Textbook Question

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

a. The obturator foramen articulates with the head of the femur at the hip joint.

Verified step by step guidance

Step 1: Understand the anatomy of the obturator foramen. The obturator foramen is a large opening in the pelvis formed by the ischium and pubis bones. It primarily serves as a passageway for nerves and blood vessels, not as an articulation site.

Step 2: Review the anatomy of the hip joint. The hip joint is a ball-and-socket joint where the head of the femur articulates with the acetabulum of the pelvis, not the obturator foramen.

Step 3: Analyze the statement provided. The statement claims that the obturator foramen articulates with the head of the femur at the hip joint. Based on the anatomical facts, this is incorrect.

Step 4: Correct the false statement. The corrected statement should be: 'The acetabulum articulates with the head of the femur at the hip joint.'

Step 5: Verify your understanding by visualizing or referencing a diagram of the pelvis and femur to confirm the correct anatomical relationships.

Key Concepts

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

Obturator Foramen

The obturator foramen is a large opening in the pelvic bone formed by the ischium and pubis. It does not articulate with any bone but serves as a passage for nerves and blood vessels, specifically the obturator nerve and vessels. Understanding its anatomy is crucial for comprehending pelvic structure and function.

Hip Joint Anatomy

The hip joint is a ball-and-socket joint formed by the head of the femur and the acetabulum of the pelvis. This joint allows for a wide range of motion in the lower limb. Recognizing the components of the hip joint is essential for understanding its biomechanics and the implications of injuries or conditions affecting it.

Articulation

Articulation refers to the connection between two bones at a joint, allowing for movement and stability. In the context of the hip joint, the head of the femur articulates with the acetabulum, not the obturator foramen. Understanding articulation is vital for analyzing joint function and diagnosing joint-related issues.
