10 Joints Flashcards
how are the joints classified
function and structure
what are the two types of fibrous joints and what do they connect
sutures - cranial and facial bones
sydesmoses - distal articulation of the tibia and fibula
what tissue is present in fibrous joints
dense fibrous connective tissue
are fibrous joints immovable or movable
immovable
what are the two types of cartilaginous joints and what tissues connect them
synchondroses - hyaline cartilage
symphyses - fibrocartilage
what are the two types of cartilaginous joints called when they are present in adults
synchondroses - synarthoses
symphyses - amphiarthroses
where are synchondroses found
costal cartilage of rib 1
manubrium
epiphyseal plates
where are symphyses found
intervertebral discs between the bodies of vertebrae
pubic symphysis
are cartilaginous joints immovable or movable
immovable
what is not present in fibrous joints and cartilaginous joints
a joint cavity
are synovial joints immovable or moveable
movable, diarthroses
do synovial joints have a joint cavity
yes
what limits the movement of synovial joints
ligaments, muscles, tendons, or a joining bones
what encloses the joint cavity
the articular capsule
what makes up the articular capsule
the synovial membrane and the fibrous capsule
what is the function of the synovial membrane
secretes synovial fluid
what is the function of synovial fluid
lubricates the joint and provides nourishment for the articular cartilage
what are the six categories of synovial joints
plane/gliding joints hinge joints pivot joints condyloid/ellipsoid joints saddle joints ball and socket joints
Where are plane/gliding joints located? what type of movement do they allow?
bones of wrist and ankle, sternum and ribs, vertebrae and ribs, clavicle and scapula
nonaxial - only slight movement
where are hinge joints located? what type of movement do they allow?
elbow, phalanges, ankle, knee
monaxial - movement occurs around a single axis
where are pivot joints located? what type of movement do they allow?
atlas and axis, head of the radius and ulna
monaxial - movement occurs around a single axis
where are condyloid/ellipsoid joints located? what type of movement do they allow?
radius and carpal, occiptal and atlas, metacarpalphalngeal, and metatarsophalengeal joints
biaxial - movement occurs around two axes
where are saddle joints located? what type of movement do they allow?
joint between carpal and metacarpal bones of thumb
biaxial - movement occurs on 2 axis
where are ball and socket joints located? what type of movement do they allow?
shoulder, hip
multiaxial - movement occurs in all axes and planes
