Flashcards in Lab 19- Joint structure and movements (test 2) Deck (27):
1

fibrous joints

suture- dense fibrous connective tissue (synarthrosis)
gomphosis- periodontal ligament (synarthrosis): tooth sockets
Syndesmosis- dense fibrous connective tissue (amphiarthrosis): tibiofibular joint

2

cartilaginous joints

synchondrosis- hyaline cartilage (synarthrosis): epiphyseal plates
symphysis- fibrocartilage (amphiarthrosis): pubic symphysis, intervertebral discs

3

synovial joints

all have articular cartilage, a synovial membrane and a cavity filled with synovial fluid and are diarthrosic
Ball-and-socket: all planes of movement (hip and shoulder)
Hinge: flexion and extension (elbow, knee, intephalangeal)
Condylar (ellipsoid): flexion, extension, abduction, adduction (radiocarpal, metacarpophalangeal)
Pivot: rotation (radioulnar at elbow, dens at atlas)
Saddle: mainly two planes (base of thumb with trapezium)
Plane (gliding): sliding or twisting (intercarpal, intertarsal)

4

flexion

decrease of angle (usually in the sagittal plane)

5

lateral flexion

bending of the trunk (vertebral column) to the side

6

extension

increase of an angle (usually in the sagittal plane)

7

hyperextension

extension beyond anatomical position

8

abduction

movement away from the midline (frontal plane)

9

adduction

movement toward the midline (usually in the frontal plane)

10

circumduction

circular movement
-combines abduction, adduction, flexion, and extension)

11

rotation

movement of a part around its long axis

12

medial rotation

internal rotation

13

lateral rotation

external rotation

14

gliding

back and forth and side to side sliding movements of plane joints

15

supination

movement of PALM of hand anteriorly or upward

16

pronation

movement of PALM of hand posteriorly or downward

17

elevation

movement of body part upward

18

depression

movement of body part downward

19

dorsiflexion

movement of the ANKLE joint in the direction of the shin

20

plantar flexion

movement of the ANKLE joint as to stand on the toes

21

inversion

medial movement of the SOLE OF THE FOOT at the ankle

22

eversion

lateral movement of the SOLE OF THE FOOT at the ankle

23

protraction

anterior movement in the transverse plane

24

retraction

posterior movement in the transverse plane

25

excursion

special movement to the MANDIBLE when grinding food
*lateral-movement of the mandible laterally
*medial-movement of the mandible medially

26

opposition

movement of the THUMB to touch another finger of the same hand

27

reposition

return of THUMB to anatomical position
