Take this free patella anatomy quiz to test your knowledge on the major structures on the patella bone. The patella bone is also known as the kneecap. This picture below is of the left patella bone, and it contains structures such as the base, apex, lateral and medial borders, surface for patellar ligament, facet for lateral condyle of femur, and the face for the medial condyle of the femur.

Patella Anatomy Quiz
1. The patella is classified as an irregular bone.
a. True
b. False
The answer is b, false. The patella bone is classified as a sesamoid bone, which is sometimes considered a subcategory of short bones. It is the largest sesamoid bone in the human skeleton.
2. The patella is part of which of the following?
a. Axial skeleton
b. Appendicular skeleton
c. The anatomical skeleton
d. The ossified skeleton
The answer is b, appendicular skeleton, which includes the bones of the upper and lower limbs, feet and hand bones, as well as the pelvic and pectoral girdle.
3. Identify the structure labeled as 1.
a. base
b. apex
c. lateral border
d. surface for patellar ligament
The answer is a, base. This is the superior portion of the patella that allows for the attachment of the quadriceps muscle.
4. Identify the structure labeled as 2.
a. Medial border
b. Lateral border
c. Apex
d. Surface for patellar ligament
The answer is b, lateral border. This is the left patella bone, so the lateral border is going to be on the right side, when looking at the anterior (front) view. If this were the right patella bone, it would be on the other side. Lateral is always going to be the side furthest from the body’s midline.
5. Identify the structure labeled as 3.
a. Medial border
b. Lateral border
c. Facet for medial condyle of femur
d. Apex
The answer is d, Apex. This is always going to point toward the foot, and it allows for the attachment of the patellar ligament.
6. Identify the structure labeled as 4.
a. Lateral border
b. Medial border
c. Apex
d. Facet for medial condyle of femur
The answer is b, medial border. Because this is the left patella bone, this is the side that is going to be closest to the body’s midline. If this were the right patella bone, this side would have been the lateral border.
7. Identify the structure labeled as 5.
a. Surface for patellar ligament
b. Apex
c. Facet for medial condyle of femur
d. Facet for lateral condyle of femur
The answer is c, facet for medial condyle of the femur. The smaller facet is going to be the medial condyle, and it has a sharper angle than the lateral facet.
8. Identify the structure labeled as 6.
a. Facet for medial condyle of femur
b. Apex
c. Facet for lateral condyle of femur
d. Surface for patellar ligament
The answer is c, facet for lateral condyle of femur. The lateral facet is the larger facet. When you look at the posterior view of the patella, you can tell which patella bone you’re looking at. If the larger lateral facet is on the left side, it is the left patella bone. If on the right, it’s the right patella bone.
9. Identify the structure labeled as 7.
a. Surface for patellar ligament
b. Facet for lateral condyle of femur
c. Facet for medial condyle of femur
d. Base of patella
The answer is a, the surface for the patellar ligament.
