  1. Chapter 6 Biological Context of Psychiatric Nursing Care

  2. Neuroscience Topics for Psychiatric Nurses • Structure and function of the brain • Neurotransmission • Neuroimaging techniques • Biological rhythms and sleep • Psychoneuroimmunology • Genetics of mental illness • Biological assessment of the patient • Biological components of mental illness

  4. Figure 6-4C Schematic representation of midsagittal section of the brain.

  5. Figure 6-5 Structure and function of the brain. (From Carson RC, Butcher JN, Mineka S: Abnormal psychology and modern life, ed 11, Boston, 2000, Allyn and Bacon.)

  7. Figure 6-7 Neurotransmission. Bottom: 1, Neurotransmitter is released from presynaptic cell into synapse. 2, Neurotransmitter, recognized by receptor cell, causes channel to open, and ions are exchanged. 3, Exchange of ions causes impulse, which causes reaction in receptor cell. 4, Neurotransmission has taken place, receptor channel closes, and neurotransmitter returns to presynaptic membrane (reuptake).

  8. Figure 6-10 From the sun to the brain.

  9. Figure 6-11 Normal sleep architecture.

  10. Biological Assessment of the Psychiatric Patient • Health care history—General health care; treatments; brain impairment; cancer; lung and cardiac problems; diabetes; endocrine disturbances; menstrual, sexual, and reproductive histories • Lifestyle—Diet, medications and other remedies, substance use, toxins, occupation, injuries, or abuse • Physical examination • Laboratory values • Presenting symptoms and coping responses
