Joints Flashcards
all sutures are what type of joint
fibrous
sutures
fibrous joints between cranial bones
joint between the tooth and the socket
gomphosis (fibrous joint)
intervertebral disks are considered primary or secondary
fibrous cartilage found in secondary cartilaginous joint
epiphyseal plate is primary or secondary
hyaline cartilage found in primary epiphyseal plate
synovial membrane
fluid contains nutrients to feed the cartilage
perichondrium
fibrous connective tissue around the cartilage (except articular cartilage) to provide nutrients
articular cartilage does not have a perichondrium
has to be smooth, cannot be rough with fibrous cartilage such as perichondrium
long head of the biceps originates from
supraglenoid tubercle
short head of the biceps originates from
coracoid process
shape of the bone plays major role in
movement or mobility of the joint
movement at a joint is affected by
shape of the condyles, ligaments and soft tissue
diarthrotic joints are always
synovial joints
supination and pronation
radioulnar
arthro
joint
syn
together
amphi
slight
dia
through
chondro
cartilaginous
synarthrosis
no movement
amphiarthrosis
slight movement
diarthrosis
freely movable
Two classifications of joints
structural
functional
structural classification of joints is based on
type of tissue between the bones
tissue types of structural joints
fibrous
cartilaginous
synovial
functional classification of joints is based on
amount of movement
movement in functional joints has three classifications
synarthrosis (no)
amphiarthrosis (slight)
diarthrosis (free)
sutures, gomphosis, syndesmosis are classified as
structural, fibrous
epiphyseal plate and 1st rib/sternum are classified as
structural, cartilaginous
symphysis is classified as
structural, cartilaginous
diarthtrotic joints are classified as
structural, synovial
sutures
fibrous collagen fibers between the plates of the skull
syndesmosis
fibrous collagen fibers between tibia and fibular
gomphosis
fibrous tissue around the root of the tooth
synostosis
ossification of sutures in the skull
two types of cartilaginous joints (structural)
primary
secondary
six types (varieties) of synovial joints (structural)
plane condyloid hinge saddle ball and socket pivot
three examples of cartilaginous joints (secondary)
costochondral
symphyses
intervertebral discs
secondary cartilaginous joints are made from what type of cartilage
fibrous
two examples of cartilaginous joints (primary)
epiphyseal plate
1st rib & sternum
primary cartilaginous joints are permanent or temporary
temporary
primary cartilaginous joints are made from what type of cartilage
hyaline cartilage
epiphyseal plate and 1st rib/sternum are made from what type of cartilage
hyaline
costochondral joints, symphyses pubis, intervertebral discs are made from what type of cartilage
fibrous
type of joint that contains a fibrous capsule, synovial membrane, and synovial fluid
synovial joint
fibrous capsule of synovial joint is made of what type of tissue
dense irregular connective tissue
synovial membrane of synovial joint is made of what type of tissue
aerolar connective tissue
slippery, reduces friction and is composed of proteoglycans (hyaluronic acid)
synovial fluid
bursae can be found
tendons and ligaments rub against bone
bursa that extends along a tendon for some distance
tendon sheath
fluid inside bursea membrane
synovial fluid
diarthrotic joints are all considered
synovial joints (not all synovial joints are diarthrotic)
movement of a joint is affected by what three things
soft tissue
shapes of condyles
ligaments
example of synovial joint (plane)
acromioclavicular joint
example of synovial joint (condyloid)
metacarpophalangeal joint
example of synovial joint (hinge)
elbow joint
example of synovial joint (saddle)
carpometacarpal joint
example of synovial joint (ball and socket)
hip and shoulder joint
example of synovial joint (pivot)
atlanto-axial joint
atlanto-axial joint has what type of range of motion
uniaxial
three immovable joints (synarthrotic)
epiphyseal plate
gomphosis
sutures/synotoses
two joints with little movement (amphidiathrotic)
symphysis
syndesmosis
freely movable joints (diarthrotic)
all synovial joints
four types of ranges of motions
nonaxial
uniaxial
biaxial
traxial (multiaxial)
describe nonaxial movement
slipping, gliding; very little movement
describe uniaxial movement
movement in one plane; permits rotation
describe biaxial movement
movement in two planes;
describe trixial movement
movement in or around all three planes
types of gliding joints (4)
intercarpal
intertarsal
acromioclavical
sacroilliac
types of pivot joints (2)
C1/C2
radio-ulnar (proximal)
types of hinge joints (4)
elbow
knee
ankle
interphalangeal
hinge joints allow what type of movements (2)
angular motion in a single plane
flexion/extension
ball & socket joints (2)
shoulder and hip
ball & socket joints allow what types of movements (4)
flexion/extension
adduction/abduction
rotation
circumduction
biaxial joints (2)
condyloid (elipsoid)
saddle
triaxial joints (1)
ball & socket
uniaxial joints (2)
pivot
hinge
pivot joints allow what type of movement (1)
rotation
gliding joints allow what type of movement
flat surfaces to slide across one another
condyloid (elipsoid) joints allow what type of movement (3)
flexion/extension
abduction/adduction
circumduction
saddle joints allow what type of movement (4)
flexion/extension
abduction/adduction
circumduction
opposition
types of saddle joints
thumb (1st carpophalengeal)
muscles that stabilize the rotator cuff
(SITS) subscapularis inferaspinatus teres minor supraspinatus
sprains involve
ligaments
dislocations involve
articulating surfaces
two classes of joints
functional
structural
varieties of fibrous joints
