2. which statement about the nervous system is NOT true?

  • grey matter contains the cell bodies and dendrites of neurones
  • each cerebral hemisphere is divided into 4 lobes
  • each spinal segment gives rise to two pairs of spinal roots
  • the white and grey matter of the spinal cord is arranged in the same way as that in the cerebral hemispheres
  • the dorsal root ganglia contains the cell bodies of the primary sensory neurones

3. which of the following is an important functional parameter of pain receptors?

  • exhibit little or no adaption
  • are not affected by muscle tension
  • signal only flexion reflex at joint capsules
  • can be inhibited voluntarily
  • give rise to signals that convey the location of a joint

4. concerning the motor cortex:

  • motor areas of the cortex receive somatosensory inputs via the thalamus
  • the coticospinal tract provides the connection between the motor cortical areas and the spinal cord
  • following a cerebral haemorrhage affecting the precentral gyrus of the right hemisphere, the patient feels no sensation on the left side of the body
  • the motor cortex is situated in the postcentral gyrus
  • the motor cortex is in the parietal lobe

5. regarding receptors in the skin:

  • the nociceptors of the skin are bare nerve endings
  • all sensory info from the skin reaches the brain via the dorsal column of the spinal cord
  • all skin receptors are encapsulated
  • the receptive fields of touch receptors are uniform is all skin areas
  • all sensory info from the skin reaches the brain via the ventral column of the spinal cord
