for example a football goalkeeper turning their head to track a cross coming into the penalty area

ao3:

🟥 this is important because the pivot joint between the atlas and axis vertebrae allows rotational movement of the cranium, enabling the goalkeeper to maintain full visual awareness of attackers and make a save.
