Exam 2 part 3

Question 1

arthon

Answer 1

joint

Question 2

joint

Answer 2

bt bones, bones and cartilage or bones and teeth
hold bones together
allow for growth
can loosen (hormones/childbirth)
pivot point for movement
range of motion: freely moveable to immovable
articular cartiagle -resembles hyaline cartialge but lacks perichondrium, matrix holds fluid, absorbs sock

Question 3

function classification

Answer 3

synarthrosis
amphiarthrosis
diarthrosis

Question 4

synarthrosis

Answer 4

immovable; bones very close together -may interlock

ex. tooth in alverolar process, suture

Question 5

amphiarthrosis

Answer 5

slightly movable; bones aprt
ma have cartilage bt bone
bt adjacent vertebrae, pubic symphysis
bones may be held by ligaments 
ex. bt tiba and fibula, bt ulna and radius

Question 6

diarthrosis

Answer 6

freely movable; bones often covered by articular cartilage

all have joint capsule

Question 7

structure classification

Answer 7

fibrous
cartilagenous
synovial joints

Question 8

fibrous

Answer 8

bones close together, immovable to slightly movable, fibrous (dense regular CT)

Question 9

fibrous joint types

Answer 9

suture
syndesomosis
gomphosis

Question 10

suture

Answer 10

fibrous joints no movement, thin layer of fibrous CT bonds bones together, interlock
synarthrosis

Question 11

syndesmosis

Answer 11

fibrous joint.
bones bound together by interosseous ligaments; some flexibility
amphiarthrosis

Question 12

gomphosis

Answer 12

fibrous joint.
process in bony socket
synarthrosis

Question 13

cartilagenous joint types

Answer 13

symphysis

synchondrosis

Question 14

symphysis

Answer 14

cartilagenous joint.
bone end is covered by articualr cartilage and fibrocartilage pad bt bones, cushions, small movement
amphiarthrosis

Question 15

synchondrosis

Answer 15

cartilagenous joints.
binding of bones by (hyaline) cartilage
synarthrosis
epiphyseal plate

Question 16

synovial joints

Answer 16

complex; allows for wide movement; strong; many types
all diarthrosis
bones separated by space 
articular cartilage covers bone
articular capsule
synovial membrane

Question 17

articular capsule

Answer 17

CT, surrounds bone ends

Question 18

synovial membrane

Answer 18

line joint capsule and secretes synovial fluid

lubricates, cushions, and nourishes

Question 19

menisci

Answer 19

fibrocartilage pads (2 per knee)

Question 20

tendons

Answer 20

connect muscle to bones
stablize joints
ex. rotator cuff-in shoulder

Question 21

bursae

Answer 21

fluid filled bags; cushion
inflammation -bursities
tendon sheath

Question 22

tendon sheath

Answer 22

modified bursa, covers tendon

Question 23

fat pads

Answer 23

associated with synovial membranes,

squishy -fills spaces as joint moves
