Location of major bones

Welcome to the Human Framework!

Ever wondered why you don't just collapse into a puddle on the floor? It is all thanks to your skeletal system! In this section, we are going to learn the names and locations of the 19 major bones you need to know for your OCR GCSE PE exam. Think of this as learning the "chassis" of a car—once you know where the parts are, understanding how the body moves becomes much easier.

Don't worry if some of the names sound like a different language at first. By the end of this page, you’ll have some clever tricks to remember exactly where they go!

1. The Central Command: Head and Torso

The bones in the middle of your body protect your most vital organs, like your brain, heart, and lungs.

Cranium: This is your skull. Its main job is to protect your brain.
Analogy: Think of it as a natural, built-in crash helmet.

Vertebrae: These are the small bones that make up your spine (your backbone). They are stacked on top of each other to let you bend and twist.
Quick Review: The vertebrae protect your spinal cord!

Ribs: These curved bones form a "cage" around your chest to protect your heart and lungs.

Sternum: Often called the breastbone. It sits right in the middle of your chest, and your ribs attach to it.
Memory Aid: "Sternum" sounds like "Stern" (serious). A captain stands at the front of a ship, just like this bone is at the front of your chest.

Key Takeaway:

The Cranium, Vertebrae, Ribs, and Sternum form the central protective core of your body.

2. The Upper Body: Shoulders and Arms

These bones allow for a massive range of movement, from throwing a javelin to swimming front crawl.

Clavicle: This is your collarbone. It connects your arm to your body at the front.
Scapula: Your shoulder blade. It’s the flat, triangular bone at the back of your shoulder.

Humerus: The long bone in your upper arm.
Mnemonic: It sounds like "humorous" (funny). That’s why we call it the "funny bone" when you knock your elbow!

Radius and Ulna: These are the two bones in your forearm (between your elbow and wrist).
How to tell them apart: The Radius is on the thumb side. (Think: "The Radius radiates from the thumb"). The Ulna is on the pinky-finger side.

Carpals, Metacarpals, and Phalanges:
• Carpals: The small bones in your wrist. (Think: You use your wrist to steer a Car).
• Metacarpals: The bones in the palm of your hand.
• Phalanges: Your fingers (and also your toes!).

Key Takeaway:

In the arm, remember the Humerus is at the top, and the Radius always follows your thumb!

3. The Lower Body: Hips and Legs

These are some of the strongest bones in the body because they have to support your entire weight when you run or jump.

Pelvis: Your hip bone. It’s shaped like a bowl and connects your spine to your legs.

Femur: Your thigh bone.
Did you know? The Femur is the longest, strongest, and heaviest bone in the human body!

Patella: This is your kneecap. It’s a small, circular bone that sits in front of the knee joint.

Tibia and Fibula: The two bones in your lower leg.
How to tell them apart:
• The Tibia is the thick "Shin Bone" at the front. (Think: Tibia is Thick).
• The Fibula is the thinner bone on the outside. (Think: A "Fib" is a little lie, and the Fibula is a little bone).

Tarsals, Metatarsals, and Phalanges:
• Tarsals: The bones in your ankle. (Think: Tarsals for Toes).
• Metatarsals: The bones in the main part of your foot.
• Phalanges: Your toes.

Key Takeaway:

The Femur is the big thigh bone, the Tibia is your shin, and the Phalanges are found in both your hands and your feet.

Quick Check: Common Mistakes to Avoid

• Mixing up Radius and Ulna: Always look for the thumb! The Radius is the one on the thumb side.
• Mixing up Carpals and Tarsals: Remember Carpals are for the Car (hands), Tarsals are for Trekking (feet).
• Spelling: Make sure you can spell Phalanges (it's a tricky one!) and Vertebrae.
