CNS Topography Flashcards
(32 cards)
Myelecephalon –>
Medulla
Metencephalon –>
Pons, cerebellum
Rhombencephalon –>
Medulla + pons + cerebellum
Mesencephalon –>
Midbrain
Diencephalon =
thalamus, hypothalamus
Telencephalon –>
cerebral cortex, basal ganglia, amygdala, hippocampus
Frontal lobe function:
Intelligence, personality, motivation, motor command
Parietal lobe function:
General sensation, language, spatial orientation
Temporal lobe function:
Hearing, language processing, visual processing, memory
Occipital lobe function:
Vision
Limbic lobe function:
Emotions, basic drives, memory, smell
Hippocampus function:
Limbic component: Spatial memory
Amygdala function:
Limbic component: Associative learning where non-emotional stimuli can acquire emotional properties
Insula function:
Limbic component: Taste, visceral sensation, emotional aspects of pain
Basal ganglia function:
Activates and coordinates internally generated movements
Thalamus function:
Relays sensory and motor information to/from the cerebral cortex
Hypothalamus function:
Integrates autonomic, endocrine, limbic functions
Brainstem functions:
Regulation of cardiac and respiratory function
Regulates CNS
Maintains consciousness
Regulates sleep cycle
Cerebellum functions:
Synergizes and corrects movement
Maintains upright posture
Maintains muscle tone
White matter in spinal cord, medulla, pons and midbrain are on the (inside/outside)
Outside
White matter in the cerebral cortex, cerebellum and diencephalon are on the (inside/outside)
Inside
Somatotopic organization of precentral gyrus of primary motor cortex
Located in:
Hands and face
Frontal lobe
Inferior frontal gyrus contains:
Located in:
Motor speech area (Broca’s area)
Frontal lobe
Somatotopic organization of post central gyrus of primary somatosensory cortex
Located in:
lips, mouth, arms, hands
Parietal lobe
