Neuroscience: is the scientific study of the nervous system. Neurons: nerve cells that are the basic building block of the nervous system. Fun fact: the brain is only 2% of body weight, but 20% of oxygen goes there! Extension of the nervous system: the nervous system extends around the body. eg. autonomic nervous system: sympathetic (fight or flight response): Increase heart rate and strengthens it (heart) Bronchi dilation, opening a bigger space (bronchi, lungs) Decreased digestive activity (digestive system, stomach, intestines) Glycogen is being broken down, and glucose is released to the bloodstream. (liver) Constricts vessels, increase blood pressure (blood vessels) Release of epinephrine (adrenal gland: parasympathetic: Increased digestive activity, stimulates activity (digestive system, stomach, intestines) Glucose being put back into glycogen=stored energy, don"t need to release glucose for energy. (liver) Dilates vessels, blood is back to its normal pressure (blood vessels) No release of epinephrine (fight or flight response) Neurons: in brief, they help transmit information across the body.
