Knee Anatomy

Front

What is A?

Back

Quadriceps Muscles

Answer explanation

The correct answer is the Quadriceps Muscles, which are a group of four muscles located at the front of the thigh. They play a crucial role in knee extension and are essential for activities like walking and running.

Front

What bone is B? Options: Tibia, Fibula, Femur, Humerus

Back

Femur

Answer explanation

The femur is the longest bone in the body, located in the thigh. It connects the hip to the knee, distinguishing it from the tibia and fibula, which are in the lower leg, and the humerus, which is in the upper arm.

Front

What tissue is C? Options: Lateral Condyle, Articular Cartilage, Meniscus, Patellar Tendon

Back

Articular Cartilage

Answer explanation

C refers to Articular Cartilage, which is a smooth tissue covering the ends of bones at joints, allowing for smooth movement and reducing friction. The other options do not represent the tissue type indicated by C.

Front

What part of the Femur is D?

Back

Lateral Condyle

Answer explanation

The Lateral Condyle is located on the outer side of the femur's distal end, opposite the Medial Condyle. It is crucial for knee joint articulation, making it the correct answer for part D of the femur.

Front

What is J?

Back

Quadriceps Tendon

Answer explanation

J refers to the Quadriceps Tendon, which connects the quadriceps muscle to the patella. It plays a crucial role in knee extension, distinguishing it from the other options listed.

Front

What is L?

Back

Medial Collateral Ligament

Answer explanation

L refers to the Medial Collateral Ligament, which is a key ligament in the knee that provides stability and support. The other options are different ligaments, but L specifically denotes the Medial Collateral Ligament.

Front

What does "C" of ACL stand for?

Back

Cruciate

Answer explanation

The "C" in ACL stands for "Cruciate". The ACL, or Anterior Cruciate Ligament, is one of the key ligaments that help stabilize the knee joint, distinguishing it from other ligaments like collateral or connective.

Front

What does the "C" of MCL stand for?

Back

Collateral

Answer explanation

The "C" in MCL stands for Collateral. The MCL, or Medial Collateral Ligament, is a key ligament in the knee that provides stability and support, distinguishing it from other ligaments like the cruciate ligaments.

Front

A car crash is an example of what injury?

Back

PCL tear

Answer explanation

A car crash can lead to various knee injuries, including a PCL tear. The PCL (posterior cruciate ligament) is often injured in high-impact situations like car accidents, making it the correct choice here.

Front

What attaches to the tibial tuberosity?

Back

Patellar Tendon

Answer explanation

The patellar tendon attaches to the tibial tuberosity, connecting the patella to the tibia. This structure is crucial for knee extension, while the other options do not attach at this specific location.
