2. occipital gyrus
3. pseudosylvian fissure
4. sylvian gyrus
5. ectosylvian gyrus
Name the cerebral landmarks
1. cruciate sulcus
2. precruciate gyrus
3. postcruciate gyrus
Name the cerebral lobe
Name the cerebral lobes
1. Frontal lobe
2. parietal lobe
3. occipital lobe
4. temporal lobe
What are the borders of the frontal lobe?
You're doing great guys!
cruciate sulcus, postcruciate gyrus and everything rostral
What are the borders of the temporal lobe?
sylvian gyrus and ectosylvian gyrus
What are the borders of the parietal lobe?
Rostral border is postcruciate g., caudal border is straight up (dorsal) from caudal end of pseudosylvian fissure
Name the primary cortical areas.
Which gyri and lobes are associated with the primary somesthetic area?
postcruciate gyrus (frontal lobe), rostral suprasylvian gyrus (frontal lobe), ectosylvian gyrus (temporal lobe)
Which gyri and lobes are associated with the primary motor area?
postcruciate gyrus (frontal lobe), rostral suprasyvlain gyrus (frontal lobe)
Which gyri and lobes are associated with the primary auditory area?
Ectosylvian gyrus (temporal lobe)
Which gyri and lobes are associated with the primary occipital area?
Occipital gyrus, occipital lobe
1. Which cortical lobe does not contain a primary cortical area?
2. What does this lobe contain?
1. Piriform lobe (I've also seen it spelled pyriform... not sure which is right)
2. Contains olfactory information
Label the parts
1. cruciate sulcus
2. ansate sulcus
3. primary somesthetic area I
4. primary visual area
5. suprasylvian sulcus (and primary auditory area - oops)
6. pseudosylvian fissure
7. primary somesthetic area II
8. primary motor area
Name the types of cells in gray matter.
Axons (the part very close to the cell body)
*cell bodies are the primary distinguishing factor between gray matter and white matter*
Name the types of cells/structures in white matter?
*note that there are NO neuronal cell bodies within white matter - main difference between white matter and gray matter*
What structure is the caudate nucleus associated with and what type of matter is it?
Caudate nucleus is part of the cerebral cortex, and is gray matter.
Unibrow of the lady
Connects functional areas of R and L hemispheres
Cheeks of the lady
Cerebral afferents and efferents
Carry information to and from cerebrum
One process at the cell body
Two processes at the cell body
Many processes at the cell body

4. Pia Mater
Which two layers of meninges make up the Leptomenengies?
Arachnoid + Pia Mater
Define Falx cerebri
Meninges that cover the external aspect of the brain
Define Tantorium cerebelli
Meninges in the space separating the cerebrum from the cerebellum
Dorsal Sagittal Sinus
Lies within the falx cerebri. It receives numerous arachnoid villi of the meninges and tributary veins from the cerebral hemispheres. Very important for the circulation of CSF from the
