Articulations/joints Flashcards
condyle
large, round articulating surface or knob
facet
smooth, flat surface for articulation
head
rounded articulation at the end of a bone
articulations
location at which 2 bones make contact that allow movement and provide mechanical support
periosteum
covers all bones until the joint
fibrous
covers the bones at the joint
synovial membrane
secrets synovial fluid into the joint
synovial fluid
is a thick(egg-like) consistency, stringy liquid. nutrient exchange for cartilage. reduces friction. shock absorbsion
synarthorosis
fibrous joint. non-moveable. ie. skull sutures, gomphosis(teeth)
fibrous joint
no synovial joint cavity
amphiarthrosis
slightly moveable, syndesmosis, fibrocartilaginous
synovial joint
it has a synovial cavity
diarthrosis
moveable, gliding joint, hinge joint, pivot joint, condyloid joint, saddle joint, ball and socket joint
gliding joint
uniaxial, z-joint inter-carpal. planar
hinge joint
uniaxial, a concave surface glides around a convex surface allowing for flexion/extension. ginglymus
