Applied anatomy and physiology Flashcards
List the functions of the skeleton
- support
- protection
- movement
- structural shape and points for attachment
- mineral storage
- blood cell production
List 5 parts of a synovial joint
- joint cavity containing synovial fluid
- cartilage
- bone
- synovial membrane
- capsule
what does the cartilage do
- covers the ends of bones
- provides a friction free surface
what does the synovial fluid do
lubricates the joint
what is the capsule
- tough fibrous tissue
- surround the synovial joint, usually supported by ligaments
what do ligaments do
link bone to bone
what is a dislocation
when the bones of a joint separate from their normal position
what is the bursae
a fluid-filled bag that helps reduce friction in a joint
what to tendons do
tie bone to muscle
what does the synovial membrane do
creates the synovial fluid
what is a hinge joint
a joint that allows flexion and extension
what is flexion
movement where angle between bones increases
what is extension
movement where angle between bones increases
what are vertebrae
bones that form the spine or backbone
what is abduction
movement where limbs are moved away from the body
what is adduction
movement where limbs are moved back towards the body
what is rotation
turning a limb along its axis
what is meniscus
cartilage acting as a shock absorber between the tibia and femur in the knee joint
what does the cruciate ligament do
attaches the tibia to the femur in the knee joint
what is plantar flexion
movement at ankle where the toes are pointed towards the ground (action of a calf raise)
what is dorsiflexion
movement at ankle where the toes are pulled towards the knee
