Gomphosis

Question 3

A patient presents with limited movement in the distal tibiofibular joint. Which type of joint is this, and what tissue primarily holds it together?

Accepted Answer

Fibrous joint (syndesmosis); dense fibrous connective tissue

Question 4

Which of the following movements at synovial joints involves a decrease in the angle between articulating bones?

Accepted Answer

Flexion

Question 5

The menisci of the knee joint serve which primary function?

Accepted Answer

Spread synovial fluid within the joint and improve fit between bones

Question 6

Which equation best represents the relationship between joint stability ($$S$$), depth of the socket ($$d$$), and ligament strength ($$L) in a $$ball-and-socket joint?

Accepted Answer

$$S = d 	imes L$$

Question 7

A football player suffers a tear in the anterior cruciate ligament (ACL) of the knee. Which of the following best describes the consequence?

Accepted Answer

Decreased stability of the knee joint, especially during rotation and extension

Question 8

Which of the following is TRUE regarding the shoulder (glenohumeral) joint?

Accepted Answer

It allows a wide range of motion at the expense of stability.

Question 9

Which movement describes turning the sole of the foot medially?

Accepted Answer

Inversion

Question 10

A patient is unable to perform abduction at the hip joint. Which muscle group is most likely affected?

Accepted Answer

Gluteal muscles

Question 11

Which of the following best explains why the hip joint is less mobile but more stable than the shoulder joint?

Accepted Answer

The hip joint has a deeper socket (acetabulum) and stronger ligaments.

Question 12

Accepted Answer

Synovial membrane

Question 13

Which of the following is a cartilaginous joint that allows slight movement and is found at the midline of the body?

Accepted Answer

Symphysis

Question 14

Which of the following is a function of synovial fluid?

Accepted Answer

Provides oxygen and nutrients to avascular articular cartilage

Question 15

A patient with osteoarthritis is most likely experiencing which pathological change?

Accepted Answer

Gradual loss of joint cartilage due to wear and abrasion

Question 16

Which movement at the temporomandibular joint allows the jaw to move forward?

Accepted Answer

Protraction

During a squat, which movement occurs at the knee joint as you lower your body?

Accepted Answer

Flexion

Question 18

Which of the following best describes circumduction at a synovial joint?

Accepted Answer

A combination of flexion, extension, abduction, and adduction resulting in a circular motion

Question 19

Which equation best represents the total range of motion ($$R) at a $$synovial joint as a function of joint type ($$J$$), ligament flexibility ($$F$$), and muscle strength ($$M$$)?

Accepted Answer

$$R = J 	imes F 	imes M$$

Question 20

Which of the following is TRUE regarding joint replacement surgery?

Accepted Answer

It is performed to replace joints damaged by disease or injury with artificial joints made of metal, ceramic, or plastic.
