Each numbered ring is a button. Use the arrow keys to move between them and Enter to choose. Names are read out in Study, and once a ligament is answered.
Anterior cruciate ligament (ACL)(connection: the femur and the tibia)From the front of the tibia, up and back to the femur. The two cruciate ligaments cross each other, which is what their name means.
Posterior cruciate ligament (PCL)(connection: the femur and the tibia)From the back of the tibia, up and forward to the femur. It crosses the anterior cruciate ligament inside the joint.
Medial collateral ligament (MCL)(connection: the femur and the tibia)A wide, flat band on the inner side of the knee. It runs from the femur down to the tibia.
Lateral collateral ligament (LCL)(connection: the femur and the fibula)A round cord on the outer side of the knee. It runs from the femur down to the head of the fibula.
Transverse ligament of the knee(connection: the two menisci of the knee)A band between the front ends of the two menisci. It joins no bone to another.
Ankle, outer side 3
Anterior talofibular ligament(connection: the fibula and the talus)From the lateral malleolus of the fibula forward to the talus. It is one of three ligaments on the outer side of the ankle.
Posterior talofibular ligament(connection: the fibula and the talus)From the lateral malleolus of the fibula back to the talus. The lateral malleolus is the knob at the lower end of the fibula.
Calcaneofibular ligament(connection: the fibula and the calcaneus)From the lateral malleolus of the fibula down to the calcaneus. The calcaneus is the heel bone.
Hip, from the front 2
Iliofemoral ligament(connection: the ilium and the femur)From the ilium to the femur, across the front of the hip. It is very strong and shaped like a Y upside down.
Pubofemoral ligament(connection: the pubis and the femur)Runs from the pubis to the femur, low on the front. It strengthens the front and underside of the capsule.
Shoulder, from the front 6
Glenohumeral ligaments(connection: the scapula and the humerus)Three bands from the rim of the socket to the humerus. The socket is the scapula's glenoid cavity.
Coracohumeral ligament(connection: the scapula and the humerus)From the scapula's coracoid process to the humerus. It ends on the greater tubercle and strengthens the top of the capsule.
Coracoacromial ligament(connection: two parts of the scapula)From the coracoid process to the acromion, both on the scapula. With them it forms an arch over the head of the humerus.
Acromioclavicular ligament(connection: the scapula and the clavicle)From the acromion of the scapula to the end of the clavicle. It covers the top of the small joint between them.
Coracoclavicular ligament(connection: the scapula and the clavicle)From the scapula's coracoid process up to the clavicle. It has two parts, the conoid and the trapezoid ligaments.
Transverse humeral ligament(connection: the two tubercles of the humerus)From lesser tubercle to greater tubercle of the humerus. It bridges the groove between them.
Elbow, from the front 2
Annular ligament(connection: the radius and the ulna)A ring of ligament around the head of the radius. It holds the radius against the ulna while the forearm turns.
Radial collateral ligament(connection: the humerus and the annular ligament)From the humerus's lateral epicondyle down into the annular ligament. It lies on the outer side of the elbow.
Elbow, inner side 2
Ulnar collateral ligament, anterior band(connection: the humerus and the ulna)From the humerus's medial epicondyle to the coronoid process. It is the front part of the ulnar collateral ligament, and the coronoid process is part of the ulna.
Ulnar collateral ligament, posterior band(connection: the humerus and the ulna)From the humerus's medial epicondyle back to the olecranon. It is the back part of the ulnar collateral ligament, and the olecranon is part of the ulna.

How it works
This anatomy ligaments quiz lights one ligament on a drawing of a knee, ankle, hip, shoulder or elbow. Name it, then pick what it connects: most often two bones.
Read the full guide
Two answers for every ligament
A ligament lights on one of six drawings. Name it, and a second question asks what it connects. A question counts only when both answers are right. The first round asks the ten ligaments of the knee, ankle and hip; the next asks the ten of the shoulder and elbow.
What a ligament's name tells you
Many names are the two ends put together. The calcaneofibular ligament runs from the fibula to the calcaneus, the heel bone; the coracoclavicular from the scapula's coracoid process to the clavicle. Others are named for shape or place: cruciate means crossed, the annular ligament is a ring, and collateral ligaments lie at the sides of a joint.
Iliofemoral and pubofemoral: the first half of each name is the part of the hip bone where the ligament starts.
The knee is drawn without its kneecap, so the two crossed ligaments show in the gap between the bones.
Questions and answers
What is a ligament?
A ligament is a band of fibrous connective tissue that attaches one bone to another, usually at a joint. Most of the ligaments in this quiz do that; a few connect two parts of one bone, or two pads of cartilage.
What is the difference between the ACL and the PCL?
Both run between the tibia and the femur and cross inside the knee. The anterior cruciate ligament starts at the front of the tibia and runs up and back. The posterior starts at the back and runs up and forward.
Which ligaments join the scapula to the clavicle?
Two. The acromioclavicular ligament joins the acromion to the outer end of the clavicle. The coracoclavicular ligament, in two parts called conoid and trapezoid, runs from the coracoid process up to the clavicle.
Is there a human skeleton diagram with ligaments?
Not on one drawing here. On a whole skeleton the ligaments would be too small to tap, so they are drawn joint by joint: knee, ankle, hip, shoulder and elbow. The joints quiz rings the joints themselves on four figures of the skeleton.
How many ligaments does the quiz ask?
Twenty: five of the knee, three on the outer side of the ankle, two of the hip, six of the shoulder and four of the elbow. Each joint's own page asks the rest of its parts.
