Anatomy Bones And Muslces

Front 1

3 functional classes of joint

Back 1

based on amountof movement
synarthrodial-immovable(skull
amphirthrodial-slighty movable
diathrodia--freely movable

Front 2

3 stuctural classes
functional classification

Back 2

fibrous joints
cartilginous joints
synovial joint

Front 3

fibrous joints

Back 3

bones in close contact
fastened tigtly by thin layer of fibrous ct
no motion or very slight
3 typesof fibrous joints

Front 4

3 fibrous joints

Back 4

1. sutures--only flat bones of skull. CT fibers completely fill in between bones
2. Syndesmosis--bones bound by ord or sheet of fibrous CT
3. Gomhosis--articulation between tthe and bony socket. Teeth fastenend to bone by thing periodontal ligaments

Front 5

Crtilaginous joints

Back 5

bones connected by hyline or firocartilage
1. Synchrondross--bones united b hyaline cartilage(epiphysal disk)
2. Symphysis--articular cartiage attached to fibrocartilage dis (pubis)

Front 6

Synovial joint

Back 6

bones seperated byfluid filled joint cavity
-freely movable
-diarthrodial
include most joints

Front 7

stuctures and materials whch protect bones

Back 7

articular cartilage
articulr discs
synovia fluid
bursae

Front 8

structures which influence oveent capability

Back 8

1. shape of articulting joints.
2. tightness of joint capsule and igaments
3. bulk of adjacent tissue
4. tendons and muscles which cross 2 or more joints

Front 9

structures which influence joint stability

Back 9

tightness of joint capsule and ligaments.
fit of the articulating surfaces
-articular discs
-glenoid and acetabular labrums
-bone shapes

Front 10

Muscular system serves body in 4 ways

Back 10

movement
posture
joint stability
heat production

Front 11

Movement

Back 11

1. locomotion-moving entire body from place to place
2.manipulatio-moving body parts
3. moving materials into ou of within body (respiration, circulation, digestion)

Front 12

Posture

Back 12

1. gravity-costat downward pull
2. opposed-partial contraction of muscles
3. continuously make adjustments to maintain posture
4. called anti-gravity muslces

Front 13

joint stability

Back 13

muscles contribute to joint stability

Front 14

heat production

Back 14

by product of muscle contraction
produce large amount of heat
temperature homeostasis for the body

Front 15

sarcoplemma

Back 15

plama membrane of muscle fiber

Front 16

endomysin

Back 16

thin layer f fine areolr CT
surrounds each mucscle fiber
anchored to sarcolemma

Front 17

endomysin

Back 17

thin layer f fine areolr CT
surrounds each mucscle fiber
anchored to sarcolemma
