Nervous System Flashcards
What is the purpose of the PNS?
parts of the nervous system
Complex: To send information from different areas of your body back to your brain, as well as carring out commands from your brain to other parts of your body.
Simple: Transmits information from the sensory organs to the brain
What does ‘PNS’ stand for?
parts of the nervous system
Periphal Nervous system
What is the purpose of the CNS?
parts of the nervous system
Recieves, processes and responds to information and stimuli
What does ‘CNS’ stand for?
parts of the nervous system
Central Nervous System
What neurons do the PNS use
parts of the nervous system
- sensory neurons
- motor neurons
The brain and spinal chord are part of what nervous sustem?
CNS, PNS ect.
parts of the Nervous system
The CNS
What four groups can the PNS be broken up into?
parts of the Nervous system
- The autonomic nervous system (ANS)
- The somatic NS
- The Sympathatic NS
- The Parasympathatic NS
What are the parts of the brain?
Parts of the Brain
- Cerebrum
- Cerebellum
- Brain stem
or - Frountal Lobe
- Pariental Lobe
- Occipital Lobe
- Tempral Lobe
Top on is on mind map and bottom one is in note book
what is the function of the Cerebrum?
Parts of the Brain
- intakes and co-ordinates movement
- regulates temperature
what is the function of the Cerebellum?
Parts of the brain
- Balance
- Co-ordination
what is the function of the Brain Stem?
Parts of the brain
- Involentary actions
Recal the 5 main sensory neurons
- eyes
- ears
- nose
- skin
- tongue
Recall the function of the sensory organs
- sight
- sound
- smell
- taste
- touch
Define the different receptors found in the body
- mechanoreceptors
- photoreceptors
- chemoreceptors
- thermoreceptors
- nociceptors (pain receptor)
Where can the different receptors be found in the body
e.g. photoreceptors in the eyes
- mechanoreceptors in ears and skin
- photoreceptors in eyes
- chemoreceptors in tongue and nose
- thermoreceptors in skin
- nociceptors (pain receptor) skin
