Which type of synovial joint allows for the greatest range of motion?

Answer 4

Ball-and-socket joints.

Question 5

What are the main components of a synovial joint?

Answer 5

Articular cartilage, synovial membrane, joint capsule, synovial fluid, ligaments, and sometimes menisci.

Question 6

Multiple Choice: Which of the following is NOT a type of synovial joint? A) Hinge B) Pivot C) Suture D) Ball-and-socket

Answer 6

C) Suture

Question 7

What role do ligaments play in synovial joints?

Answer 7

Ligaments connect bones to other bones and provide stability to the joint.

Question 8

True or False: The synovial membrane produces synovial fluid.

Answer 8

True

Question 9

Short Answer: Name one function of articular cartilage.

Answer 9

To reduce friction and absorb shock between articulating bones.

Question 10

What is the purpose of the joint capsule in synovial joints?

Answer 10

To enclose the joint and provide stability while allowing movement.

Question 11

Fill in the blank: Synovial joints are classified based on their __________.

Answer 11

shape and movement capabilities.

Question 12

Multiple Choice: Which type of synovial joint allows for rotation around a single axis? A) Hinge B) Pivot C) Saddle D) Plane

Answer 12

B) Pivot

Question 13

What is a meniscus in the context of synovial joints?

Answer 13

A crescent-shaped cartilage that provides cushioning and stability in some joints.

Question 14

True or False: Synovial joints can only move in one direction.

Answer 14

False

Question 15

Short Answer: Describe one way that synovial fluid contributes to joint health.

Answer 15

It nourishes the cartilage and helps to maintain joint lubrication.

Question 16

What is the significance of the articular cartilage’s smooth surface?

Answer 16

It minimizes friction during joint movement.

Question 17

Fill in the blank: The __________ is the outer layer of the joint capsule.

Answer 17

fibrous capsule.

Question 18

Multiple Choice: Which of the following joints is an example of a hinge joint? A) Knee B) Shoulder C) Wrist D) Ankle

Answer 18

A) Knee

Question 19

What type of movement does a saddle joint allow?

Answer 19

Biaxial movement, allowing flexion, extension, abduction, and adduction.

Question 20

True or False: The range of motion of synovial joints is limited by the surrounding muscles and ligaments.

Answer 20

True

Question 21

Short Answer: What type of synovial joint is found in the shoulder?

Answer 21

Ball-and-socket joint.

Question 22

What is the function of bursae in synovial joints?

Answer 22

To reduce friction between moving structures in the joint.

Question 23

Fill in the blank: The __________ joint is an example of a plane joint.

Answer 23

carpometacarpal joint of the thumb.

Question 24

Multiple Choice: Which synovial joint type is primarily involved in flexion and extension? A) Ball-and-socket B) Hinge C) Pivot D) Saddle

Answer 24

B) Hinge

Question 25

Short Answer: Name one common injury associated with synovial joints.

Answer 25

Sprains or dislocations.
