Nervous System brain 🧠 Flashcards
Name the four lobes
.temporal lobe
. Frontal lobe
. Parietal lobe
. Occipital lobe
Name the three main cortex’s
. Frontal association cortex
. Temporal association cortex
. Parietal association cortex
What is the function of Exeter’s area
.planning hand movement e.g handwriting
The pre motor cortex
Planning
What is the function of the Brocas
.Scanning
.reading
.planning
Controls movement of the trachea, mouth, nose, eyes, face futures, hands, arms,shoulders, and back ( homunculus ). Also is responsible for the activation of muscles and therefore have large 🔼 shaped cells that allow AP to propagate down to the furthest regions of the body.
Pre central gyrus
Or
Primary motor cortex
The primary sensory cortex made of many small receiving neurones called granular cells.
Post central gyrus
Or
Primary sensory cortex
Function of the superamarginal gyrus.
Reading
Function of the angular gyrus.
Writing ✍️
What are the two cortex’s that are involved in vision
The primary visual cortex (what we actually see) and the secondary visual cortex (magic tricks )
The pre occipital notch is before the
Occipital lobe ???
The primary auditory cortex
.hearing
. Tone
.time
Tonotopic
What is meant by tonotopic
Is the import of different tones.
the spatial arrangement of where sound is perceived, transmitted, or received.
wernicke’s area / secondary auditory cortex.
Language
Verbal cues -tuning out white noise
Converts tones and time to language
Frontal association cortex = 7
.intelligence . Personality . Behaviours . Mood . Cognitive function . Morals .fight or flight
Parietal association cortex = 6
. Spatial skills .3D recognition - shapes - faces - concepts - Abstract perception
Temporal association cortex =4
.memory
.mood
. Aggression
. Intelligence
Non dominant hemisphere (right ) = 5
. Non verbal language e.g body language . emotional expression/ tone of language . Spatial skills/3D . conceptual understanding . artistic/musical skill
What are the effects of injury on the brain 🧠
. Loss of non verbal language . Speech lacks emotion . Spatial disorientation . Inability to recognise familiar objects . Loss of musical appreciation
What is the primary function of the arcuate fasciculus?
to align speech recognition /comprehension with speech production.
What is the major symptom of a person with a non-fluent aphasia?
Inability to coordinate muscular movements for generating speech
Arcuate fascicules
White matter pathways from wernickes to brocas
If a patient can not write
Sensory aphasia
Cingulate gyrus
Relays info toaster example
Flight or flight
