Two Nervous Systems • Central Nervous System (CNS) • Brain & Spinal Cord • Peripheral Nervous System (PNS) • Cranial Nerves, Spinal Nerves, Autonomic Nervous System Biological Psychology Ch 2
Orienting Around Your Body • 3 Slices • Sagittal (Divides into left and right) • Coronal, aka Frontal or Transverse Plane (Divides into front and back) • Horizontal (Divides into upper and lower) • Medial = towards middle • Lateral = towards side • Proximal = towards center • Distal = towards periphery Biological Psychology Ch 2
Orienting Around Your Brain • Anterior aka Cephalic or Rostral = towards head (or nose for brain) • Posterior aka Caudal = towards tail (or back for brain) • Grey Matter = Cell Bodies • White Matter = Axons Corpus callosum Biological Psychology Ch 2
