How many cranial nerves are there?
12
What is the mnemonic for remembering the cranial nerves?
What are the cranial nerves?
Where do the olfactory fascicles penetrate (what is the name and which bone is it?)
cribiform plate of ethmoid bone.
What is in red and what does it do?
What is being pointed out and what do they do?
What is in red?
What structure is it deep to?
What area of the brainstem is it?
Substantia nigra.
Cerebral peduncles.
Midbrain.
What is the function of the substantia nigra?
What is this structure and what does it do?
What are the cranial nerves associated with the midbrain?
Which cranial nerves are associated with the pons?
Which ventricle is in the brainstem and where does it sit?
The 4th ventricle is in the pons.
Cranial nerves associated with the medulla?
What are the main roles of the medulla?
What connects the cerebellum to the brainstem?
The cerebellar pedunles
What are the functions of the cerebellum?
What is the name of the white matter of the cerebellum?
Which contains the choroid plexus?
The inferior
What is the green arrow pointing to.
What is the red box indicating?
What is this area important for?
What are these areas important for?
What are these bits of the cerebellum?
What are they called collectively?
What are they involved in?
What are each of these areas and what are they involved with?
Which peduncles are involved in these?
What are each of these structures and where is the primary motor cortex?
What are the arrows pointing to and what does this area do?
What is the prefrontal cortex involved with?
What are each of these areas?
What are they involved with?
What are these areas and what are they involved with?
Explain the somatosensory and motor homunculus areas?
What is more medial and what is more lateral?
Somatotopy: different parts of brain controling or receiving from different parts of the body.
Precentral gyrus: face more lateral and legs more medial side of the brain.
Region proportional to the amount of motor control. We use our mouths, hands and fingers a lot therefore the face and the hands control a large area of this.
Medial to lateral –> Feet to face.
Explain the corticospinal tract (origin to endpoint, where it crosses over and which structures in the brainstem it will go through).
This process is highly conscious, you choose to make these movements occur.
What do the basal nuclei do with regard to motor function?
Explain the discriminative pathway and which direction it takes.
WHERE DOES IT DECUSSATE?
Explain the pathway of the non-discriminative pathway?
Where does it decussate?
Spinocerebellar tract function?
What is the function?
What would an occlusion of the ACA, MCA and PCA do?
What are each of these areas and why are they important?
What is it called when you struggle to speak?
Aphasia
What part of the brain is associated with spacial representation?
What are each of these structures and what do these do?
If each of these areas were cut what would the visual field look like for that person?
