Document Summary

Peripheral nervous system: ganglia (cell bodies): aggregations of cell bodies, nerves (axons): bundles of axons. Sources of nerves: spinal nerves, neck down; mostly spinal, cranial nerves: head; emerge directly from the brain, 12 nerves, most important nerve that we will talk about: optic & vestibulocochlear. Sight & organ of hearing: neck up; cranial. Parasympathetic: tends to conserve energy, promote digestion, secretion (i. e. , saliva or stomach acids), and excretion, reduce heart rate and rate of breathing: organization of the brain: based on embryonic development, slows down the heart rate. Mammals have larges forebrains: primates; human specializations. As do dolphins and whales (because they are mammals: midbrain, hindbrain, organization of the brain, forebrain. Also knowing as mesencephalon; middle brain: hindbrain. Hindbrain: myelencephalon, made up of the medulla; adjacent to the spinal cord, medulla (medulla oblongata) life support, especially breathing. Damage to the medulla can be life threatening.
