Accepted Answer

Fibrous joints

Question 3

Which of the following is an example of a syndesmosis, a type of fibrous joint?

Accepted Answer

The interosseous membrane between the radius and ulna

Question 4

Cartilaginous joints are classified into synchondroses and symphyses. Which of the following best describes a synchondrosis?

Accepted Answer

A joint where bones are united by hyaline cartilage, such as the epiphyseal plate.

Question 5

Which structural feature is unique to synovial joints and is essential for their function?

Accepted Answer

Presence of a joint cavity filled with synovial fluid

Question 6

Which of the following is considered the most important natural factor stabilizing synovial joints?

Accepted Answer

The tone of the surrounding muscles

Question 7

A patient presents with a torn anterior cruciate ligament (ACL) in the knee. Which type of joint injury does this represent, and what is a common symptom?

Accepted Answer

Sprain; inability to move the joint and swelling

Question 8

Which movement occurs when you decrease the angle between two bones, such as bending the elbow?

Accepted Answer

Flexion

Question 9

Which synovial joint type allows movement in multiple axes and is exemplified by the shoulder joint?

Accepted Answer

Ball-and-socket joint

Question 10

A patient with rheumatoid arthritis is most likely to experience which of the following symptoms?

Accepted Answer

Joint pain and swelling due to autoimmune inflammation

Question 11

Which of the following equations best represents the relationship between force ($$F$$), lever arm ($$r$$), and torque ($$	au) in a $$synovial joint?

Accepted Answer

$$	au = F 	imes r$$

Question 12

Which movement is described by moving a limb away from the midline of the body?

Accepted Answer

Abduction

Question 13

The temporomandibular joint (TMJ) is unique among synovial joints because it allows which combination of movements?

Accepted Answer

Gliding and hinge movements

Question 14

Which of the following best describes the anatomical characteristics of the hip joint?

Accepted Answer

A ball-and-socket joint with a deep socket and strong ligaments, allowing stability and wide range of motion

Question 15

Which of the following is a real-life example of a pivot joint?

Accepted Answer

The atlantoaxial joint between the first and second cervical vertebrae

Question 16

Which equation would you use to calculate the range of motion ($$ROM) in $$degrees for a synovial joint, given the initial angle ($$\$$theta_1$$) and final angle ($$\$$theta_2$$)?

Accepted Answer

$$ROM = \$$theta_2$$ - \$$theta_1$$

Question 17

Which of the following best describes the movement allowed by a hinge joint?

Accepted Answer

Movement in one plane: flexion and extension

Question 18

A patient with gouty arthritis is most likely to have which underlying cause?

Accepted Answer

Deposition of uric acid crystals in the joint

Question 19

Which of the following is a multi-step scenario: A football player lands awkwardly and experiences a dislocation of the shoulder joint. Which synovial joint type is involved, and what is the primary factor contributing to the instability?

Accepted Answer
