Frontal bone (forehead)One bone that forms the forehead. It also forms the upper rim of each eye socket, and meets the two parietal bones at the coronal suture.
Parietal boneA pair, right and left. They form most of the roof and upper sides of the skull and meet each other along the sagittal suture on top of the head.
Temporal boneA pair, each forming the skull's lower side around the ear. Each houses the three tiny middle ear bones. The bump behind the earlobe is its mastoid process.
Occipital boneOne bone at the back and base of the skull. The spinal cord passes through its large opening, the foramen magnum.
Nasal boneA pair of small bones lying side by side. Together they form the bridge of the nose; the rest of the nose is cartilage, which a skeleton does not show.
Zygomatic bone (cheekbone)A pair, each forming the prominence of the cheek. Each also forms part of the outer rim of the eye socket, and sends a bar back toward the temporal bone.
Maxilla (upper jaw)A pair that join in the midline. Together they form the upper jaw, hold the upper teeth and make up most of the hard palate.
Mandible (lower jaw)One bone, and the only bone of the skull that moves. It holds the lower teeth.
Spine and rib cage 7
Cervical vertebrae (neck)Seven vertebrae, C1 to C7. C1 is the atlas, which carries the skull, and C2 is the axis, the pivot it turns on.
Thoracic vertebrae (upper back)Twelve vertebrae, T1 to T12. Each one carries a pair of ribs.
Lumbar vertebrae (lower back)Five vertebrae, L1 to L5. They are the largest in the column because they carry the most body weight.
SacrumFive vertebrae that fuse into one triangular bone. They start fusing at about age 20. It joins the two hip bones at the sacroiliac joints.
Coccyx (tailbone)Three to five small vertebrae fused together, most often four. It is the lowest part of the vertebral column.
Sternum (breastbone)One flat bone in three parts. From top to bottom: manubrium, body and xiphoid process. The clavicles and the first seven pairs of ribs attach to it.
RibsTwelve pairs, 24 bones. Pairs 1 to 7 are true ribs, pairs 8 to 12 are false ribs, and the last two pairs, 11 and 12, are floating ribs.
Shoulder and arm 8
Clavicle (collarbone)The only long bone that lies horizontally. It runs from the manubrium of the sternum to the acromion of the scapula. A pair.
Scapula (shoulder blade)A pair of flat, roughly triangular bones. Each links the humerus to the clavicle; the ridge across its back is the spine, which ends in the acromion at the top of the shoulder.
Humerus (upper arm bone)A pair. The humerus is the only bone of the upper arm. Its rounded head fits the shallow socket of the scapula, and its lower end meets the radius and ulna at the elbow.
RadiusA pair. The radius is the forearm bone on the thumb side. It is slim at the elbow and broad at the wrist, where it meets the carpals.
UlnaA pair. The ulna is the forearm bone on the little-finger side. Its upper end, the olecranon, is the point of the elbow.
Carpals (wrist bones)Eight small bones in each wrist, in two rows of four. They are scaphoid, lunate, triquetrum and pisiform, then trapezium, trapezoid, capitate and hamate.
Metacarpals (palm bones)Five in each hand, numbered 1 to 5 starting at the thumb. Their rounded far ends are the knuckles you see when you make a fist.
Phalanges of the hand (finger bones)Fourteen in each hand. Each finger has a proximal, a middle and a distal phalanx, and the thumb has only two.
Hip and leg 12
IliumThe broad upper part of the hip bone. Its curved top edge is the iliac crest. Ilium, ischium and pubis fuse into one hip bone by the end of puberty.
PubisThe front part of the hip bone. The right and left pubic bones meet in the midline at a joint called the pubic symphysis.
IschiumThe lower back part of the hip bone. Its thick ischial tuberosity, often called the sit bone, carries your weight when you sit.
Femur (thigh bone)The only bone of the thigh and the longest in the body. Its ball-shaped head fits the socket of the hip bone. A pair.
Patella (kneecap)The largest sesamoid bone, a bone that forms inside a tendon. Here it is the tendon of the quadriceps. It starts turning to bone at about age three. A pair.
Tibia (shinbone)The larger, inner bone of the lower leg. It is the one that bears the weight, and the second largest bone after the femur. A pair.
Fibula (calf bone)The most slender of the long bones, carrying little weight. Its lower end, the lateral malleolus, is the bump on the outside of the ankle. A pair.
Talus (ankle bone)One of the seven tarsals, and the second largest. It passes the whole weight of the body from the leg to the foot, and no muscle attaches to it.
TarsalsSeven in each foot. They are talus, calcaneus, navicular, cuboid and the medial, intermediate and lateral cuneiforms.
Calcaneus (heel bone)The largest tarsal and the largest bone of the foot. It forms the heel, sits under the talus, and the Achilles tendon attaches to the back of it.
MetatarsalsFive in each foot, numbered 1 to 5 from the big toe. The first is the shortest and the second is the longest. They match the metacarpals of the hand.
Phalanges of the foot (toe bones)Fourteen in each foot, the same count as in the hand. The big toe has two phalanges and each of the other four toes has three.

The drawing: Drawn for this site, 2026-09-20. Proportions and bone shapes were checked by eye against three public-domain pictures on Wikimedia Commons: Gray188.png (side view of the skull from Gray, Anatomy of the Human Body, 1918), Human_skeleton_front_-_no_labels.svg and Human_skeleton_back_en.svg (Mariana Ruiz Villarreal, released into the public domain), and against the descriptions of the wrist and ankle bones in the English Wikipedia articles Carpal bones and Tarsus (skeleton). Nothing was traced or copied, and the numbers and labels are our own. Licence: own work
How it works
This bones of the body quiz starts from an unlabeled skeleton diagram. It shows a front view, a back view and a larger side view of the skull, with 35 numbered bones. Tap or click the bone the question names, or switch to Name it and name the one that lights up. When a round ends, the main button replays your misses. It prints blank or labeled.
Read the full guide
Bone labeling in three modes
Find it shows a name, such as patella (kneecap), and you tap its numbered ring. A wrong tap tells you which bone you did tap, shows the right one and counts as a miss. Name it lights one bone. Pick from 4 choices, or choose Type it. Typing forgives capitals, plurals and one slipped letter, and everyday names count. Study writes every name on the drawing; tap a bone for its detail line.
Narrow the skeleton to one region
The sets under Start from cut a round down to the skull (8 bones), the spine and rib cage (7), the shoulder and arm (8) or the hip and leg (12), and the drawing zooms to match. For an anatomy bone labeling quiz by region, clear one group before adding the next. As in textbooks, the clavicle and scapula count with the arm.
Where missed bones go
A finished round shows a line like 9 of 12, and the main button becomes Practise the 3 you missed for one round of only those bones. Share score copies a link with your score and time, and no name. This is a quiz, not a bone labeling game: rounds and a shrinking missed list, no lives or levels.
Start with the six long bones of the limbs: humerus, radius, ulna, femur, tibia and fibula. Smaller bones are easier to place once these are fixed.
The radius ends at the thumb. With palms forward, as drawn here, it is the outer forearm bone and the ulna the inner one.
The tibia is the thick inner bone you can feel as your shin. The fibula is the thin one on the outside.
Carpals are in the wrist and tarsals in the foot. Metacarpals and metatarsals follow the same pattern, and hands and feet both end in phalanges.
Run it as a skeletal anatomy quiz in two passes: Find it until nothing is missed, then Name it set to Type it.
Questions and answers
Is this an all 206 bones quiz?
Not bone by bone. A 206 bones quiz on one drawing would need rings too small to tap, so the 35 parts here stand for 190 of the 206 bones in the usual adult count. Ribs is one part for 24 bones. Left out are the hyoid, the six middle ear bones and nine small bones deep in the skull.
Why is there no part called pelvis?
The pelvis is a ring of several bones: two hip bones plus the sacrum and coccyx. Each hip bone is an ilium, an ischium and a pubis that fuse by the end of puberty. A first course asks for those five names, so they are the parts here.
Which names does this skeletal system labeling quiz accept?
Labels give the standard anatomical name with the everyday name in brackets, as in clavicle (collarbone), and typed answers accept either. These are the names bone labeling anatomy handouts use in a first course. They were checked against Wikipedia's list of bones of the human skeleton and an open anatomy textbook on the date at the bottom of this page.
Is there a label the skeleton worksheet pdf?
Yes. Print blank gives an unlabeled blank skeleton diagram with rings numbered 1 to 35, a name and date line, and an answer line for each number. Print labelled adds the names. For a blank skeleton diagram to label pdf, choose Save as PDF in the print dialog.
Is this enough for an anatomy and physiology bones quiz?
It covers the whole-skeleton names a first anatomy and physiology course expects. Lab practicals often ask for markings on single bones, such as the olecranon of the ulna. For that depth, use the single-region pages listed below: the skull, hand, foot and vertebrae each have a larger drawing.
Where does the skeleton drawing come from?
It is an original line drawing made for this site, with proportions checked against public-domain anatomical plates. No artwork or labels were copied from anywhere else. The side view of the skull is there because those bones are too small to tap on a standing figure.
