Surface FeaturesCurrent LectureFunctional Organization of the Nervous System- Central Nervous System- Peripheral NSDirection of Neural Flow- Sensory (incoming) pathways—bring info (NS afferent)- Motor (outgoing) pathways are efferent—leaves NSAnatomical Division of the NSNervous System:- Central NS- mediates behavioro Braino Spinal cord- Peripheral NS- transmits sensation, produces movemento Somatic NSo Automatic NS- Autonomic NS- balances internal functionso Sympathetic division (arousing)o Parasympathetic division (calming)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Finding Your Way through the Brain- Structures atop the brain or a structure within are dorsal.- Structures toward the midline are medial; sides are lateral.- Anterior is front; posterior is back.- Bottom is ventral.- Rostral (anterior), caudal (posterior).- Superior and inferior may be used to refer to structures located dorsally and ventrally.- Anterior → horizontal plane. Medial → sagittal. Dorsal → coronal.An Overview of Brain Function and StructureThe Brain’s Surface Features- Meninges: Three layers of protective tissue.- Dura mater: most superficial. Fibrous tissues.- Arachnoid layer: spiderlike appearance. Fluid inside cushions the brain.- Pia mater: softer connective tissue. Tightly covers brain.Surface FeaturesCerebral cortex- Frontal lobe.- Parietal lobe.- Temporal lobe.- Occipital lobe.Central sulcus- division between the
