Applied anatomy and physiology Flashcards
Identify two hinge joints on the body.
Elbow and knee
Identify four functions of the skeletal system
Blood production, movement, protection, shape, support, mineral storage
Identify two ball and socket joints on the body.
Hip and shoulder
Which bones meet at the neck and head?
Vertebrae, cranium
Which bones make up the shoulder joint?
Humerus, scapula, clavicle
Which bones make up the knee joint?
Femur, tibia
Which bones make up the elbow joint?
Radius, ulna, Humerus
Which bones make up the ankle joint?
Talus, tibia, fibula
Give an example of a flat bone.
Pelvis, sternum, ribs, cranium, scapula
What is the function of a flat bone.
Protection
Define what is meant by abduction.
Movement of a body part away from the body
Define what is meant by adduction.
Movement of a body part towards the body
Define what is meant by flexion.
Decrease in the angle at a joint
Define what is meant by extension.
Increase in the angle at a joint
Define what is meant by rotation.
Turning a limb along its long axis
Define what is meant by circumduction.
This is where the limb moves in a circle
Give the function of a tendon
Attaches a muscle to a bone
Give the function of a ligament
Attaches bone to bone
Give the function of the joint capsule
Surrounds synovial joints, supports the joint
Give the function of the synovial fluid
Produced by synovial membrane to lubricate the joint
Give the function of the synovial membrane
Produces synovial fluid
Give the function of cartilage
Covers the ends of bones providing smooth, friction free surface
Describe concentric muscle contraction
Where the muscle shortens during contraction
Describe eccentric muscle contraction
When the muscle lengthens during contraction
Which mineral is needed for bone formation?
Calcium
Which movements are performed at hinge joints?
Flexion and extension
Which movements are perofrmed at ball and socket joints?
Flexion, extension, abduction, adduction, rotation, circumduction
Define plantar flexion
Pointing of the foot towards the floor
Define dorsiflexion
Pointing the toes upwards from the floor
What is the function of a long bone?
Movement
What is a joint?
A place where two or more bones meet
