|
What is the nervous system? |
Vast, complex communication system |
|
|
What are the two main sections? |
The central nervous system and the peripheral nervous system |
|
|
What is the central nervous system made up of? |
Brain and spinal cord |
|
|
What is the peripheral nervous system made up of |
All other nerves |
|
|
What do the two main sections (peripheral and peripheral nervous systems) form |
Nerve cells called neurons |
|
|
What are the divided parts of the brain called? |
Hindbrain, forebrain and midbrain |
|
|
Where is the hind brain located? |
Near th back of the skull |
|
|
What does the hindbrain control? With examples |
Vital activities over which we have no conscious control, such as breathing, and voluntary muscle movement and reflect actions |
|
|
What is the hindbrain made up of? |
Cerebellum and medulla |
|
|
What does the cerebellum do? |
Recieves information from the sensory systems, and other parts of the brain |
|
|
What does the cerebellum us information for? |
To regulate posture and balance and coordinate fine muscles movements |
|
|
Cerebellum isn't affected by alcohol. True or false |
False |
|
|
What happens if cerebellum is damaged? |
It affects your muscle movement so you may as well walk like your drunk |
|
|
Where is the medulla located? |
The base of the hindbrain in front cerebellum |
|
|
What the medulla control? Use example/s |
Vital functions, like heart rate and breathing |
|
|
What would happen if you damage the medulla? |
Likely to lead to being placed on life support to regulate heart rate and breathing. But if too severe, pronounced 'brain dead' and may die if taken off life support |
|
|
What is there midbrain located? |
On top of the hindbrain under the cerebral hemispheres |
|
|
What does the midbrain do? |
Recieves messages from all yeh senses except smell and sends to them on to higher brain regions that deal with hearing, seeing, tasting and touching |
|
|
What is inside the midbrain |
Reticular formation |
|
|
What is the reticular formations main function? |
To screen incoming information so that higher brain centres can attend to important information and not be overloaded with less important information |
|
|
What does the reticular formation play a role in? |
Controlling sleeping and walking and our level of alertness |
|
|
What out of the midbrain, hindbrain and forebrain is the most developed and largest? |
Forebrain |
|
|
What does the forebrain play a major role in? |
How we think, feel and behave |
|
|
What does the forebrain consist of? |
Hypothalamus, thalamus and cerebral cortex |
|
|
What is the thalamus? |
Two oval parts that filter information from all senses except smell and passes it on to the appropriate part of the brain for processing |
|
|
What happens if you damage the thalamus? |
Reduced sense of touch or visual or hearing impairment |
|
|
Where is the hypothalamus located? |
Just below the thalamus |
|
|
Where is the thalamus located? |
In line with our ears |
|
|
What does the hypothalamus do? |
Release of hormones controlling body temperature, our biological clock, sex drive, and thirst and hunger needs |
|
|
Where is the cerebrum located? |
Lies above and in front of the cerebellum |
