What is the role of our brain?
Role of our brain
As a coordinator
* integrate and interpret information from different sensory cells
* produce senses and decides what to do
* send message to body parts to bring about response
Role of our brain
Explain the process of detect stimuli and make response
Role of our brain
- special sensory cells - detect stimuli and send message to brain
- brain - integrate and interpret information and send message to body
- body parts - bring out response
Role of our brain
