The Hypothalamus: The hypothalmus appears
to be even smaller that the the cerebellum, but if we did not have it our body would not be able to maintain homeostasis.
The hypothalamus is what controls our body temperatures.It controls balance, movement, and coordination.
It sends It controls balance, movement, and coordination messages to your body to react in a way that
will help maintain a suitable temperature, which for your body is 37 degrees celcius. When the brain detects that your body
temperature is rising, a message is sent to the hypothalamus, that then signals the sweat galnds to begin sweating. The
sweating can be a little gross, and an inconvience, it is what causes the
skin to cool off, after evaporation of the sweat has occured. When the body is cold the hypothalumus sends a signal to tha
oragns and tissues to increase body temperature. This is done by the arterioles to constrict, which limits blood flow. Then
the goosebumps occur becasue it is a way to reduce heat loss.
Brain Steam: The brain steam lies under the
cerbrum and in fornt of the cerebellum. This part of the brain is responsible for all the involuntary actions we do. Such
as breathing, and blinking. It is also in charge of all the functions your body needs to stay alive, digesting food,
and circulating your blood. The steam connects the rest of the brain to the spinal cord, which runs down your neck
and back, connecting your brain to the rest of your body.
