Module 29 - Joints: Movement

Question 1

give the four types of movement in synovial joints

Answer 1

gliding, angular, circular, special movements

Question 2

what are gliding movements

Answer 2

vertebrae, carpals
gliding between carpals
happens at plane joints

Question 3

what is an angular movement

Answer 3

when one part of linear structure is bent relative to another part of the structure creating an angle

Question 4

give the 2 ways to describe flexion and extension

Answer 4

flexion
- to bend or decrease the angle
- movement in the anterior direction

extension
- to straighten or increase the angle
- movement in the posterior direction

Question 5

what is hypertension

Answer 5

extension beyond anatomical position

Question 6

what are the exceptions to the anterior/posterior definition of extension and flexion?

Answer 6

knee and lateral flexion
knee bent = flexion, standing = extension.
ear towards hip laterally = lateral flexion

Question 7

give the 2 angular movements that have to do with feet

Answer 7

plantar flexion - movement toward the plantar surface of the foot
Dorsiflexion - movement away from the plantar surface of the foot.

btw plantar = bottom of foot.

Question 8

Name the 2 movements that are relative to the midline of the body or body part

Answer 8

abduction and adduction
abduction - movement away from the midline
adduction - movement towards midline

Question 9

what is radial deviation/ulnar deviation

Answer 9

radial deviation - hand movement towards thumb
ulnar deviation - hand movement towards pinky

Question 10

what is medial and lateral rotation

Answer 10

medial = rotation of hand and arm going inwards
lateral = rotation of hand and arm going outwards

Question 11

differentiate supination and pronation

Answer 11

supination - hand upwards like when u hold a soup
pronation - hand facing downwards cant hold soup

Question 12

which has uncrossed bones: supination or pronation

Answer 12

supination

Question 13

which joints can have circumduction?

Answer 13

shoulder, hip and wrist

Question 14

Answer 14

Question 15

Answer 15

Question 16

what is elevation and depression and where can it happen

Answer 16

elevation - moves structure superiorly
depression - moves it inferiorly

happens at scapula and mandible
depression of mandible = opening of mouth

Question 17

what is protraction and retraction and where can it happen

Answer 17

protraction - anterior movement in transverse plane
retraction - posterior movement in transverse plane.

protraction of scapula is like putting yourself into a ball for sleep.

happens in mandible, clavical and scapula

Question 18

what is opposition and reposition and where can it happen

Answer 18

opposition - when the thumb and little finger are brought together
reposition - when they return to neutral

happens in fingers only

Question 19

what is inversion and eversion and where can it happen

Answer 19

inversion - turning the ankle - plantar surface faces medially
eversion - turning the ankle - plantar surface faces laterally
happens in intertarsal joints of foot and not the ankle since its a hinge joint.
