This lesson covers the identification and location of the major bones of the skeleton as required by the AQA GCSE PE specification (3.1.1.1 — Structure and Functions of the Musculoskeletal System). You need to be able to identify and locate each bone, understand where it sits within the skeleton, and relate its position to sporting movements.
The human skeleton contains 206 bones in adults, but for GCSE PE you are required to know 14 specific bones (or bone groups). Being able to identify these bones accurately is the foundation for understanding joints, movements, muscles, and sporting actions in later lessons.
The AQA specification requires you to know the following bones:
| Bone | Location | Description |
|---|---|---|
| Cranium | Head | The skull bones that enclose and protect the brain |
| Vertebrae | Spine / back | A column of 33 bones running from the skull to the pelvis |
| Scapula | Upper back / shoulder | A flat, triangular bone also known as the shoulder blade |
| Humerus | Upper arm | The long bone between the shoulder and the elbow |
| Ribs | Chest | 12 pairs of curved bones forming the ribcage |
| Sternum | Centre of the chest | The flat breastbone connecting the ribs at the front |
| Radius | Forearm (thumb side) | The shorter forearm bone on the lateral (thumb) side |
| Ulna | Forearm (little finger side) | The longer forearm bone on the medial (little finger) side |
| Pelvis | Hips | A large, basin-shaped bone supporting the spine and protecting organs |
| Femur | Upper leg / thigh | The longest and strongest bone in the body |
| Tibia | Lower leg (front / inner) | The shinbone — the larger of the two lower leg bones |
| Fibula | Lower leg (outer) | The thinner bone on the outside of the lower leg |
| Patella | Front of the knee | The kneecap — a small, flat, triangular bone |
| Talus | Ankle / foot | The ankle bone that connects the leg to the foot |
Exam Tip: You must be able to identify bones on a diagram as well as name them from a description. Practise labelling a blank skeleton diagram from memory — this is a common exam question format.
The skeleton is divided into two main parts. Understanding this division helps you organise the bones logically.

The axial skeleton forms the central axis of the body. It includes:
Cranium — the dome of the skull that surrounds the brain. It is made up of several fused bones and does not move. In sport, the cranium is at risk during contact activities such as rugby, boxing, and football (heading the ball).
Vertebrae — the vertebral column (spine) is made up of 33 vertebrae divided into five regions: cervical (7, in the neck), thoracic (12, in the upper back), lumbar (5, in the lower back), sacral (5, fused), and coccygeal (4, fused — the tailbone). The vertebrae protect the spinal cord and allow the trunk to flex, extend, and rotate.
Ribs — there are 12 pairs of ribs. The upper 7 pairs are "true ribs" attached directly to the sternum, the next 3 pairs are "false ribs" attached indirectly, and the bottom 2 pairs are "floating ribs" with no front attachment. Together they form the ribcage, which protects the heart and lungs.
Sternum — the flat breastbone at the front of the chest. It connects the ribs and provides attachment points for muscles. The sternum is important in CPR — chest compressions are applied directly over the sternum.
The appendicular skeleton includes the limbs, shoulder girdle, and pelvic girdle. These are the bones involved most directly in sporting movements.
Scapula — the shoulder blade is a flat, triangular bone on the upper back. It provides attachment points for many muscles including the deltoid, trapezius, and rotator cuff muscles. It moves with the shoulder during throwing, swimming, and racquet sports.
Humerus — the upper arm bone connecting the shoulder to the elbow. It forms the ball-and-socket joint at the shoulder and the hinge joint at the elbow. Throwing, batting, and serving in tennis all involve movement of the humerus.
Radius — the forearm bone on the thumb side (lateral side). It is shorter than the ulna and rotates around the ulna to allow the palm to face up (supination) or down (pronation).
Ulna — the forearm bone on the little finger side (medial side). It forms the main part of the hinge joint at the elbow. The bony point of your elbow (the olecranon process) is the top of the ulna.
Pelvis — a large, strong, basin-shaped bone at the base of the spine. It supports the weight of the upper body, protects the organs in the lower abdomen, and provides attachment for the powerful hip and thigh muscles. The pelvis connects to the femur at the hip joint.
Femur — the thigh bone and the longest, strongest bone in the body. It extends from the hip to the knee. The femur transmits body weight when standing, walking, and running. It is crucial in kicking, sprinting, and jumping.
Patella — the kneecap is a small, triangular sesamoid bone embedded within the tendon of the quadriceps muscle. It protects the front of the knee joint and acts as a lever, increasing the efficiency of the quadriceps when extending the leg.
Tibia — the shinbone is the larger of the two lower leg bones. It bears most of the body's weight below the knee and forms the knee joint above and the ankle joint below.
Fibula — the thinner bone on the outside of the lower leg. It does not bear much weight but provides attachment points for muscles and helps stabilise the ankle joint.
Talus — the ankle bone sits between the tibia/fibula above and the calcaneus (heel bone) below. It forms the ankle joint and is essential for all movements involving the foot — running, jumping, and changes of direction.
Exam Tip: A common way to remember which forearm bone is which: the Radius Rotates and is on the same side as your thumb. The Ulna is on the same side as your little finger — think "Ulna = Under" when the palm faces down.
Being able to link bones to sporting actions is essential for high marks. Here are some examples:
| Sporting Action | Key Bones Involved |
|---|---|
| Heading a football | Cranium, vertebrae |
| Throwing a javelin | Scapula, humerus, radius, ulna |
| Sprinting | Pelvis, femur, tibia, fibula, talus, patella |
| Performing a handstand | All upper and lower limb bones, vertebrae |
| Kicking a football | Femur, tibia, fibula, patella, talus |
| Catching a cricket ball | Humerus, radius, ulna |
| Sit-ups / core exercises | Vertebrae, ribs, pelvis |
| Goalkeeper diving | Scapula, humerus, pelvis, femur |
In the exam, you will be given a diagram of the skeleton and asked to label specific bones. Here is a systematic approach:
