Somesthetic

Auditory

Motor 

Visual

Name the types of cells in gray matter.

Cell bodies

Dendrites

Axons (the part very close to the cell body)

Glia

Capillaries

*cell bodies are the primary distinguishing factor between gray matter and white matter*

20

Name the types of cells/structures in white matter?

Axons 

Glia

Capillaries

*note that there are NO neuronal cell bodies within white matter - main difference between white matter and gray matter*

21

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.

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
