If we look at the base of a brain
-
which has just been removed from a skull,
|
2 |
00:05:1.560 |
00:05:5.520 |
|
-
there's very little of the midbrain
-
that we can actually see.
|

00:05:5.600 |
00:05:8.760 |

Yet, as I demonstrated
-
in my lecture last week,
|
4 |
00:05:8.840 |
00:05:14.720 |
|
-
if the under aspects of the temporal lobes
-
are gently pulled apart,
|
5 |
00:05:15.600 |
00:05:19.400 |
|
-
the upper portion of the stem
-
of the brain can be seen.

This so-called brainstem
-
consists of the midbrain,
|
7 |
00:05:26.080 |
00:05:29.960 |
|
-
a rounded protrusion called the pons,
|
8 |
00:05:31.000 |
00:05:35.000 |
|
-
and a stalk tapering downwards
-
called the medulla oblongata
|
9 |
00:05:35.080 |
00:05:38.720 |
|
-
which passes out of the skull
-
through the foramen magnum
|
10 |
00:05:38.800 |
00:05:41.800 |
|
-
and becomes, of course, the spinal cord.
|
11 |
00:05:42.480 |

Are there any questions before we proceed?
|

00:05:45.160 |

I have one question, Dr Frankenstein.

That's Fronkonsteen.

I beg your pardon?
