Nervous system Flashcards
What is the function of the arcuate fasciculus
It is the connection from Wernicke’s to Broca’s area - it connects the understand speech to the “making speech” or speech production
What is the precentral gyrus/primary motor cortex
This is the area in the brain that executes movement. It has a representation of the body in an orderly way - homonculus and has a representation of:
- throat
- mouth
- eyes
- nose
- back
- buttocks
- legs (this extends into the medial view of the brain)
Before the execution of movement, what needs to happen in the brain?
Before the execution of movement (in the primary motor cortex), there needs to be some sort of planning to do - this happens in the planning cortex that co-ordinates what muscles needs to be activated before actually executing the action
What areas are found in the planning cortex?
Broca and Exner’s area
What is the function of Broca’s area?
Broca’s area is responsible for speech production or the planning of speech.
What is the function of Exner’s area?
Exner’s area is what plans the hand and is responsible for writing
What is the supramarginal and angular gyrus responsible for?
Main functions are for reading and writing. They help us to interpret what we are reading and also plans eye movement - like when little kids are learning to read, they put their finger under the word to make sure they stay focused.
What is the function of the Post-central Gyrus/sensory cortex and where can you find it?
It is just after the central sulcus.
It relates to sensing what is going on in different parts of the body and registers pain e.g. if you have a sore thumb
What is the function of Wernicke’s area?
Wernicke’s area is responsible for understanding speech. It takes the tone/timing/pitch and puts them together so that we can understand.
What is the function of the primary auditory cortex?
It receives input from the cochlea in the ear and deals with time and tone manner - it is arranged tonotopically.
What is the mnemonic for Frontal association cortex?

Aphasia in Wernicke’s area?
Sensory aphasia or Fluent aphasia
Cant understand the question
Aphasia in Broca’s area?
Motor aphasia or Non-fluent aphasia
Can understand the question, however cannot respond but could give a thumbs up
Connectional Aphasia?
Aphasia in the Arcuate Fasciculus
No relevance to the question asked
What happens when an instruction is received through the ear, the tones are broken down and we need a verbal response?
- Instruction
- Primary Auditory Cortex
- Wernicke’s area
- Arcuate Fasciculus
- Broca’s area
- Primary motor cortex
What happens when an instruction is received through the ear, the tones are broken down and we need a written response?
- Instruction
- Primary auditory cortex
- Wernicke’s Area
- Arcuate Fasciculus
- Exner’s Area
- Primary motor cortex
