Picking up a box from the floor and placing it on a shelf Light entering the eye forms an upside-down image on the retina. The retina transforms the light into nerve signals for the brain. The brain then turns the image right-side up and tells us what we are seeing. Our brain then computes to pick up the box. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. the brain as a central computer that controls all bodily functions‚ then the nervous

all of the nerves that connect these organs with the rest of the body. Together‚ these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS. Efferent nerves in the PNS

About 40% of the body’s sodium is contained in bone‚ some is found within other organs and cells and the remaining 55% is in blood plasma and extracellular fluids. Sodium is important in proper nerve conduction‚ in aiding the passage of various nutrients into cells‚ and in the maintenance of blood pressure. Chloride ions also help to maintain proper blood volume‚ blood pressure‚ and pH of body fluids. Chloride is the major extracellular anion and contributes
