Question 1

Which structural classification of joints is characterized by bones joined by dense fibrous connective tissue, lacks a joint cavity, and is mostly immovable?

Accepted Answer

Fibrous joints

Question 2

A patient presents with a torn meniscus in the knee. Which of the following best describes the consequences of removing the entire meniscus?

Accepted Answer

The knee joint loses stability and is at increased risk for osteoarthritis.

Question 3

Which ligament in the knee prevents forward sliding of the tibia on the femur and checks hyperextension?

Accepted Answer

Anterior cruciate ligament

Question 4

Which movement is defined as moving a limb away from the midline or median plane?

Accepted Answer

Abduction

Question 5

A synovial joint is characterized by all of the following EXCEPT:

Accepted Answer

Bones joined by dense fibrous connective tissue without a cavity

Question 6

Which of the following best describes the function of synovial fluid during joint movement?

Accepted Answer

It lubricates and nourishes articular cartilage cells through weeping lubrication.

Question 7

Which structural category of synovial joint allows multiaxial movement, including flexion, extension, adduction, abduction, and rotation?

Accepted Answer

Ball-and-socket joint

Question 8

A patient is unable to perform dorsiflexion at the ankle. Which movement is impaired?

Accepted Answer

Lifting the foot so its superior surface approaches the shin

Question 9

Which of the following is TRUE regarding the hip joint?

Accepted Answer

The acetabular labrum is a fibrocartilage structure that deepens the socket.

Question 10

Which of the following best explains why muscle tone is the most important stabilizing factor for synovial joints?

Accepted Answer

Low-level muscle contraction creates tension in tendons crossing the joint, maintaining stability.

Question 11

Which joint movement occurs when the distal end of a limb moves in a circle while the point of the cone remains stationary?

Accepted Answer

Circumduction

Question 12

A patient presents with pain and swelling in the wrist after repetitive movements. Which joint disorder is most likely?

Accepted Answer

Tendonitis

Question 13

Which equation best represents the relationship between muscle contraction and joint movement, where $$F is $$force, $$d is $$distance, and $$W is $$work?

Accepted Answer

$$W = F 	imes d$$

Question 14

Which of the following is a peg-in-socket joint, and what is its functional classification?

Accepted Answer

Gomphosis; synarthroses

Question 15

A patient with rheumatoid arthritis is experiencing chronic inflammation of the synovial membrane. Which of the following best describes the underlying mechanism?

Accepted Answer

Autoimmune attack leads to inflammation and scar tissue formation in the synovial membrane.

Question 16

Which of the following movements is possible at the temporomandibular joint?

Accepted Answer

Depression, elevation, and gliding

Question 17

Which of the following best describes the function of articular discs (menisci) in synovial joints?

Accepted Answer

They minimize wear and tear, improve bone fit, and provide stability.

Question 18

Which of the following is TRUE regarding bursae and tendon sheaths?

Accepted Answer

They are bags of lubricant that reduce friction between adjacent structures during joint activity.

Question 19

A patient with gouty arthritis should avoid which of the following foods to reduce uric acid accumulation?
