6. which of the follwoing is not a part of the motor area of the cortex
- pre motor cortex
- primary motor cortex
- wernickes area
- brocas area
- frontal eye field
7. which of the following is false in regards to the sensory areas of the cortex
- somatosensory cortex produces an understanding of objects by drawing on previous expierence
- primary visual cortex found on the posterior tip of the occipital lobe
- primary somatosensory cortex forund posterior to the central sulcus
- gustatory cortex involved in the perception of smell
- primary auditory area found in the temporal lobe next to the lateral sulcus
8. in regards to the primary motor cortex which is true
- spinothalamic tract synapses here
- the homunculi represents the amount and location of cortical tissue devoted to each function
- motor innervation is ipsilateral
- contains neurons called extra pyramidal cells
- controls the precise and involuntary movements of skeletal muscle
9. in regards to white matter of the internal part of the brain which is false
- projection fibres pass through internal capsule
- association fibres connect different parts of the same hemisphere
- commissural fibres connect both hemispheres
- the corpus collosum is an example of a route for association fibres
- projection fibres connect upper and lower parts of the brain
10. the corona radiate is where fibres pass through the internal capsule then fan out to reach the cerebellum
11. which is false in regards to basal nuclei
- complex role in motor control
- the putamen and globus pallidus make up the corpus striatum
- made up of caudate nucleus, putamen and globus pallidus
- role show in parkinsons and huntingtons disease
- the word nuclei is interchangable with ganglia
12. the caudate nucleus lies medial to the third ventricle
13. which is false in regards to the diencephalon
- hypothalamus is part
- epithalamus is part
- all paired
- make up the walls of the fourth ventricle
- thalamus is part
14. which is true of the thalamus
- dorsal and spinothalamic 2nd and third order neurons synapse in the thalamus
- the epithalamus extends from the superior part of the thalamus
- impulses are relayed through the thalamus to the internal capsule to the appropriate part of the motor cortex
- unilateral egg shaped nuclei
- spinocerebellar tract passes through the thalamus
15. which is false of the hypothalamus
- thermoregulation
- involved in endocrine control
- houses the respiratory centres
- water balance and thirst
- autonomic contol centre
16. the brain stem which is true
- crus cerebri house the extra-pyrimidal tracts
- consists midbrain and pons
- has grey matter contained in the white matter unlike the spinal cord
- cranial nerves I-XII arise here
- borders the third ventricle and the cerebral aquaduct
17. midbrain and pons which is false
- contains various nuclei e.g. substantia nigra
- diencephalon above midbrain pons below
- cerebral punduncles translate to little feet of the cerebrum
- pons houses cardiovascular centres
- 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
- above the spinal cord directly below the midbrain
- corticospinal tracts decussate here
- two posterior ridges (pyramids) formed by the corticospinal tracts
- contains somatic motor nuclei e.g. cardiovascular centre
19. which is false of the cerebellum
- compares the bodys performance with higher brain intentions and sends out messages to initiate the appropriate corrective measure
- dorsal to the pons and medulla
- damage to the cerebellum results in paralysis
- smooths and co-ordiantes skeletal muscle contraction to ensure smooth contraction
- 4th ventricle in front of cerebellum
20. the limbic system which is false
- involved in the processing of memories
- located on the lateral aspect of each cerebral hemisphere and diencephalon
- involves cerebral and diencephalon structures
- sometimes known as the emotional brain
- mediates emotional responses
