Flashcards in Chapter 8 Deck (32):
1

joint classification that does not allow any movement between articulating bones

synarthrosis

2

joint that allows only a small amount of movement between articulating bones

Amphiarthrosis

3

joint that allows freely moveable, allowing a wide variety of specific movements

Diarthrosis

4

joint classification; joints that are fastened together by dense regular collagenous connective tissue without a joint space between articulating bones

fibrous joint

5

joint classification; joints that are fastened together with cartilage without a joint space

cartilagenous joints

6

joint classification; diarthrosis joints have a layer of hyaline cartilage on articulating surface of each bone; joint space is a fluid-filled cavity found between articulating bones

synnovial joints

7

what're 3 types of fibrous joints

suture, gomphoses, syndesmoses

8

immoveable joint between edges of bones that make up cranium; fully fused sutures are very stable, well suited for protecting brain

suture

9

immoveable joint between each tooth and its bony socket in jaw; periodontal ligament is a strong fibrous membrane that links tooth firmly to jaw bone

gomphosis

10

joint between tibia, fibula, ulna, and radius; bones are joined by an interosseous membrane or ligament composed of dense regular collagenous connective tissue, which allows for small amount of movement

syndemosis

11

joint where bones are united by a fibrocartilaginous pad or plug

symphysis

12

space found between articulating bones

joint cavity

13

double-layered structure (fibrous outer layer and a inner layer- synovial membrane)

articular cavity

14

what are the 3 functions of synovial fluid

1. lubricates joints when they're articulating
2. Serves a metabolic function (acts as a medium that oxygen and other nutrients can move through)
3. Provides for shock absorption

15

Provides a smooth surface for articulating bones to interact; reduces wear and tear created by friction; covers all exposed articulating bones within a joint; avascular

articular cartiledge

16

decreases angle between articulating bones by bringing bones closer to one another

flexion

17

increases angle between articulating bones, is opposite of flexion; articulating bones move away from one another

extension

18

extension beyond anatomical position of joint

hyperextension

19

motion of a body part away from midline of body or another reference point

abduction

20

motion of a body part towards midline of body or another reference point; opposite of abduction

adduction

21

only unpaired angular movement where a freely moveable distal bone moves on a fixed proximal bone in a cone-shaped motion; movement in a circle

circumduction

22

movement around a central axis

rotation

23

moves a body part in a inferior direction

depression

24

moves a body part in a superior direction

elevation

25

first carpometacarpal joint allows thumb to move across palmar surface of hand

opposition of thumb

26

is opposite movement that returns thumb to its anatomical position

reposition of thumb

27

moves a body part in an anterior direction

protraction

28

moves a body part in a posterior direction

retraction

29

is a rotational motion in which plantar surface of foot rotates medially toward midline of body

inversion

30

rotates foot laterally away from midline

eversion

31

is a movement where angle between foot and leg decreases

dorsiflexion

32

angle between foot and leg increases during ______

plantarflexion
