What is the term for ridges in the brain?!
Gyrus
What is the term for the valleys in the brain?!
Sulci
What are the areas of the hindbrain?
Reticular formation
Raphe nuclei

Locus coeruleus
Which is pointing towards the back?!
Rostral or caudal
Caudal
Where is the raphe nuclei located?!
Medulla and midbrain
Where is the area prostrema located?!
Pons/medulla
Where is the locus coeruleus located?!
Pons
What functions is the reticular formation involved in?!
Alertness and CV functions
What does the raphe nuclei contain?!
Serotonin cells
What does the area prostrema contain?!
Chemoreceptors trigger zone
What does the locus coeruleus contain?!
NA positive cells
What are the areas of the midbrain?!
Substantia nigra
Superior colliculus
Periaqueductal grey matter
Red nucleus
What is the parietal lobe involved in?!
Integration from different senses
What are the two sections of the forebrain?!
Telencephalon and diencephalon
What does the central sulcus separate?!
Primary motor cortex and the primary somatosensory cortex
What does the diencephalon contain?!
Hypothalamus
Thalamus
Limbic system
Pituitary gland
What is the temporal lobe involved in?!
Smell and sound
What are the three components of the meninges?!
Dura mater: thickest and external
Arachnoid mater: underneath the dura mater - does not go into the sulci
Pia mater: internal layer, goes into the sulci
What is the occipital lobe involved in?!
Sense of sight
How do the third and fourth ventricle connect?!
Via the cerebral duct
What is the frontal lobe involved in?!
Conscious thought
What does the telencephalon contain?!
Cerebral hemispheres, cerebral cortex and neocortex
Basal ganglia: extra pyramidal motor system
Corpus striatum, caudate nucleus: motor disorders
Which is on top?!
Dorsal or ventral
Dorsal
What do the different parts of the midbrain do?!
Substantia nigra: dopamine containing cells
Superior colliculus: visual inputs
Periaqueductal grey matter: emotive pain pathways
Red nucleus: motor control structure
Where is reticular formation located?!
Midbrain and medulla
