Neuroanatomy Flashcards
1
Q
frontal lobe
A
- planning and motor movements
- conceptual /intellectual/emotional reasoning
- primary motor cortex in pre-central gyrus
- Broca’s area - motor speech action ( causes Expressive Dysphagia )
2
Q
parietal lobe
A
- processing sensory information
- somatosensory cortex
- espec fine sensation
3
Q
temporal lobe
A
- Language and speech comprehension
- involved in memory formation
- executive memory - frontal lobe involvement
- antrograde memory - short term
- retrograde memory - long term - Wernicke’s area - sensory speech comprehension
( damage causes Receptive Dysphagia ) - Conduction dysphagia
4
Q
expressive dysphagia
A
- damage to broca’s area in the frontal lobe
5
Q
conduction dysphagia
A
- Broca’s and wernicke’s area are connected by the arcuate fasciculus
- damage causes conductive dysphagia
6
Q
receptive dysphagia
A
- damage to the wernicke;s area responsible for sensory speech comprehension
7
Q
occipital lobe
A
- visual processing centre
8
Q
cerebellum
A
- motor control
- movement
- balance + posture
9
Q
anatomy of the hypothalamus
A
- lies on either side of the third ventricle
- lies below the thalamus
- posterior : optic chiasm
- anterior : mid brain
10
Q
functions of the hypothalamus
A
- coordinates with the limbic system to produce ACTH under stressful conditions
- thermoregulation
- thirst and water balance
- cardiac rhythm control via suprachiasmic nucleus
- damage to its mammalian bodies during alcoholism and thymine deficiency causes profound amnesia
