Answer 14

synovial joints

Question 15

two parts of the synovial joint

Answer 15

articular capsule and articular cartilage

Question 16

part of synovial joint. hollow cylinder of dense irregular CT binding bones that contains synovial fluid

Answer 16

articular capsule

Question 17

part of synovial joint. pads of hyaline cartilage on the ends of bones.

Answer 17

articular cartilage

Question 18

ligaments with in or just outside the joint. they help increase joint stability.

Answer 18

reinforcing ligaments

Question 19

pads of fibrocartilage with in joint that mainly function to absorb shock

Answer 19

menisci

Question 20

independent synovial capsules filled with synovial fluid surrounding synovial JOINTS. they prevent friction.

Answer 20

bursae

Question 21

independent synovial capsules filled with synovial fluid wrapped around TENDONS.

Answer 21

tendon sheets

Question 22

inflammation of the bursae is called

Answer 22

bursitis

Question 23

inflammation of the tendon sheets is called

Answer 23

tendonitis

Question 24

4 factors influencing joint stability

Answer 24

end of bone shape, reinforcing ligaments, menisci, skeletal muscle crossings.

Question 25

types of synovial joints

Answer 25

ball + socket, hinge, condylar, pivot, and plane joints.

Question 26

type of synovial joint. allows greatest range of motion. (shoulder/hip)

Answer 26

ball + socket joints

Question 27

type of synovial joint. allows for swinging motion, flexion/extension. (finger/elbow/knee)

Answer 27

hinge joints

Question 28

type of synovial joint. a cross of ball+socket joint and hinge joints. (inbetween fingers and hands)

Answer 28

condylar joints

Question 29

type of synovial joint. allows pivoting and twisting. (b/w C1+ C2, b/w ulna + radius)

Answer 29

pivot joints

Question 30

type of synovial joint. allows rocking motion b/w bones (b/w carpals and b/w tarsals)

Answer 30

plane joints

Question 31

type of joint injury from overtwisting/hyperextending a joint.

Answer 31

sprain

Question 32

this is NOT a joint injury. its a muscle injury**

Answer 32

strain

Question 33

type of joint injury. bones of joint come out of alignment

Answer 33

dislocation

Question 34

type of joint injury from an increased compression within a joint. (AKA as torn meniscus)

Answer 34

cartilage tears

Question 35

Joint disease caused by chronic joint inflammation

Answer 35

Arthritis

Question 36

3 forms of arthritis

Answer 36

osteoarthritis, rheumatoid arthritis, gouty arthritis

Question 37

type of arthritis. (“wear + tear” arthritis) articular cartilage wears down leading to exposed bone tissue that remodels into bone spurs

Answer 37

osteoarthritis

Question 38

type of arthritis. (autoimmune disease) immune system attacks and destroys synovial joint tissue. scar tissue forms across joint causing the bones fuse together.

Answer 38

rheumatoid arthritis

Question 39

type of arthritis. (“gout”) crystals made of uric acid form within synovial joints. form in cool temp.

Answer 39

gouty arthritis
