WE LEARNED A LOT OF THINGS THIS WEEK ESPECIALLY ABOUT THE BASIC INFORMATION ABOUT OUR BRAIN AND SPINAL CORD. THAT THEY ARE THE MAIN DIVISIONS OF OUR NERVOUS SYSTEM. OUR NERVOUS SYSTEM IS DIVIDED INTO 2 PARTS THE CNS (CENTRAL NERVOUS SYSTEM) AND PNS (PERIPHERAL NERVOUS SYSTEM). OUR CNS IS COMPOSED OF THE BRAIN AND THE THE BRAIN STEM WHILE OUR PNS IS COMPOSED OF THE SPINAL CORD AND THE SPINAL NERVES. WHICH IS MAINLY TACKLED IN THIS WEEK. FOR EXAMPLE THE SO CALLED DEEP GROOVE IS THE VENTRAL MEDIAN FISSURE AND THE SHALLOW GROOVE IS THE DORSAL MEDIAN SULCUS. THE AREA WHERE THE NERVES HAS THEIR CELL BODIES IS THE GRAY MATTER HORNS.
