Start here: 6 main bones 6

  1. Clavicle (collarbone) The collarbone. With the scapula it makes the shoulder girdle. The girdle joins the arm to the trunk.
  2. Scapula (shoulder blade) The shoulder blade, the other bone of the shoulder girdle. It lies behind the ribs.
  3. Humerus The bone of the upper arm, from the shoulder to the elbow.
  4. Hip bone (os coxae) Three fused parts: ilium, ischium and pubis. The two hip bones make the pelvic girdle with the sacrum and coccyx.
  5. Femur (thigh bone) The thigh bone, from the hip bone to the knee.
  6. Tibia (shinbone) The larger lower leg bone, the shinbone, on the inner side.

Arm and forearm 2

  1. Radius The forearm bone on the thumb side. It runs from the outer side of the elbow to the wrist.
  2. Ulna The forearm bone parallel to the radius on the little finger side. It is the longer of the two.

Wrist and hand 3

  1. Carpals (wrist bones) The 8 small bones of each wrist.
  2. Metacarpals The 5 bones of each palm, one for each finger.
  3. Phalanges of the hand The 14 bones of each hand's fingers. Two in the thumb, three in each finger.

Thigh and leg 2

  1. Patella (kneecap) The kneecap, a flat, rounded bone. It covers the front of the knee joint.
  2. Fibula The slender calf bone on the outer side of the tibia. Its lower end forms the outer part of the ankle.

Ankle and foot 3

  1. Tarsals (ankle bones) The 7 bones of each ankle and back of the foot.
  2. Metatarsals The 5 bones of each foot, one for each toe.
  3. Phalanges of the foot The 14 bones of each foot's toes. Two in the big toe, three in each other toe.

How this list was compiled: Read 2026-09-27. (1) Wikipedia, Appendicular skeleton, https://en.wikipedia.org/wiki/Appendicular_skeleton : 126 of the body's 206 bones in six regions: the shoulder girdle (clavicle and scapula each side), arms and forearms (humerus, ulna, radius), hands and wrists (16 carpals, 10 metacarpals, 28 phalanges), the pelvis (two hip bones, each a fusion of ilium, ischium and pubis), thighs and legs (femur, patella, tibia, fibula), feet and ankles (14 tarsals, 10 metatarsals, 28 phalanges). Wikipedia, Radius (bone): from the lateral side of the elbow to the thumb side of the wrist, parallel to the ulna, which is longer. Fibula: the calf bone on the lateral side of the tibia, the smaller, forming the lateral part of the ankle. Patella: the kneecap, a flat rounded bone covering the front of the knee joint. Hip bone: ilium, ischium and pubis; the two hip bones with the sacrum and coccyx form the pelvic girdle. (2) OpenStax, Anatomy and Physiology 2e, 7.1 Divisions of the Skeletal System, https://openstax.org/books/anatomy-and-physiology-2e/pages/7-1-divisions-of-the-skeletal-system : the appendicular skeleton includes all bones of the upper and lower limbs plus the bones that attach each limb to the axial skeleton, 126 bones in an adult.

How it works

Find each bone of the appendicular skeleton on a whole skeleton, palms forward, with the axial skeleton faint behind. Start with the 6 main bones, then the girdles, the arm and hand, the leg and foot.

Read the full guide

126 of 206 bones

The appendicular skeleton is the bones of the limbs and the girdles that join them to the trunk: the clavicle and scapula at the shoulder, the hip bones at the pelvis. Most of its 126 bones are in the hands and feet, 54 and 52.

Which side is which

The skeleton stands palms forward, so the radius lies on the thumb side, the ulna on the little finger side, and the thin fibula on the outer side of each tibia.

  • Pair the limbs: humerus and femur, radius and ulna with tibia and fibula, carpals with tarsals, metacarpals with metatarsals, and phalanges in both.

Questions and answers

What bones are in the appendicular skeleton?

The shoulder girdle (clavicle, scapula), the arm, forearm, wrist and hand bones, the hip bones of the pelvic girdle, and the thigh, knee, leg, ankle and foot bones: 126 bones in all.

What is the difference between the axial and appendicular skeleton?

The axial skeleton is the head and trunk: skull, spine, ribs and sternum, 80 bones. The appendicular skeleton is the limbs and the girdles that attach them, 126 bones.

Is the pelvis part of the appendicular skeleton?

The two hip bones are, as the pelvic girdle that attaches the legs. The sacrum and coccyx, which complete the pelvis, belong to the axial skeleton.
