S3 L2 Introduction to Neuroanatomy: general organisation and functional anatomy Flashcards
Nervous system has two areas:
- State name of both
- Describe what’s anatomically included in both
- What do sensory and motor neurones look like?
pic
What is the forebrain?
- 2 major parts - what do these major parts include?
What is the brainstem - what does this include?
What is the cerebellum?
pic
Forebrain:
- Cerebral hemispheres and cortex
- What is the cortex?
- What is grey matter?
- What are the dips and ridges called?
- What is white matter?
- What are fissures?
pic
How is the hemispheres seperated into lobes?
Describe the specific names of the seperatiosn and the lobes?
pic
Label the following diagram of the left hemisphere
pic
Label diagram
- What is the ventricle ‘covered’ by?
Septum pellucidum
Terminology for different orientation of brain anatomy
pic
Rostral - ‘nostril’
Brainstem - structures included in this?
Major functions of brainstem?
What information has to travel through the brainstem?
pic
Lobes of the cerebral hemisphere
- 4 lobes name and describe role
- 2 specific gyrus need to learn about…
pic
What is the uncus?
What is an uncal herniation?
What will this affect?
pic
Recap of:
- Primary Motor Cortex
- Primary Somatosensory Cortex
pic
Topographical Representation of the body
- What is the layers of neurones and where they are ‘linked to’ in the cortex
- Model/pic to help remember this
- Lesion at a specific part of the cortex - what will this affect?
pic
Motor pathways: Cortex to peripheral nervous system
- Draw out pathway
- State the route…
- How about sensory pathways?
pic
Recap of spinal nerves and there route
- main points
pic
Relationship between the primary motor cortex and cranial nerves
- draw out this route
- What is the difference between spinal nerves (route) and cranial nerves (route)
pic
Recap - Cranial Nerves connection to the primary motor cortex
pic
Where are the following:
- Corpus callosum
- Thalamus
- Hypothalamus
- Pituitary gland
- Midline vermis
- Lateral ventricles
- Cerebellum tonsils
- Peduncles
- Septum pellucidum
GW:
- Purpose of the connective tissue folds?
- What is conning?
- What does the different cranial floor fossa’s look like?
Stabilise the brain, acts as rigid divides (so rigid, can’t accomodation with increased in pressure)
Conning: Cerebella tomnsils, raised intracranial pressure, push the cerebella tonsils through the foreamen magnum
pic
GW:
- What do lateral ventricles look like on CT, why do they look like this?
GW:
- Label structures on this MRI
