2. Gliobastomas
The gliobastoma is the most dangerous brain cancer, I was going through
the internet and I saw a notice briefly explaining it and that made me want
to know more about it and discover how is it related to neurobiology, in this
presentation, i'm going to explain gliobastomas and other types of brain
tumours with the resources and knowledges that this course has tought me.
3. It represents 15% of all brain tumours.
They can start from normal brain cells or from an existing low grade
astrocytoma.
There is no known method to prevent this cancer and usually is cured by
surgery and other not so common methods.
Despite maximum treatment, the cancer almost always recurs. Only 5-
10% of people surviving more than 5 years.
So you know and understand what a gliobastoma is, i'm going to explain a
little bit about it :
Introduction
4. Affected parts
It starts as a growth of cells in the brain or spinal cord, In the brain it occurs in
the cerebrum and the cerebral hemispheres especially in the frontal and
temporal lobes of the brain.
It occurs in the CNS- Central Nervous System and starts in some cells called
astrocytes which, provide support to the neurons and, if they have any
cancer, they can infect neurons, as in week 1 of the course itś explained that
tumours dont start directly in them.
5. Affected parts
In this images here we can see where
is the tumour located, in the cerebrum.

6. This types of cancers affect the cerebrum as the tumour grows. It pressures
with a lot of force and it changes the functions of other brain tissues.
That makes the person with the tumour could have different symptoms that
go from headaches to nausea and balance problems.

In these two photos we can
see the red circle surrounding
the gliobastoma and that it is
swollen as it has grown and
expanded.
In this one we
can also see it is
swollen and red.

8. Gliomas: They are developed from glial cells, that are explained in week 1
of the course.
Choroid Plexus: They begin in a type of cell that creates the surrounding
fluid of the brain and spinal cord.
Embryonal: They start in cells that are left from the fetal development.
Germ: They start in reproductive cells.
And there are lots of other tumours that humans can suffer from, but, this is
only a little summary for you to know others appart of the gliobastomas that
are also important.
Other Tumours
9. This course has taught me numerous things, from the simplest to the more
difficult and it has helped me to expand my knowledge about neurology,
they daily one and the one that is more specific.
It has helped me to develop my idea of this project thanks to its section
talking about brain tumours and also thanks to the resources that were
uploaded in order to know more about them. Appart of teaching me
about tumours, it also has helped me to know more about the human body
and in several sections it has showed practices with some nervous system
parts. In general, I liked a lot this course and I am really thankful of all that
it has taught me.
What this course taught me and how it has helped to
do this project:
10. Thank you so much for watching and I hope
you´ve learned about Gliobastomas!
