joints Flashcards
fixed or immovable joints are also called
fibrous joints
fixed joints
these bones cannot move at all and are found in the cranium
slightly movable joints are also called
cartilaginous joints
freely movable joints are also called
synovial joints
slightly movable joints
bones can move a small amount as they’re linked together with ligaments and cartilage
example of cartilaginous bones
vertebrae and ribs
synovial joints
have greater amount of movement and have an number of parts
what are the synovial joints in he body
elbow, shoulder, knee and hip
what does synovial fluid in the synovial joint do
it lubricates the joint so it moves slowly
what does the synovial membrane do
produces synovial fluid
what does the cartilage at the end of the bones do
cushions the joints and prevents friction and wear between the bone ends
what does the joint capsule do
prevents wear and tear on the bones
what are bones connected by
ligaments
muscles are connected by
tendons
examples of ball and socket joints
hip and shoulder
do ball and socket joints have a lot of movement
They have the greatest range of movement allowing movement in almost every direction.
hinge joints example
elbow and knee
range of movements for hinge joints
allow you to move the elbow or knee in only one direction
flexion
bending a limb at a joint
extension
straightening a limb at a joint
abduction
movement of limbs sideways away from centre of the body
adduction
movement of limb sideways towards the body
dorsiflexion.
movement of foot at the ankle joint to pull toes towards shin
plantar-flexion
movement of foot at ankle joint to point toes away from shin
rotation
circular movement around joint
circumduction
movement allowing 360 degrees range of movement
