A 3 CNS Topography Flashcards
Supramarginal gyrus and angular gyrus function?
Language processing
See pic, these are posterior to postcentral gyrus. Think sensory & processing language.
Post-central gyrus function?
Primary somatosensory
Pre-central gyrus function?
Primary motor
Broca’s function?
Speech
See pic, is ant. to pre-central gyrus. Think motor & speaking.
Temporal function?
Hearing, language, visual, memory
- -Transverse temporal gyrus=primary auditory cortex
- -Superior temporal gyrus=has Wernicke’s area (speech understanding)
Occipital function?
vision
Limbic components?
- Cingulate gyrus & Isthmus
- Parahippocampal gyrus
- Uncus
Limbic function?
Emotion, basic drives, smell, memory
Insula function?
Taste, emotional aspect of pain,visual & auditory, visceral sensation
Hippocampus function?
Spatial memory
Amygdala function?
Associating emotion w/ non-emotional stimuli
Basal ganglia function?
Coordination/ Refining of movement
Thalamus function?
Relay board for sensory & motor
Hypothalamus function?
Integrates autonomic, endocrine, limbic functions
Midbrain function?
- Sup. colliculus: eye movement reflexes (like turning toward flash of light)
- Inf. colliculus: relay in auditory path
- CN 3, 4 (nuclei)
Pons function?
-CN 5,6,7 (nuclei)
Medulla function?
- Pyramids (voluntary motor)
- CN 8-12 (nuclei)
Cerebellum function?
-Refine/ coordinate/ remember movement
Parietal lobe function?
Sensation
Language
Spacial orientation
What is the function of the insular lobe?
Taste
Visceral sensation
Emotional aspect of pain
What is the function of the epithalamus?
Circadian rhythm
Which CN nuclei lie in the midbrain?
CN 3&4
Which 2 structures should we know that Are in the periostial layer of the dura matter?
Sensory meningeal nerves (trigeminal)
Middle meningeal artery
Which layer forms the dural Venus sinuses? What about the falx cerebri and tentorum cerabelli?
The meningeal layer of the dura
Same.
T/F the arachnoid matter is avascular?
True
Dentriculate ligaments and the terminal filum are formed by what?
Pia matter
