52
describe a saddle joint and give 2 examples
biaxial
movement in 2 planes - reasonable in 1 and less well in another
carpometacarpal thumb joint and sternoclavicular joint
53
describe a pivot joint and give 2 examples
rotary movement around a single axis
eg atlanto-axial and radioulnar
54

posterior to the central compartment
66
where is the thenar space
posterior to the thenar compartment
67
how can deep infections spread from palm to anterior forearm
via the midpalmar space and carpal tunnel
68
