This storyboard does not have a description.
Sally had to walk to the store to buy some groceries.
When she walked outside, her nerve receptors in her skin realized that it was very cold.
These receptors then sent this information along the afferent pathway to the brain.
The brain received this info, and sent it down the efferent pathway, to the effector, the muscles.
The muscles decided that to warm up the body, they should spasm, so Sally began to shiver.
Sally decided to run, & after she started running, she re-gained heat.
As she began to get hot, her skin receptors felt this, and once again sent info to the brain.
The brain passed it along to the effector, her sweat glands, who made Sally sweat to cool her.
Finally she got to the store, and her body continued to sweat in efforts to cool off.
Once inside, she stopped sweating and reached homeostasis.
