Thoracic vertebraFacets on its body meet the heads of the ribs. The spinous process is long and slants downward.
Card 18 1
Lumbar vertebraThe largest kind of vertebra, with a large body. The vertebral foramen is a triangle.
Card 19 1
Cervical vertebraA hole in each transverse process marks it. The spinous process is short and forked, and the vertebral foramen is large and triangular.
Card 20 1
Hyoid boneA U-shaped bone with a body and four horns. Two are the greater horns and two the lesser horns.
Card 21 1
CalcaneusThe largest tarsal bone. It forms the heel and lies under the talus.
Card 22 1
TalusA body, a neck and a head. The trochlea on top of the body meets the tibia, and the talus rests on the calcaneus.
Card 23 1
CoccyxThe tailbone, usually four small fused vertebrae. It is the last part of the vertebral column.
Card 24 1
MetacarpalOne of five bones of the palm. Each has a base at the wrist end, a shaft and a head at the finger end.
How this list was compiled: The feature that tells each bone was checked on 2026-10-01 in at least two of these, and written in our own words: Henry Gray, Anatomy of the Human Body (1918, public domain), the section on each bone; TeachMeAnatomy, the page on each bone; and Wikipedia, Clavicle, Patella, Calcaneus, Talus bone, Coccyx, Hyoid bone, Rib, Axis and Metacarpal bones.

How it works
A lab practical lays single bones on a tray and asks for their names. This individual bone quiz does the same with drawings, from the femur to the hyoid: one bone, four names, pick one.

Long bones
Look at the ends. The femur has a head on a neck. The humerus has the trochlea and the capitulum at its elbow end. The radius has a small disc for a head, and the ulna a deep notch. The tibia ends in the inner ankle bump and the fibula in the outer one.
Vertebrae
The atlas is a ring with no body. The axis has the dens standing on its body. A cervical vertebra has a hole in each transverse process, a thoracic vertebra has rib facets and a long spinous process, and a lumbar vertebra is the largest.
Atlas or axis? The atlas has no body; the axis has the dens.
Tibia or fibula? The medial malleolus is on the tibia, the lateral one on the fibula.
Questions and answers
Is this a disarticulated bones quiz?
Yes. Every bone is drawn apart from the skeleton, as on a lab tray, and you name it from its shape. When the round ends the whole tray comes back with your answers written on it: a disarticulated skeleton labeled bone by bone.
How do you tell the radius from the ulna?
The radius has a small disc-shaped head at the elbow and a wide wrist end with the styloid process. The ulna has a deep notch at the elbow, between the olecranon and the coronoid process.
How do you tell the atlas from the axis?
The atlas, the first cervical vertebra, is a ring with no body and no spinous process. The axis, the second, has the dens: a peg of bone that stands up from its body.
How do you tell a thoracic vertebra from a lumbar vertebra?
A thoracic vertebra has facets on its body for the heads of the ribs and a long spinous process that slants downward. A lumbar vertebra is larger, with a large body and a triangular vertebral foramen.
