1-Proprioceptive sensations include all the following, except :- 

  1. a- Position sense 
  2. b- Equilibrium sense 
  3. c- Movement sense 
  4. d- kinesthetic sense 

2) Proprioceptors include all the following types of receptors, except :- 

  1. a- muscle spindles 
  2. b- pressure receptors 
  3. c- Vestibular receptors 
  4. d- joint receptors 

3) Proprioceptive sensations are transmitted by all the following pathways,Except :- 

  1. a- Spinothalamic tracts 
  2. b- Spinocerebellar tract 
  3. c- Gracile tract 
  4. d- cuneocerebellar tract 

4) Astereognosis :- 

  1. a- indicates inability to localize the site of touch on the body surface 
  2. b- results from lesions of the secondary somatic sensory area 
  3. c- Associates parietal lobe neglect 
  4. d- results from loss of crude touch sensation 

5)Touch receptors :- 

  1. a- Are found only in the skin 
  2. b- Are all encapsulated receptors 
  3. c- Include two-element receptors 
  4. d- are stimulated by vibration 

6) Tactile receptors include all the following receptors, except :-         

  1. a- free nerve endings 
  2. b- hair follicle receptors 
  3. c- Hair cell receptors 
  4. d- Ruffini nerve endings 

7) Rapidly adapting tactile receptors include all the following types, except :- 

  1.  a- Merkel discs 
  2.  b- Meissner corpuscles 
  3.  c- Pacinian corpuscles 
  4.  d- hair end organs 

8) Fine touch :- 

  1.  a- is detected by slowly adapting touch receptors 
  2.  b- is transmitted by the spinothalamic tract 
  3.  c- is characterized by it emotional affect 
  4.  d- is not involved in feeling the texture of touched objects 

9) Crude touch is more effective than fine touch in evoking an emotional Response because :-

  1. a- Its provoking stimuli are stronger 
  2. b- Its central pathway connects with the limbic system 
  3. c- It is stimulated during emotional excitement 
  4. d- the provoking stimuli have an emotional nature 

10) A more developed two-point   :- 

  1. a- indicates a greater threshold distance for feeling of two points of touch applied simultaneously  
  2. b- is seen in the proximal regions of the body compared with the distal regions 
  3. C-Is inversely related to the size of the receptive fields of the stimulated Sensory units 
  4. D- upon the type of the involved touch receptor
