synovial cavity
space between articulating bones is called _____
synovial cavity, c.t., fibrous, cartilaginous, synovial
structural classification of joints 1. presence or the absence of ________ 2 the type of ____ that holds the bones together. 3 types of structural classification of joints, ___________
fibrous joint, sutures,interosseous membranes syndesmosis
joint with no synovial cavity, bones are held together by dense irregular ct , this joint permits little or no movement. there are 3 types _________
cartilaginous, symphyses and synchondroses
joint with no synovial cavity, bones are held together with cartilage ( hyaline or fibrocartilage) is _______ there are 2 types ______
synovial joints , diarthrosis
a joint with the presence of space between bones known as __________. all synovial joints are classified as ______
degree of movement, synarthrosis- immovable, amphiarthrosis- slightly moveable , diarthrosis- freely moveable
joints are functionally classified by their _________ there are 3 types ________
synovial joints
diarthrosis joints are joints that are freely moveable and the only joints within this classification Are the ________
diarthrosis
all synovial okints are functionally classified as _____
immoveable
synarthrosis is a joint that is _____
slightly moveable
amphiarthrosis is a joint that is
freely moveable
diarthrosis is a joint that is
1 suture. 2. gomphosis. 3. synchondrosis. 4. synostosis
4 types of joints falling under the functional classification of synarthrosis
1. syndesmosis. 2. symphysis
2 types of joints falling under the functional classifications of amphiarthrosis
gliding, hinge, pivot,ellipsoidal-condyloid,saddle,ball and socket
6 type of joint falls under the functional classification of diarthrosis.

a cartilaginous joint with hyaline cartilage as the connective tissue is ______ it is functionally classified as ______it is found in the
synostosis, synarthrosis, frontal bone grows in halves that join together by age 6
a suture present in childhood that is replaced with bone in An adult is __________ the functional classification is ________ example. is that the ____________
syndesmosis, amphiarthrosis, distal tibiafibular joint
a fibrous joint where there is greater distance between articulating surfaces and more dense irregular tissue than in a suture is _-------------' it is functionally classified as ___________ and is located in the
symphysis, amphiarthrosis, pubic symphises, junction of the manubrium and body of sternum,intervertebral joints
a cartilaginous joint where the ends of bones are covered with hyaline but a broad flat disc of fibrocartilage connects the bones is _______ it is classified functionally as ________ and is found in ________
synovial, long bones where articular cartilage is present
diarthrosis joints are freely moveable joints they are _______ joints. they can be found in the __________
mono axial, pivot hinge
_________ diarthrosis allows motion around a single axis , such as ____ and ____ joints
biaxial, conyloid or ellipsoidal
______ allows motion around 2 axis. such as -----------_ joints
triaxial, saddle. ball and socket
______ allow motion around 3 axis such as. ____ and ___ joints
flexion and extension , flexion and extension and abbductionband addiction, flexion and extension, abduction and addiction and rotation
mono axial joint only allow ______ movement biaxial joint allows ______ and ____ movement triaxial joints allow _____ , ______ and ______ movement
gliding joints, intertarsals and intercarpals
simple movement of flat bones , moving back and forth and size to side , limited range of motion, is what type of diarthrosis_________, these joints are found in ______
hinge, flexion nd distention, knee, elbow ankle
a joint where the concave surface of one bone fits into the convex surface of another bone is a ________ this joint permits only ______ being mono axial , and is found in the ______
pivot, mono axial, radioulnar and atlantoaxial
a jont where a rounded or pointed surface of one bone articulates with a ring formed partly by another bone and partly by a ligament. this joint allows only extension and flexion so it is a ______ joint. examples are _________
ellipsoidal,flexion and distention and abduction and addiction, wrist and metacarpalphalangeal joints 1- v
a joint where the convex oval shape of one bone fits into oval shaped depression of another is ________ this joint is biaxial allowing__________ and _____ movement examples are the _________ and _____
saddle, triaxial, carpometacarpal
a joint where an articular surface of one bone is saddle shaped and the surface of another bone fits into the saddle, _______ this joint is ______ and includes the joint bw the thumb and the trapezium called ______
ball and socket, acetabulum , glenoid cavity of the scapula, glenohumeral,
a joint where a ball like surface of one bone fits into the cup like depression of another bone________some examples are the femur sits in the _____and the humerus sits in the ____
1 surrounds synovial joint, 2 encloses synovial cavity,3 unites articulating bones
3 important parts functions of articular capsule
outer fibrous, inner synovial membrane
name the 2 layers of the articular capsule
periosteum
the outer fibrous layer of articular capsule attaches to the ______ of articulating bones
1. subdivide the synovial cavity allowing separate movements in each cavity, 2 allow 2 bones of different sizes to fit together more tightly 3. helps maintain stability of joint

bursae, shoulder or knee
sac like structure found in some joints to reduce friction is ______ such as ____
