Chapter 3 Notes: central nervous system - Neuron= sensory (afferent) bring impulses into body, motor (efferent) release impulses from body, interneuron are connecting neurons on spinal cord - Negative charge - Rest when not in use - Nervous system A. Peripheral Nervous system 1. Somatic- division (voluntary) 2. Autonomic- division (involuntary) a. Sympathetic- emergency/fight or flight b. Parasympathetic- calms system/establish homeostasis B. Central Nervous system 1. Brain- split brain theory= divided into 2 sections that look same but function differently a. Left- logic, language, reasoning, linear, sequential, math, details b. Right- emotions, holistic, visual, special integration, artistic, interpret, geometry 2. Spinal Cord - Dendrite- pathway where chemical info enters neuron
