A&p I Chapter 8 Joints

Front 1

articulation

Back 1

the sites where two or more bones meet

Front 2

amphiarthosis

Back 2

slightly moveable joints

Front 3

suture

Back 3

seams that occur only between the bones of the skull

Front 4

syntosis

Back 4

fibrous tissue that ossifies with age

Front 5

synchondrosis

Back 5

bar or plate of cartilage

Front 6

synovial joints

Back 6

joints where bones are seperated by a fluid filled joint cavity

Front 7

synarthroses

Back 7

immovable joints

Front 8

diarthroses

Back 8

freely movable joints

Front 9

syndesmoses

Back 9

bones are connected by a liament, a cord or a band of fibrous tissue

Front 10

gomphoses

Back 10

peg in socket fibrous joint. the only example is the articulation of a tooth with its socket

Front 11

symphysis

Back 11

articular surface of the bones are covered with articular (hyaline) cartilage

Front 12

bursa

Back 12

bags of lubrican that act to reduce friction between joint structures during joint activity

Front 13

insertion

Back 13

attached to movable bone

Front 14

origin

Back 14

attached to least movable bone

Front 15

extension

Back 15

reverse of flexion, increases the angle between the articulating bones.

Front 16

adduction

Back 16

"moving toward" opposite of abduction. Toward the midline
"digits toward hand or foot"

Front 17

flexion

Back 17

decreases the angle of the joint and brings the articulating bones closer together. "head down on chest"

Front 18

abduction

Back 18

"moving away" away from midline "raising the arm laterally"

Front 19

rotation

Back 19

turning of a bone one its long axis " common at the hip and shoulder joints"

Front 20

supination

Back 20

"turning backward" refer to the movement of the radius aroud the ulna "hand anterior or superior"

Front 21

pronation

Back 21

"turning forward" refer to the movement of the radius aroud the ulna "hand posterior or inferior"

Front 22

circumduction

Back 22

using flexion,extension, abduction and adduction in a wide arch.

Front 23

inversion

Back 23

sole of the foot turns medially

Front 24

eversion

Back 24

sole of the foot turns laterally

Front 25

protraction

Back 25

protracted when you stick out your jaw

Front 26

retraction

Back 26

when you move your jaw back to original position

Front 27

elevation

depression

Back 27

moving a body part superiorly

moving a body part inferiorly

Front 28

luxation

subluxation

Back 28

dislocation, toatally apart

loss of use of the joint

Front 29

opposition

Back 29

opposition of the thumb, makes the human hand a fine tool for manipulating objects

Front 30

tendon

Back 30

rope like tendon that anchors the muscle to the connective tissue

Front 31

aponeurosis

Back 31

sheet like tendon that anchors the muscle to the CT

Front 32

sarcolemma

Back 32

plasma membrane of the muscle cell

Front 33

sarcoplasm

Back 33

similar to the cytoplasm of other cells but contains an unusually large amount of glycosomes and myoglobin

Front 34

sarcoplasmic reticulum

Back 34

elaborate smooth endoplasmic reticulum

Front 35

myoglobin

Back 35

red pigment that stores O2 and is similar to hemoglobin

Front 36

neuromuscular junction

Back 36

each muscle fiber has only one neuromuscular junction

Front 37

synapse

Back 37

gap between the axon terminal and the muscle fiber
