synostosis

fusion of 3 coxal bones

bony fusion

fusion of the frontal bone

rheumatism

general term indicating pain and stiffness affecting the skeletal system

synathrosis

immoveable joints

articulation

joint

ellipsoid joint

joint where an oval articular face nestles within a depression on the opposing surface

ball- and- socket joint

joint where the round head of one bone resets within a cup-shaped depression in another

saddle joint

joints that have complex articular faces, they are concave on one axis and convex on the other axis

gliding joint

joints that have fattened or slightly curves surfaces that slide across one another, amount of movement is slight

syndesmosis

ligaments that connect 2 bones but limit their motion

linear movements

two bones gliding past each other ex. carpal/ carpal

synovial joint

ball- and- socket joints and hinge joints

synchondrosis

binds the diaphysis to the epiphysis

symphysis

bones are separated by a wedge or pad of cartilage

sutures

bones interlocked together

angular motion

changes the angle between the shaft and the articular surface, ex. abduction/ adduction

arthritis

damage to the articular cartilages, encompasses the rheumatic diseases that affect synovial joints

synovial fluid

lubricates he surfaces of the articular cartilages and reduces friction, acts as shock absorber

structure (of a joint)

makeup of the joint

flexion

movement in the anterior- posterior plane that reduces the angle between articulating elements

circumduction movements

moving the joint in a circular manner

intervertebral discs

pads of cartilage between the vertebral bodies of adjacent vertebrae

menisci

pads of fibrous cartilage that may subdivide a synovial cavity, channel the flow of synovial fluid, allow for variations of shape of the articular surfaces, and restricts movement

gomphosis

periodontal ligaments of the teeth

hinge joint

permit angular motion in a single plane

hinge joints

permit angular movement in a single plane, a non axial joint

pivot joint

permits rotation only

cartilaginous joint

pubic symphysis

anatomical design

range and function of a joint depend on__________

function (of a joint)

range of motion of a joint

fibrous joint

skull sutures

amphiarthrosis

slightly moveable joints

musculoskeletal system

the system that the muscular and skeletal systems make up

diathrosis or synovial joints

the type of joint specialized for movement and has a wide range of motion
