Location of major bones
This topic covers the structure and function of the skeletal system, including the location of major bones, the functions of the skeleton, types of synovial joints, and the movements possible at hinge and ball and socket joints.
Topic Overview
The human skeleton is a complex framework of bones that provides structure, protection, and movement. In OCR GCSE Physical Education, you need to know the location of major bones, including the cranium, clavicle, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges, sternum, ribs, vertebrae, pelvis, femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges. Understanding where these bones are located is essential for analysing movement, identifying injuries, and explaining how the skeletal system works with muscles to produce motion.
This topic forms the foundation for more advanced concepts like joint types, muscle attachments, and lever systems. For example, knowing the humerus is in the upper arm helps you understand how the biceps and triceps work at the elbow. Similarly, locating the femur in the thigh is key to explaining knee and hip movements. Mastery of bone locations also supports your understanding of sports injuries, such as a fractured radius from a fall or a dislocated shoulder involving the scapula and humerus.
In exams, you may be asked to label diagrams, describe the location of bones, or explain their functions. A strong grasp of bone locations will help you answer these questions accurately and confidently. Use mnemonics, flashcards, or palpation (feeling your own bones) to reinforce your learning. Remember, the skeleton isn't just a list of names—it's a dynamic system that enables all physical activity.
Key Concepts
Core ideas you must understand for this topic
- →The axial skeleton includes the skull (cranium), vertebral column (vertebrae), ribs, and sternum. It protects vital organs like the brain, spinal cord, heart, and lungs.
- →The appendicular skeleton includes the limbs and girdles: the pectoral girdle (clavicle and scapula) attaches the arms, and the pelvic girdle (pelvis) attaches the legs.
- →Major bones of the upper limb: humerus (upper arm), radius (thumb side of forearm), ulna (little finger side), carpals (wrist), metacarpals (palm), and phalanges (fingers).
- →Major bones of the lower limb: femur (thigh), patella (kneecap), tibia (shin bone, front of lower leg), fibula (thin bone beside tibia), tarsals (ankle), metatarsals (foot), and phalanges (toes).
- →Bones are named based on their location and shape; for example, the scapula is a flat bone on the posterior side of the shoulder, and the pelvis is a large, irregular bone at the base of the spine.

Examiner Tips
Expert advice for maximising your marks
- 💡Use specific sporting examples to illustrate how the skeleton allows for movement or protection.
- 💡Ensure you can correctly identify the articulating bones for the four key joints: knee, elbow, shoulder, and hip.
- 💡Practice linking joint types to the specific movements they allow.
- 💡When labelling diagrams, always use the correct anatomical terms (e.g., 'cranium' not 'skull' if the specification uses 'cranium'). Be precise with left/right orientation if the diagram shows a specific side.
- 💡To remember bone locations, use the 'thumb rule': the radius is on the thumb side of the forearm, and the tibia is on the big toe side of the lower leg. This helps avoid confusion in exams.
- 💡Practice drawing simple stick figures and labelling the major bones. This active recall technique is more effective than passive reading and helps you visualise locations quickly under time pressure.
Common Mistakes
Pitfalls to avoid in your exam answers
- Confusing articulating bones at specific joints.
- Failing to apply skeletal functions to specific sporting examples.
- Incorrectly identifying the type of movement occurring at a joint during a specific phase of a sporting action.
- Misconception: The radius and ulna are in the upper arm. Correction: The radius and ulna are in the forearm; the humerus is the single bone in the upper arm.
- Misconception: The patella is part of the lower leg. Correction: The patella is a sesamoid bone embedded in the quadriceps tendon, located in front of the knee joint, not in the lower leg.
- Misconception: The clavicle and scapula are part of the axial skeleton. Correction: They are part of the appendicular skeleton, forming the pectoral girdle that connects the upper limbs to the axial skeleton.
