PNS: Shwann cells CNS: oligodendrites Unipolar: impulses toward CNS Bipolar: eye, ear, olfactory Multipolar: away from CNS Afferent(sensory): to CNS (unipolar) Efferent (motor): away from CNS (multipolar) Association (internuerons) afferent and efferent communication in CNS (muilti polar) Axon Mylelin shealth ENDONEIRUIM surrounds each nerve fiber fasicle PERINUERIUM surrounds fasicle EPINEURIUM surrounds all fassicles grouped together Gyri: ridges Sulci: shallow grooves Fissure: deeper groves Central sulcus: divides frontal and parietal Lateral sulcus: divides temporal and parietal Pario occipital sulcus: occipital and parietal Longitudinal fissure: divides cerebral hemispheres Insula: fifth lobe of each hemisphere, covered by potions of temporal, pariental and frontal lobes Primary somasensory cortex: (located in postcentral gyrus of parietal lobe): where impulses from bodys sensory receptors located here, like pressure, pain etc

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
