In the lower extremity, the fibula articulates with which bone at its proximal end?

Tibia
Patella
Femur
Calcaneus

The correct answer is: Tibia

The proximal end of the fibula articulates with the tibia, forming a syndesmosis, which is a type of joint where two bones are connected by a ligament. This articulation is crucial for the stability of the lower leg and provides support for weight-bearing activities. The fibula primarily serves as a site for muscle attachment and plays a role in the overall function of the ankle joint, although it does not bear significant weight compared to the tibia. The other bones listed do not articulate with the fibula at its proximal end: the patella is a sesamoid bone that articulates with the femur, while the calcaneus is part of the foot and does not interact with the fibula at the proximal end. The femur, being a bone of the thigh, has its own distinct articulation with the patella and does not connect with the fibula in this area.
