articulations quiz

Question 1

synarthrosis

Answer 1

joint allows no motion between bones

Answer 5

skull

Question 6

gomphosis example

Answer 6

tooth, mandible/maxilla

Question 7

syndesmosis example

Answer 7

radius/ulna, fibula/tibia

Question 8

cartilaginous joint

Answer 8

joints held together by cartilage, neither synovial cavity nor articular capsule

Question 9

synchondrosis example

Answer 9

epiphyseal plate

Question 10

symphisis examples

Answer 10

intervertebral joint, pubic symphsis

Question 11

synovial joint

Answer 11

joints have fluid filled synovial cavity between bones that are enclosed within and articular capsule

Question 12

gliding(plane)

Answer 12

simplest, least mobile, 2 bone surfaces who sit together, nonaxial
example: intercarpals of wrist, intertarsals of ankle

Question 13

hinge

Answer 13

convex surface of one bone fits into a concave depression of another
example: elbow, knee, interphalangeal of toes and fingers

Question 14

ellipsoid (condyloid)

Answer 14

biaxial joint in which oval convex surface of one bone fits into shallow concave of another
example: knuckles

Question 15

pivot

Answer 15

unaxial joint where rounded surface of one bone fits into a groove on the surface of another
example: atlantoaxial joint between 1st and 2nd cervical vertebrae

Question 16

saddle

Answer 16

complimentary fit
example: carpometacarpal between thumb and trapezium

Question 17

ball and socket

Answer 17

multiaxial, ball shaped, fits into cup
example: shoulder and hip

Question 18

abduction

Answer 18

moving away from body, subtracting

Question 19

adduction

Answer 19

moving towards the body, adding

Question 20

circumduction

Answer 20

a freely moveable distal bone moves around a stationary proximal bone in a cone-shaped motion.

Question 21

depression

Answer 21

movement of a body part in an inferior direction

Question 22

dorsiflexion

Answer 22

the angle between the foot and the tibia decreases

Question 23

elevation

Answer 23

the mandible is pulled up toward the maxilla in a superior direction

Question 24

eversion

Answer 24

which the plantar surface of the foot rotates laterally away from the midline of the body

Question 25

extension

Answer 25

increases the angle between articulating bones.

Question 26

flexion

Answer 26

decreases the angle between articulating bones by bringing the two bones closer together

Question 27

inversion

Answer 27

otational motion of the foot in which the plantar surface (the sole of the foot) rotates medially toward the midline of the body (

Question 28

lateral flexion

Answer 28

sideways movement, such as when you tilt your head to one side or the other toward the shoulder

Question 29

opposition

Answer 29

involves movement of the thumb across the palmar surface of the hand

Question 30

plantar flexion

Answer 30

the angle between the foot and the tibia increases—the toes point toward the ground

Question 31

pronation

Answer 31

rotation of the hand and forearm so that the palm faces backwards or downwards.

Question 32

rotation

Answer 32

nonangular, pivoting motion, in which one bone rotates or twists on an imaginary line running down its middle, known as its longitudinal axis.

Question 33

internal rotation

Answer 33

point towards body midline

Question 34

external rotation

Answer 34

point towards away midline

Question 35

supination

Answer 35

rotation of the forearm and hand so that the palm faces forward or upward

Question 36

hyperextension

Answer 36

extension beyond the anatomical position of the joint

Question 37

reposition

Answer 37

return of the thumb to its anatomical position

Question 38

protraction

Answer 38

moves a body part in the anterior direction.

Question 39

retraction

Answer 39

the body part moves posteriorly
