Accepted Answer

A fibrous, synarthrotic joint

Question 3

Which type of joint is represented by the epiphyseal plate in the long bone image, and what is its main characteristic?

Accepted Answer

Synchondrosis; united by hyaline cartilage and is synarthrotic

Question 4

The intervertebral disc shown in the image is an example of which type of joint, and what is its main function?

Accepted Answer

Symphysis; allows limited movement and absorbs shock

Question 5

Which structure in a synovial joint is responsible for secreting synovial fluid and providing nourishment to articular cartilage?

Accepted Answer

Synovial membrane

Question 6

A meniscus, as seen in the knee joint image, serves which of the following functions?

Accepted Answer

Improves the fit between articulating bone surfaces and increases joint stability

Question 7

Which of the following best describes the role of bursae and tendon sheaths in synovial joints, as shown in the shoulder joint image?

Accepted Answer

They reduce friction between moving structures such as tendons and bones

Question 8

Which type of synovial joint is depicted in the image showing planar movement between carpal bones, and what is its main characteristic?

Accepted Answer

Nonaxial (plane/gliding) joint; allows sliding movements in multiple directions

Question 9

The elbow joint, as shown in the image, is an example of which type of synovial joint, and what movement does it allow?

Accepted Answer

Hinge joint; allows flexion and extension in one plane

Question 10

Which movement is demonstrated by the person moving their arm away from the midline in the labeled image?

Accepted Answer

Abduction

Question 11

A patient presents with pain, swelling, and bruising after twisting their ankle. The injury is diagnosed as a sprain. Which structure is most likely damaged?

Accepted Answer

Ligaments

Question 12

Which of the following is a distinguishing feature of rheumatoid arthritis compared to osteoarthritis?

Accepted Answer

It is an autoimmune disease that affects joints symmetrically and can cause systemic symptoms

Question 13

Which of the following best explains why the shoulder joint is more prone to dislocation than the hip joint?

Accepted Answer

The shoulder joint has a shallower socket and relies more on muscle tone for stability

Question 14

Which movement is shown when a person rotates their head to look over their shoulder, as labeled in the image?

Accepted Answer

Rotation

Question 15

A herniated disc involves the extrusion of which structure through the annulus fibrosus, and what is a common consequence?

Accepted Answer

Nucleus pulposus; impingement of nearby neural structures

Question 16

Which of the following best describes the movement called circumduction, as shown in the labeled image?

Accepted Answer

Movement of a limb in a circle, combining flexion, extension, abduction, and adduction

Question 17

Which of the following is true regarding the stability of synovial joints?

Accepted Answer

Muscle tone is the major stabilizing factor, especially in joints like the shoulder

Question 18

Which type of arthritis is associated with the deposition of uric acid crystals in joints, often affecting the big toe?

Accepted Answer

Gouty arthritis

Question 19

Which of the following best describes a pivot joint, as shown in the image of the proximal radioulnar joint?

Accepted Answer

Allows rotation around a single axis
