Neuro 3

• Inflammation of the brain

  Encephalitis
• Primitive name of the brain

  Encephalon
• Inflammation of the meninges

  Meningitis
• Main division of the brain

  1. Prosencephalon
  2. Mesencephalon
  3. Rhombencephalon
• Prosencephalon aka

  Forebrain
• Mesencephalon aka

  midbrain
• Rhombencephalon

  Hindbrain
• Sub division of Prosencephalon

  • Telencephalon
  • Diencephalon
• Mesencephalon subdivision

  Mesencephalon
• Rhombencephalon division

  • Metencephalon
  • Myelencephalon
• Telencephalon adult derivatives

  • Cerebrum
  • Basal Ganglia
  • Hippocampus
• Cavities of

  • Cerebrum
  • Basal Ganglia
  • Hippocampus

  Lateral Ventricles
• Diencephalon adult derivatives

  • Subthalamus
  • Hypothalamus
  • Epithalamus
  • Thalamus
  • Pineal body
  • Infundibulum
• Diencephalon (SHET+PI) cavities

  Third ventricles
• Mesencephalon adult derivatives

  • Tectum
  • Cerebral pedicles (Crus cerebri+ Tegmentum)
• Mesencephalon cavity

  Aqueduct of Sylvius
• Metencephalon adult derivatives

  • Cerebellum
  • Pons
• Myelencephalon adult derivative

  Medulla Oblongata
• Metencephalon and Myelencephalon cavity

  Fourth ventricles
• Largest part of diencephalon

  Thalamus
• Structural abnormality of the subthalamus

  Hemiballismus
• continuation of the tectum in the spinal cord; for head turning during visual and auditory reflexes

  Tectospinal tract
• short tube that connects the 3rd and 4th ventricles

  Aqueduct of Sylvius
• Cerebrum aka

  Big brain
• Cerebrum has how many hemisphere

  2
• LEFT hemisphere

  • Dominant
  • Language
  • Mathematical
  • Analytical
• RIGHT hemisphere

  Non-dominant

  Arts and music

  Insight and judgement

  Memory
• Clinical correlation of L hemisphere

  • Aphasia
  • Acalculia
  • Ideomotor apraxia
  • Ideational apraxia
• Clinical correlation of R hemisphere

  • Hemineglect
  • Dressing Apraxia
  • Constructional Apraxia
• ‼️ Important

  Broca's and Wernicke's area are ONLY found on the LEFT side of the brain because LEFT HEMISPHERE is for La-la-la-LANGUGAE
• 7 Types of Aphasia

  1. Wernicke's aphasia
  2. Broca's aphasia
  3. Global aphasia
  4. Anomic aphasia
  5. Conduction aphasia
  6. Transcortical Motor aphasia
  7. Pure word deafness
• Gertsman syndrome affects what BA?

  Area 39,
• BA 39

  Angular Gyrus
• Manifestation

  • L/R disorientation
  • Finger agnosia
  • Agraphia
  • Acalculia

  Gertsmann Syndrome
• Folds, convolution, rounded elevations

  Gyrus
• Grooves or furrows

  Sulcus
• a deeper furrow

  Fissure
• Separates the right and left hemisphere

  Median Longitudinal Fissure
• Sweeps backward from the temporal pole to separate the temporal lobe from the other lobes

  Lateral Sylvian Fissure/ Lateral Sulcus
• Separates frontal and parietal lobes of the brain

  Rolandic Fissure/ Central Sulcus of Rolando
