  1. Eye movement due to contraction of superior rectus muscle is directly antagonised by:




    A. musculus obliquus superior bulbi
  2. Fast adaptation of tactile receptors is caused by:




    C. decrease of firing rate despite the ongoing depression of the receptor
  3. Unilateral injection of cold water into the outer ear causes vertigo and nausea. The basic cause of this phenomenon is:




    C. cooling-induced flow ot the endolymph
  4. Which one of the following physiological mechanisms happens when the auditory system detects the increase of tone pitch?




    A. the largest amplitude of vibrations of the basilar membrane will shift towards the base of the cochlea.
  5. The stimulation of the Golgi tendon organ leads to:




    E. reflex inhibition of motonenurones
  6. Which one of the following receptor types display, under normal physiological conditions, the greatest degree of adaptation?




    D. tactile receptors
  7. Visceral pain:




    B. is a subjective feeling, unpleasant sensory and emotional experience, related to either actual or potential damage.
