Understanding the Nervous and Endocrine Systems: Neurons, Hormones, and Brain Functions

Explore the complexities of neurons, hormones, brain regions, and their functions in controlling behaviors like aggression, sleep, and depression. Discover how drugs like morphine and SSRIs affect brain communication and behavior. Learn about key brain structures like the medulla, pons, cerebellum, and cerebrum, as well as the role of hormones in regulating bodily functions. Delve into the fascinating world of brain lateralization and hormone examples.

  1. Bio 17 – Nervous & Endocrine Systems

  2. Atoms and Ions

  3. Plasma Membranes

  4. Transport

  5. Resting Potential

  6. Action Potential

  7. How Neurons Communicate… IPSP = Inhibitory Postsynaptic Potential EPSP = Inhibitory Postsynaptic Potential

  8. Aggression; Serial killers low levels; important for sleep and low levels assoc with depression

  9. Drug Effects Morphine SSRI – Lexapro; Prozac

  10. Morphine = Opiate Receptor Decreased GABA Increase Dopamine

  11. Reflex

  12. The Brain

  13. The Brainstem * • The Medulla Oblongata and the Pons controls breathing, heart rate, digestion • The Cerebellum controls coordination of movement and balance (Karate; Dance. Separate Section of the brain)

  14. Stairs…

  15. The Midbrain * • The Midbrain receives, integrates, and projects sensory information to the forebrain

  16. Thalamus • conducts information to specific areas of cerebrum • _____________ • produces hormones and regulates body temperature, hunger, thirst, sexual response, circadian rhythms

  17. * • Cerebrum • with cortex and corpus callosum • higher thinking

  18. Cerebrum * • Lateralization • Right – Pattern Recognition, Face Recongition, Spatial Relations, Nonverbal thinking • Left – Language, Math, Logical Operations

  19. Cerebrum

  20. Cerebrum
