Textbook Question

The fibula:
(a) Forms an important part of the knee joint
(b) Articulates with the femur
(c) Helps to bear the weight of the body
(d) Provides lateral stability to the ankle
(e) Does a and b

Verified step by step guidance

Step 1: Begin by identifying the anatomical location and function of the fibula. The fibula is the smaller of the two bones in the lower leg, located lateral to the tibia.

Step 2: Understand the role of the fibula in the body. It primarily provides structural support and stability to the ankle and lower leg, but it does not bear significant weight as the tibia does.

Step 3: Analyze the options provided in the question. Option (a) suggests the fibula forms part of the knee joint, but anatomically, the fibula does not directly contribute to the knee joint structure. Option (b) states it articulates with the femur, which is incorrect because the fibula does not articulate with the femur.

Step 4: Evaluate option (c), which states the fibula helps bear the weight of the body. This is incorrect because the tibia is the primary weight-bearing bone in the lower leg, not the fibula. Option (d) states the fibula provides lateral stability to the ankle, which is correct as the fibula plays a key role in stabilizing the ankle joint.

Step 5: Conclude that the correct answer is (d), as the fibula provides lateral stability to the ankle. Options (a), (b), and (c) are anatomically inaccurate, and option (e) is incorrect because neither (a) nor (b) are true.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Anatomy of the Fibula

The fibula is a long, thin bone located on the lateral side of the tibia in the lower leg. Unlike the tibia, it does not bear significant weight but serves primarily as a site for muscle attachment and provides stability to the ankle joint. Understanding its anatomical position and function is crucial for analyzing its role in the skeletal system.

Knee Joint Functionality

The knee joint is a complex hinge joint that primarily allows for flexion and extension of the leg. It is formed by the femur, tibia, and patella, with the fibula playing a minimal role in its articulation. Recognizing the components and mechanics of the knee joint is essential for understanding the fibula's limited involvement in this area.

Stability of the Ankle Joint

The ankle joint is stabilized by various ligaments and bones, including the fibula, which provides lateral support. This stability is crucial for maintaining balance and preventing injuries during movement. A clear grasp of how the fibula contributes to ankle stability helps clarify its functional importance in the lower extremity.

Multiple Choice

People who lift weights or participate in similar resistance exercise will typically have bones that are thicker and even restructured internally compared to people who do not lift weights. This increased thickness and restructuring results in stronger bones. As described here, is the difference between people who lift weights and those who don't a difference in anatomy or a difference in physiology?

Which describes an activity that would most likely be performed by someone that considers themselves a physiologist?
