articulation

site where two or more bones meet

synarthroses

immovable joints

amphiarthroses

slightly movable joint

diarthroses

freely movable joint

fibrous

type of joint that bones are joined by dense fibrous connective tissue

fibrous

type of joint that has no joint cavity

fibrous

type of joint that most are synarthrotic

sutures, syndesmoses, gomphoses

3 types of fibrous joints

sutures

type of fibrous joint that is rigid, interlocking joints containing short connective tissue fibers

sutures

in middle age, these are called synostoses

syndesmoses

type of fibrous joint that bones are connected by ligaments

syndesmoses

type of fibrous joint that movement varies from immovable to slighty movable

gomphoses

type of fibrous joint that is a peg-in-socket joint of teeth in alveolar sockets

cartilaginous joints

bones united by cartilage

cartilaginour

no joint cavity

synchondroses, symphyses

types of cartilaginous joints

synchondroses

type of joint that a bar or plate of hyaline cartilage unites the bones, all are synarthrotic

symphyses

type of joint that hyaline cartilage covers the articulating surfaces and is fused to an intervening pad of fibrocartilage

symphyses

strong, flexible ampiarthroses

synovial

type of joint that all are diarthrotic and include all limb joints

bursae

flattened, fibrous sacs lined with synovial membranes

bursae

contain synovial fluid

tendon sheath

elongated bursa that wraps completely around a tendon

origin

attachment tot he immovable bone

insertion

attachment to the movable bone

nonaxial

slipping movements only

uniaxial

movement in one plane

biaxial

movement in two planes

multiaxial

movement in or around all three planes

gliding

movement of one flat bone surface glides or slips over another similar surface

flexion

decreases the angle of the joint

extension

increases the angle of the joint

hyperextension

excessive extension beyond normal range of motion

abduction

movement away from the midline

adduction

movement toward the midline

rotation

the turning of a bone around its own long axis

supination

turning hand backward

promation

turning hand forward

dorsiflexion

upward movement

plantar flexion

downward movement

inversion

turn sole medially

eversion

turn sole laterally

protraction

anterior movement

retracation

posterior movement

elevation

lifting a body part superiorly

depression

moving a body part inferiorly

opposition of the thumb

movement in the saddle joint so that the thumb touches the tips of the other fingers

plane joints

nonaxial joints, flat articular surfaces, short gliding movements

hinge joints

uniaxial joints, motion along a single plane, flexion and extension only

pivot joints

rounded end of one bone conforms to a "sleeve," or ring of another bone, uniaxial movement only

condyloid joints

biaxial joints, both articular surfaces are oval, permit all angular movement

saddle joints

biaxial, allow greater freedom of movement than condyloid joints, each articular surface has both concave and convex areas

ball and socket joints

multiaxial joints, the most freely moving synovial joints

knee joint

largest, most complex joint of body

femoropatellar joint

plane joint, allows gliding motion during knee flexion

knee joint

at least 12 associated bursae

capsular and extracapsular

help prevent hyperextension

intracapsular ligaments

anterior and posterior curciate ligaments, prevent anterior-posterior displacement

coracohumeral ligament

helps support the weight of the upper limb

three glenohumeral ligaments

somewhat weak anterior reinforcements

hinge

depression and elevation of mandible

sprains

the ligaments are stretched or torn

cartilage tears

due to compression and shear stress

dislocations

occur when bones are forced out of alignment

subluxation

partial dislocation of a joint

arthritis

most widespread crippling disease in the U.S.

gomphosis

A fibrous joint that is a peg-in-socket is called a ________ joint

prevent hyperextension of the knee

The cruciate ligaments of the knee ________.

provide a smooth surface at the ends of synovial joints

amphiarthroses

Articulations permitting only slight degrees of movement are ________

Synchondrose

________ are cartilaginous joints.

plane

The gliding motion of the wrist is accomplished because of the ________ joint

movement of the femur anteriorly and posteriorly are called ________.

yes

are all synovial joints freely movable?

permit essentially no movement

Synarthrotic joints ________.

sutures, syndesmoses, and gomphoses

Fibrous joints are classified as ________.

hyaline cartilage

In symphysis joints the articular surfaces of the bones are covered with ________.
