movement

Question 1

pivot

Answer 1

allows rotation as well as twisting movements back and forth (where the humerus meets the radius and ulna at the elbow)

Question 2

ball and socket

Answer 2

lots of maneuverability; allows rotational movements, abduction/adduction, flexion/extension (shoulder and hip joint)

Question 3

hinge

Answer 3

only moves in one direction (like a door hinge) (elbow and interphalangeal joints)

Question 4

condylar

Answer 4

like a pedestal with a joint on top; allows movements like flexion/extension, as well as abduction/adduction (wrist)

Question 5

saddle

Answer 5

allows opposition movements as well as flexion/extension, abduction/adduction (thumb joint)

Question 6

gliding

Answer 6

when one flat bone surface glides or slips over another (back and forth or side to side) (intercarpal joints in wrist and ankle)

Question 7

pronation

Answer 7

turn/twist backward

Question 8

circumduction

Answer 8

moving limb in a circle (making circles with arms)

Question 9

elevation and depression

Answer 9

lifting (then lowering) a body part superiorly (shrugging your shoulders, jaw-dropping)

Question 10

abduction

Answer 10

moving away; moving a limb away from the median plane, along the frontal plane

Question 11

supination

Answer 11

turn/twist forward

Question 12

adduction

Answer 12

moving toward; opposite of abduction

Question 13

ligaments

Answer 13

attaches bone to bone

Question 14

tendons

Answer 14

attaches muscle to bone

Question 15

contract

Answer 15

either to shorten or undergo an increase in tension

Question 16

isotonic

Answer 16

causes a change in the length of muscles

Question 17

synarthroses

Answer 17

non moving joints (skull)

Question 18

diathroses

Answer 18

freely moving joints (knee)

Question 19

amphiarthrosis

Answer 19

slightly moving joints (pubic bone)

Question 20

fibrous joint

Answer 20

connect bones with the collagen fibers of dense connective tissue (mostly immovable)

Question 21

cartilaginous joint

Answer 21

connect bones with cartilage (can be rigid but also slightly movable)

Question 21

synovial joint

Answer 21

connect bone with dense connective tissues and a fluid-filled joint cavity (allows them to be freely movable) (all are diarthroses)

Question 22

flexion

Answer 22

bending in a way that decreases the angle of the joint so the articulating bones get closer

Question 23

extension

Answer 23

reverse of flexion

Question 24

bones in the arm

Answer 24

humerus, radius, ulna, carpals, metacarpals, phalanges

Question 25

isometric

Answer 25

no change in length
