Muscles and bones Flashcards
Ligaments
connects bone to bone
Articular cartilage
tissue that covers the joint surface- allows shock
Synovial fluid
reduces friction
Joint capsule
secrets synovial fluid- strengthens the joint
Pivot joint
radius-ulnar joint
Gliding joint
wrist joint- motion in two places
Condyloid joint
wrist joint similar to ball and socket
Circumduction
limb goes in a circular motion e.g bowling
Horizontal flextion/ extension
limb moves forwards/ backwards from the body
Frontal plane of movement
front and back (abduction + adduction)
Sagittal plane of movement
Divides body into left and right (flexion + extension)
Transverse plane of movement
Divides body into upper and lower (horizontal flexion + extension)
Hip flexion
Agonist: Iliopas
Antagonist: Gluteus max
Hip adductor
Agonist: adductor longus
Antagonist: gluteus medius
Hip medial rotation
Agonist: gluteus minimus
Antagonist: gluteus max
