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
Corpus callosum
Largest body of white matter .
Coronation of right and left sides of the body
Parthway of hearing
Cranial nerve - primary auditory cortex- secondary auditory cortex - brocas
3 parts of brain from development
Midbrain/ hindbrain/forebrain
what is aphasia?
Trouble speaking or with language
Damage to brocas (Generation of speech )
Motor / non flaunt aphasia
. Can understand but can’t respond appropriately e.g tan tan
. Cant compose correct speech
Damage to wernickies area
Sensory/ flaunt aphasia
. Trouble comprehending language but still can speak
How do you test between motor and sensory aphasia
Ask patient to write something down
. Damage to brocas =sensory = not appropriate verbal response but correct written response
. Damage to wernickies = motor = all responses are not placed
Connection aphasia
Damage to arcuate fasculus
. Can make a verbal response however the response dose not fit e.g random
