p. deficit — a defect of proprioception in which the animal acts as though it does not know where its feet are (in contrast to a cerebellar defect when the feet do not end up where the animal appears to intend that they should go).
p. positioning — positioning of the limbs or head and neck in response to proprioceptive inputs. The basis of postural reflexes.
p. reflex — a reflex that is initiated by stimuli arising from some function of the reflex mechanism itself.
