Anatomy - Musculoskeletal System

Front 1

Synarthroses

Back 1

immovable joints, example suture joints

Front 2

Amphiarthroses

Back 2

slightly moveable joint
example symphysis, between vertebrae

Front 3

Diarthroses

Back 3

most moveable joints, example synovial joint

Front 4

Name three types of joints

Back 4

fibrous, cartilaginous, synovial

Front 5

Fibrous joint definition

Back 5

joint connected by fibrous ligaments only

Front 6

What is the difference between ligament and tendon

Back 6

Ligament connects two bones, tendon connects bone and muscle

Front 7

Name 3 types of fibrous joint

Back 7

suture joint, gomphoses, syndesmoses

Front 8

Describe suture joint

Back 8

type of fibrous joint that connects flat bones of the skull in a tooth like manner

Front 9

what kind of joint in terms of mobility is suture joint

Back 9

synarthroses

Front 10

Describe gomphoses

Back 10

type of fibrous joint that anchors teeth in sockets

Front 11

Syndesmoses

Back 11

apposed bones connected by fibrous membrane, amphiarthroses, radia/ulna, tibia/fibula

Front 12

2 types of cartilaginous joint

Back 12

synchondroses and symphyses

Front 13

synchondroses

Back 13

temporary type of cartilaginous joint seen at growth plate, made of hyaline cartilage, replaced by bone

Front 14

symphyses

Back 14

covered by hyaline cartilage, slightly moveable, ex - pubic symphysis, intervertebral

Front 15

Characteristics of synovial joint

Back 15

diarthroses, hyaline cartilage, joint capsule, synovial lining, capsular ligament, may have disk, fatpad in many, intra articular ligaments in some, freely moveable

Front 16

Name types of articular ligaments

Back 16

capsular, extracapsular, intra articular

Front 17

Capsular ligament

Back 17

thickening of articular capsule, inside joint

Front 18

extracapsular ligament

Back 18

outside and distinct from capsule

Front 19

Intra articular ligament

Back 19

appear to be within synovial membrane but actually outside joint cavity
example - acl/pcl

Front 20

Name 6 types of synovial joints

Back 20

pivot, ball and socket, condyloid, hinge, plain, saddle

Front 21

Plane syn joint

Back 21

allows gliding and sliding, uniaxial, between fingers

Front 22

Hinge syn joint

Back 22

allows flexion and extension, uniaxial
ex - elbow, knee

Front 23

Pivot joint

Back 23

allows rotation. like shaking head
example atlantoaxial joint

Front 24

Condyloid joint

Back 24

allows flexion, extension, abduction, adduction and circumduction, no rotation, biaxial, example wrist, finger movement

Front 25

Saddle joint

Back 25

saddle like heads allows rotation in two planes, biaxial example carpometacarpal joint of the thumb

Front 26

Ball and socket

Back 26

allows most movement in many axes, hip

Front 27

Joints blood supply

Back 27

Joints are relatively poorly supplied with blood vessels. In general, the blood supply comes from collateral branches of larger vessels. Many joints are surrounded by systems of anastomoses that allow blood flow around the joint regardless of the position of the limb

Front 28

Joints nerve supply

Back 28

highly innervated, capsule especially, nerves supplying joint also supply muscle moving that joint and skin covering joint
