Joints

Front 1

laceratus fibrosus or bicipital aponeurosis

Back 1

from bicep brachii short and long head tendon of insertion into radial tuberosity, this passes from tendon of insertion to blend w/ fascia covering the muscles on the medial side of the forearm

Front 2

elastic cartilage

Back 2

nose, ear, tubular structures such as auditory eustacian tubes
contains elastin scattered in matrix
flexible

Front 3

hyaline cartilage

Back 3

lines articular surfaces of bones
found in costal cartilages and epiphyseal cartilage of growing bone
mostly type II collagen fibers
resilient, flexible, some rigidity

Front 4

fibrocartilage

Back 4

mostly type I collagen fibers
less ground substance than hyaline b/c so much collagen fibers
found in intervertebral discs and pubic symphysis, menisci of joints, often occurs when tendon and ligament are joined to bones, AC joint

Front 5

synarthrodial joints

Back 5

fibrous joint
not moving, union of two bones by fibrous tissue, no joint cavity
sutures - skull
syndesmosis - contiguous bones connected by interosseous ligament, such as inferior tibiofibular, between radius and ulna

Front 6

syndesmosis

Back 6

fibrous joint, slightly moveable, contiguous bony surfaces united by an interosseous ligament

ex: inferior tibiofibular articulation, between radius and ulna

Front 7

amphiarthrodial

Back 7

cartilagenous joint, slightly moving
joint in which surfaces are connected by fibrocartilage
symphyses - intervertebral discs and pubic symphisis (fibrocartilage)
synchondrosis - ribs and sternum - are made of hyaline(articular cartilage)

Front 8

condyloid

Back 8

cup and saucer, not very deep, oval shaped end of one bone fits into an oval shaped cavity in another bone

ex: wrist joint (between radius and carpals)
joint between metacarpals and phalanges

Front 9

synchondrosis

Back 9

cartilagenouse or amphiarthrodial
made of hyaline cartilage, not moving much

ex: joint between ribs and sternum has hyaline (articular) cartilage

Front 10

hinge joint

Back 10

synovial or diarthrodial joint
allows flexion and extension; convex surface of one bone fits into concave surface of another bone

elbow joint (humeroulnar joint)
knee (between femur and tibia)

Front 11

symphyses

Back 11

amphiarthrodial joint or cartilagenous joint
Much more cartilage present than in a synchondrosis; adjacent bones separated by and fused to a fibrocartilagenous pad

intervertebral discs, pubic symphyses

Front 12

synovial joint

Back 12

diarthrodial
has outer capsule, synovial membrane
space between two articulating bones, has articular cartilage
synovial cavity is small space between articulating bones and filled w/ synovial fluid (lubricates to reduce friction and provide nourishment for the articular cartilage)

Front 13

diarthrodial joints

Back 13

freely movable
also called synovial joints
bathed in synovium

Front 14

pivot joint

Back 14

designed to allow one bone to rotate around the surface of another bone

atlanto-axial joint (turn head)
proximal radioulnar joint (supination, pronation)

Front 15

plane joint

Back 15

also called gliding joint
SC joint
facet joints of spine
costoverterbral joint (ribs)
joint between scapula and clavicle (AC joint?)
between intercarpals and intertarsals

Front 16

enarthrosis

Back 16

ball and socket joint

Front 17

ball and socket join

Back 17

knee, shoulder, synovial joint, diarthrodial

Front 18

saddle joint

Back 18

carpometacarpal joint of thumb (protect during massage) - this is the joint between the trapezium and the first metacarpal
