Question 2 • 2026-2027 EDGE Human Anatomy and Physiology A

Which features differentiate the knee joint from most other joints in the body? Check all of the boxes that apply.

Answer
A
The knee joint is an ellipsoidal joint.
B
The knee joint contains a cartilaginous pad.
C
The knee joint is made of multiple joints.
D
The knee joint permits a wide range of motion.

Explanation

The knee contains crescent-shaped pads of fibrocartilage called menisci, which help cushion and stabilize the joint. It also consists of multiple articulations: the tibiofemoral joint and the patellofemoral joint. The knee is a modified hinge joint, not an ellipsoidal joint, and its movement is more limited than that of joints with a wide range of motion.
