Questions from this subtopic

Each one with the model answer underneath.

1. 1

   What type of joint is the hip, and which bones form it?

   Model answer

   The hip is a ball and socket joint. The head of the femur sits in the acetabulum of the pelvis.

2. 2

   Which muscle is the agonist for hip flexion?

   Model answer

   The iliopsoas is the agonist for hip flexion, as when a sprinter drives the knee forward. The gluteus maximus is its antagonist.

3. 3

   Which muscle extends the hip as a sprinter drives out of the blocks?

   Model answer

   The gluteus maximus is the agonist for hip extension. The iliopsoas is the antagonist.

4. 4

   Which muscles abduct the hip?

   Model answer

   The gluteus medius and gluteus minimus abduct the hip. The adductor muscles are the antagonists.

5. 5

   Name the three adductor muscles of the hip and the movement they produce.

   Model answer

   The three adductors are adductor longus, adductor brevis and adductor magnus. The adductors pull the leg towards the midline in hip adduction.

6. 6

   Which muscles produce medial and lateral rotation at the hip?

   Model answer

   The gluteus medius and gluteus minimus produce medial rotation of the hip. The gluteus maximus produces lateral rotation.
