What is the nervous system made up of (2)
CNS and nerves
What is the CNS made up of (2)
Brain and Spinal cord
What are the 3 parts of the brain
- cerebrum
-cerebellum - medulla
What does the cerebrum look like in the brain
The biggest part of the brain
What does the medulla look like in the brain
The small long part of the brain next to spinal cord
What does the cerebellum look like in the brain
It looks like the cerebrum but smaller
What is the function of the cerebrum
Controls conscious thoughts, memory and personality
What is the function of the cerebellum
Controls muscle coordination and balance
What is the function of the medulla
Controls breathing and heart rate
What is the 1st step for the CNS to control the body
Receptors in the senses detect a stimulus
What is the 2nd step for the CNS to control the body
Electrical impulses carry the message along neurons
What is the 3rd step for the CNS to control the body
Sensory neuron takes message to the CNS
What is the 4th step for the CNS to control the body
Inter neuron operates within the CNS where the message is processed and a response is generated
What is the 5th step for the CNS to control the body
Motor neuron travels away form CNS and takes the response to an effector
What is the 6th step for the CNS to control the body
Responses may be a rapid action form a muscle to a slow response from a gland
