1. Somatic nervous system
1.1. consits of
1.1.1. Sensory neurones
1.1.1.1. Relates to sensation orc physical senses
1.1.1.1.1. Hear
1.1.1.1.2. taste
1.1.1.1.3. touch
1.1.1.1.4. see
1.1.1.1.5. smell
1.1.1.2. transmit information from the senses to the brain
1.1.1.3. Anything that stimulates the senses will be relayes to the brain
1.1.1.3.1. brain processes the info and responds to it
1.1.2. motor neurones
1.1.2.1. Relating to motion or physical activity
1.1.2.2. transmits information to the muscles from the brain
1.1.2.2.1. resulting in movement
1.2. Sensory and motor pathways have to work together
1.2.1. voluntarily
1.2.2. involuntarily
1.2.2.1. reflex
1.3. Examples
1.3.1. Picking up a pen
1.3.1.1. voluntary
1.3.2. touching something hot
1.3.2.1. involuntary
2. Autonmic system
2.1. involutary or unconscious actions
2.2. happens without you thinking about it
2.2.1. automatic
2.3. controls and regulates
2.3.1. heart rate
2.3.2. Gut movement
2.3.2.1. Peristalsis
3. The central nervous system
3.1. Body's control centre
3.2. what is consists of
3.2.1. Brain
3.2.2. Spinal cord
3.2.2.1. connects the brain to every area of the body
4. Spinal cord
4.1. A bundle of nerve fibres and tissue
4.1.1. connects nearly all parts of the body to the brain
4.2. Is protected by specialised bones called vertebrae
4.2.1. They have a hollow centre that the fibres can run through
4.3. Transmits info to and from the brain
4.3.1. through nerves
5. Nervous system
5.1. Recieves
5.2. transmits
5.2.1. to information from the external and internal environment
5.2.1.1. through a collection of nerve cells
5.2.1.1.1. carry message from one part of the body to another
5.3. and responds
6. Peripheral nervous system
6.1. any other nerve outside of the CNS
6.2. Relays information from the brain and spinal cord to the rest of the body and vice versa
6.3. Includes:
6.3.1. Autonomic
6.3.2. Somotic system
6.3.2.1. sensory nerves
6.3.2.2. motor nerves
