Q

why is palpation important?

A
  1. It allows us to find out the existence of disease

  3. it allows to find out the local temperature
  4. it allows us to find out the existence of pathological mass
  5. it allows to find out the location, size, shape, consistency of the discovered mass, its relation to the surrounding organs, motility, and its movement during breathing
