6. which of the follwoing is not a part of the motor area of the cortex

  • frontal eye field
  • wernickes area
  • pre motor cortex
  • primary motor cortex
  • brocas area

7. which of the following is false in regards to the sensory areas of the cortex

  • primary auditory area found in the temporal lobe next to the lateral sulcus
  • somatosensory cortex produces an understanding of objects by drawing on previous expierence
  • gustatory cortex involved in the perception of smell
  • primary visual cortex found on the posterior tip of the occipital lobe
  • primary somatosensory cortex forund posterior to the central sulcus

8. in regards to the primary motor cortex which is true

  • the homunculi represents the amount and location of cortical tissue devoted to each function
  • motor innervation is ipsilateral
  • controls the precise and involuntary movements of skeletal muscle
  • spinothalamic tract synapses here
  • contains neurons called extra pyramidal cells

9. in regards to white matter of the internal part of the brain which is false

  • association fibres connect different parts of the same hemisphere
  • projection fibres pass through internal capsule
  • projection fibres connect upper and lower parts of the brain
  • the corpus collosum is an example of a route for association fibres
  • commissural fibres connect both hemispheres

10. the corona radiate is where fibres pass through the internal capsule then fan out to reach the cerebellum

  • False
  • True

11. which is false in regards to basal nuclei

  • role show in parkinsons and huntingtons disease
  • the word nuclei is interchangable with ganglia
  • the putamen and globus pallidus make up the corpus striatum
  • made up of caudate nucleus, putamen and globus pallidus
  • complex role in motor control

12. the caudate nucleus lies medial to the third ventricle

  • False
  • True

13. which is false in regards to the diencephalon

  • make up the walls of the fourth ventricle
  • thalamus is part
  • hypothalamus is part
  • epithalamus is part
  • all paired

14. which is true of the thalamus

  • spinocerebellar tract passes through the thalamus
  • unilateral egg shaped nuclei
  • dorsal and spinothalamic 2nd and third order neurons synapse in the thalamus
  • impulses are relayed through the thalamus to the internal capsule to the appropriate part of the motor cortex
  • the epithalamus extends from the superior part of the thalamus

15. which is false of the hypothalamus

  • water balance and thirst
  • involved in endocrine control
  • thermoregulation
  • houses the respiratory centres
  • autonomic contol centre

16. the brain stem which is true

  • crus cerebri house the extra-pyrimidal tracts
  • has grey matter contained in the white matter unlike the spinal cord
  • cranial nerves I-XII arise here
  • consists midbrain and pons
  • borders the third ventricle and the cerebral aquaduct

17. midbrain and pons which is false

  • pons houses cardiovascular centres
  • cerebral punduncles translate to little feet of the cerebrum
  • diencephalon above midbrain pons below
  • contains various nuclei e.g. substantia nigra
  • pontine nuclei are origins of some cranial nerves

18. in regards to the medulla oblongata which is true

  • Vagus nerve arises form the medulla oblongata
  • two posterior ridges (pyramids) formed by the corticospinal tracts
  • corticospinal tracts decussate here
  • contains somatic motor nuclei e.g. cardiovascular centre
  • above the spinal cord directly below the midbrain

19. which is false of the cerebellum

  • damage to the cerebellum results in paralysis
  • compares the bodys performance with higher brain intentions and sends out messages to initiate the appropriate corrective measure
  • dorsal to the pons and medulla
  • smooths and co-ordiantes skeletal muscle contraction to ensure smooth contraction
  • 4th ventricle in front of cerebellum

20. the limbic system which is false

  • involves cerebral and diencephalon structures
  • sometimes known as the emotional brain
  • located on the lateral aspect of each cerebral hemisphere and diencephalon
  • mediates emotional responses
  • involved in the processing of memories
