Neuroanatomy Flashcards

1
Q

frontal lobe

A
  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 )

Q

temporal lobe

A
  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

Q

conduction dysphagia

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

Q

functions of the hypothalamus

A
  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
