If we look at the base of a brainwhich has just been removed from a skull,
:05:01
there's very little of the midbrainthat we can actually see.
:05:05
Yet, as I demonstratedin my lecture last week,
:05:08
if the under aspects of the temporal lobesare gently pulled apart,
:05:15
the upper portion of the stemof the brain can be seen.

This so-called brainstemconsists of the midbrain,
:05:26
a rounded protrusion called the pons,
:05:31
and a stalk tapering downwardscalled the medulla oblongata
:05:35
which passes out of the skullthrough the foramen magnum
:05:38
and becomes, of course, the spinal cord.

Are there any questions before we proceed?
:05:45
