Q: Which equation best describes the relationship between joint stability and the number of reinforcing ligaments?

$$\text{Stability} = \text{Number of ligaments} + \text{Muscle tone}$$

Q: Which equation best represents the relationship between joint movement and fiber length in syndesmoses?

$$\text{Movement} \propto \text{Fiber length}$$

Question 11

A patient with gouty arthritis is advised to avoid foods high in purines. Which of the following is a likely reason for this recommendation?

Accepted Answer

Purines increase uric acid production, leading to crystal deposition in joints

Question 13

Which of the following is NOT a feature of synovial joints?

Accepted Answer

Fibrous connective tissue joining bones

Question 14

Which ligament is slack during most hip movements and contains an artery that supplies the head of the femur?

Accepted Answer

Ligamentum teres

Question 15

Which movement describes turning a bone around its own long axis, such as the rotation of the humerus or femur?

Accepted Answer

Rotation

Question 16

A patient presents with inflammation of a bursa after repetitive friction at the shoulder. What is the most likely diagnosis?

Accepted Answer

Bursitis

Question 17

Accepted Answer

Symphysis

Question 18

Which equation best represents the relationship between joint movement and fiber length in syndesmoses?

Accepted Answer

$$	ext{Movement} \propto 	ext{Fiber length}$$

Question 19

Which synovial joint type is formed by the trochlear notch of the ulna articulating with the trochlea of the humerus, allowing only flexion and extension?

Accepted Answer

Hinge joint
