2. 1st
SITUATION
• I’m thirsty so, I stand up of the chair in
my bedroom and I go to the kitchen.
There, I pick up a glass and I drink
some water. It’s nice!!
• This situation is an involuntary
action but it´s conscious.
3. EXPLANATION
• No enough water in the arteries (high mineral
salts)
• This is detected by receptors in arteries.
• It goes to the hypothalamus (electrical
impulses)
• Then, go to the brain cortex and it is a
conscious.
• The brain makes the muscles move , go to
the kitchen and drink water. ( Some process
are required)

SITUATION
• While I was practising hiking along some
meadows, I realised terrified that a huge
furious bull was running towards me. For
a while, the panic make me unable to
move, suddenly I became conscious and
began to run fastly away of the bull.
When I was safe, at the top of a tree, I
realised that I’m turned pale, cold and
breathing hardly. Moreover, my heart is
beating very fastly.
6. EXPLICATION
• Synapse links the end of a neuron and the
start of another
• This impulse goes to the spinal cord
• Brain (different parts with different aims)
7. EXPLICATION 2
• Increased of heartbeat and dilation of
blood vessels (more blood provided to
muscle’s cells)
• The impulse goes to the motor neurons
• Effectors make a response to the stimulus
(motion of muscles …)
