Question 1

Which of the following best explains why the shoulder joint is more prone to dislocation compared to the sutures of the skull?

Accepted Answer

The shoulder joint has a greater range of motion, which decreases its stability.

Question 2

A patient presents with pain and swelling in a joint that is classified as a diarthrosis. Which of the following best describes the functional characteristics of this joint?

Accepted Answer

It is freely movable and allows for a wide range of motion.

Question 3

Which of the following is a correct pairing of structural and functional joint classifications?

Accepted Answer

Suture – Fibrous joint – Synarthrosis

Question 4

Which of the following statements about syndesmoses is FALSE?

Accepted Answer

Syndesmoses are composed of loose connective tissue to allow for free movement.

Question 5

A child’s epiphyseal plate is an example of which type of joint, and what is its primary function?

Accepted Answer

Synchondrosis; allows for bone growth during development

Question 6

Which of the following best describes the process of weeping lubrication in synovial joints?

Accepted Answer

Synovial fluid is squeezed out of articular cartilage during compression and reabsorbed during decompression.

Question 7

Which of the following is NOT a unique characteristic of synovial joints?

Accepted Answer

Presence of ligaments

Question 8

A patient with rheumatoid arthritis experiences pain in joints that are classified as diarthroses. Which of the following best explains why?

Accepted Answer

Diarthroses allow for a wide range of motion, increasing wear and tear.

Question 9

Which of the following structures is responsible for anchoring teeth to their sockets in the jaw?

Accepted Answer

Periodontal ligament

Question 10

Which of the following joint types is best suited to withstand compressive forces and absorb shock in the midline of the body?

Accepted Answer

Symphysis

Question 11

If the ligaments connecting the tibia and fibula were to lengthen, what would be the expected effect on the movement at the syndesmosis joint?

Accepted Answer

The joint would become more movable.

Question 12

Which of the following is a FALSE statement regarding the classification of joints?

Accepted Answer

All amphiarthroses are in the axial skeleton.

Question 13

Which of the following best describes the role of articular cartilage in synovial joints?

Accepted Answer

All three answers above are correct.

Question 14

A patient presents with pain in the knee joint due to insufficient synovial fluid. Which structure is most likely malfunctioning?

Accepted Answer

Synovial membrane

Question 15

Which of the following joint types is primarily responsible for allowing rotation of the forearm?

Accepted Answer

Syndesmosis between radius and ulna

Question 16

Which of the following is NOT a structural classification of joints?

Accepted Answer

Diarthroses

Question 17

Which of the following best describes the relationship between joint mobility and stability?

Accepted Answer

The greater the range of motion, the less stable the joint.

Question 18

Which of the following is a unique feature of synovial joints?

Accepted Answer

Presence of a joint cavity

Question 19

Which of the following statements about the development of sutures and gomphoses is TRUE?

Accepted Answer

They both start off less developed at birth and continuously become more rigid throughout life.
