Neuroanatomy

Question 1

frontal lobe

Answer 1

1. planning and motor movements
2. conceptual /intellectual/emotional reasoning
3. primary motor cortex in pre-central gyrus
4. Broca’s area - motor speech action ( causes Expressive Dysphagia )

Question 2

parietal lobe

Answer 2

1. processing sensory information
2. somatosensory cortex
3. espec fine sensation

Question 3

temporal lobe

Answer 3

1. Language and speech comprehension
2. involved in memory formation
   - executive memory - frontal lobe involvement
   - antrograde memory - short term
   - retrograde memory - long term
3. Wernicke’s area - sensory speech comprehension
   ( damage causes Receptive Dysphagia )
4. Conduction dysphagia

Question 4

expressive dysphagia

Answer 4

• damage to broca’s area in the frontal lobe

Question 5

conduction dysphagia

Answer 5

1. Broca’s and wernicke’s area are connected by the arcuate fasciculus
   - damage causes conductive dysphagia

Question 6

receptive dysphagia

Answer 6

1. damage to the wernicke;s area responsible for sensory speech comprehension

Question 7

occipital lobe

Answer 7

1. visual processing centre

Question 8

cerebellum

Answer 8

1. motor control
2. movement
3. balance + posture

Question 9

anatomy of the hypothalamus

Answer 9

1. lies on either side of the third ventricle
2. lies below the thalamus
3. posterior : optic chiasm
4. anterior : mid brain

Question 10

functions of the hypothalamus

Answer 10

1. coordinates with the limbic system to produce ACTH under stressful conditions
2. thermoregulation
3. thirst and water balance
4. cardiac rhythm control via suprachiasmic nucleus
5. damage to its mammalian bodies during alcoholism and thymine deficiency causes profound amnesia
