Abdul wakes up very sleepy in the morning but he must wake up and quickly get ready for his basketball game.
System and CNS
Abdul trips on the stairs and lands on his arm! As soon as Abdul hits his arm on the wooden flooring, this is where his Stimulus Response Pathway comes in to help.
System and Neurons
When Abdul hits his arm on the floor his effectors (muscles) will produce a response to detect the stimulus. The Stimulus/Stimuli is any change in the organisms environment, causing the organism to react. As for the response, it is an organism's reaction to a change in the environment, which would be Abdul getting up and crying.
Abdul can't go to his Basketball Match
It Really Hurts! Can I still go to Basketball?
No Honey, you must rest!
But before the response even happens, The stimulus is detected by the receptors. The receptors is a specialized group of cells that are able to transform the stimuli into electrical nerve impulses. These nerve impulses are then sent to the CNS (Central Nervous System) for further decision making. The CNS is your brain and spinal cord. It contains the brain which controls all your 5 senses.
The CNS also contains the motor, sensory, and relay neurons. The motor neurons will carry information within the CNS to the effectors for muscle movements. The sensory neurons will deliver all signals to the rest of the nervous system, and the relay neurons allows the motor and sensory neurons to communicate with each other.
It's amazing how all these neurons and functions are able to happen in just a quick second in the CNS. Abdul screams and quickly gets help from his mother. Abdul must recover and stay at home.
