Joints- Structure, function, and movement 2

Question 1

What is an Amphiarthrosis?

Answer 1

A joint that allows limited movement, providing a mix of stability and some motion.

Question 2

What is Articular Cartilage?

Answer 2

Another term for the hyaline cartilage that covers the articulating surfaces of bones within a synovial joint.

Question 3

Define Ball-and-socket joint.

Answer 3

A type of synovial joint capable of movement in any plane and circumduction.

Question 4

What is a Bursa?

Answer 4

A fluid-filled sac that acts as a cushion between bones and soft tissues or tendons to reduce friction and facilitate movement.

Question 5

What type of connective tissue protects bone from friction?

Answer 5

Cartilage.

Question 6

What are the two types of cartilage found in joints?

Answer 6

• Hyaline
• Fibrocartilage

Question 7

What is a Cartilaginous Joint?

Answer 7

A structural classification for joints that are partially moveable (amphiarthrosis) and have fibrocartilage pads between the ends of the bones.

Question 8

Define Diarthroses.

Answer 8

A functional classification for a joint that allows the most movement, permitting free motion in most directions.

Question 9

What is an Ellipsoid joint?

Answer 9

A type of synovial joint where an oval-shaped end of a bone articulates with an elliptical basin, permitting flexion, extension, abduction, and adduction.

Question 10

What characterizes a Fibrous Joint?

Answer 10

A structural classification for joints that are immovable (synarthrosis) and are joined by fibrous connective tissue.

Question 11

What is an example of a Fibrous Joint?

Answer 11

Sutures.

Question 12

What is a First-class lever?

Answer 12

A lever where the fulcrum is positioned between the force and the resistance.

Question 13

What serves as the fulcrum in the body?

Answer 13

Joints.

Question 14

Define Gliding joint.

Answer 14

A type of synovial joint found between two flat surfaces that allows at least one movement.

Question 15

What is a Gomphosis?

Answer 15

A type of fibrous joint that is an example of a synarthrosis (immovable).

Question 16

What is a Hinge Joint?

Answer 16

A type of synovial joint that allows flexion and extension.

Question 17

What type of cartilage makes up articular cartilage in joints?

Answer 17

Hyaline Cartilage.

Question 18

What is the definition of a Joint?

Answer 18

The point of contact between two bones.

Question 19

What are Ligaments?

Answer 19

Tough, elastic bands of connective tissue that connect bones together, stabilizing and strengthening joints.

Question 20

What are Menisci?

Answer 20

C-shaped pieces of cartilage in the knee that act as shock absorbers, transmit weight, and provide stability.

Question 21

What is a Pivot Joint?

Answer 21

A type of synovial joint that allows one bone to rotate around the surface of another bone.

Question 22

What is a Saddle joint?

Answer 22

A type of synovial joint with convex and concave articulating surfaces.

Question 23

What is a Second-class lever?

Answer 23

A lever where the resistance lies between the fulcrum and the point of force.

Question 24

What is the definition of Sutures?

Answer 24

A type of fibrous joint that is immovable (synarthrosis) and found only in the cranium.

Question 25

Define Symphysis.

Answer 25

A type of secondary cartilaginous joint connected by fibrocartilage that is slightly movable.

Question 26

What is the classification of Synarthroses?

Answer 26

A functional classification for a joint that does not move under normal conditions.

Question 27

What is Synchondrosis?

Answer 27

A primary cartilaginous joint connected by hyaline cartilage, which can be temporary or permanent.

Question 28

What is Syndesmosis?

Answer 28

A type of fibrous joint that is slightly movable (amphiarthrotic) and connects two bones with ligaments or a strong membrane.

Question 29

What is the Synovial Cavity?

Answer 29

The fluid-filled space within a synovial joint, surrounded by a fibrous capsule.

Question 30

What is Synovial Fluid?

Answer 30

A thick, viscous liquid found in synovial joints that lubricates and protects the ends of bones.

Question 31

What is a Synovial Joint?

Answer 31

The most common type of joint; a freely moveable (diarthrosis) joint responsible for movement between long bones.

Question 32

What does the Synovial Membrane do?

Answer 32

Produces the lubricating synovial fluid.

Question 33

What are Tendons?

Answer 33

Fibrous tissues that connect muscles to bones and act as a mechanical bridge to transmit muscle forces.

Question 34

What is a Third-class lever?

Answer 34

A lever where the force is applied between the fulcrum and the resistance.
