  1. Have you ever swerved to avoid hitting a deer?

  2. HOW DOES THE BODY COMMUNICATE INTERNALLY?

  3. Nervous System: Network of nerve cells carrying messages of electrical and chemical energy throughout the body.Endocrine System: Sends follow up messages that support and sustain the emergency response initiated by the nervous system.

  4. Your body doesn’t only communicate in a “panic”. These systems also react to things such as passing a difficult test, falling in love, winning a close sports game…

  5. The Nervous System and TheEndocrine Systemare the foundation for thoughts, emotions, behaviors.

  6. Nervous SystemEvery part of the nervous system made up of the same components. Nerve cells, or neurons.Neuron: cell specialized to receive, process, and transmit info.

  7. The Behaving BrainNo complete sentencesVideo goes quick – we WILL go over questions

  8. The Structure of a Neuron

  9. The Neuron • Types of Neurons • Sensory neurons (carry messages from sense receptors towards the Central Nervous System) - Motor neurons (carry messages from CNS toward muscles and glands) - Interneurons (carry messages between nerve cells)

  10. Sensory neurons: when you test water SN carry message to brainMotor neurons: deliver message from brain to move the shower knobs

  11. The Structure of a Neuron

  12. Dendrite: receiver part, accepts incoming messagesMyelin Sheath: allows impulses to transmit quicklyAxon: transmitter fiberTerminal Buttons: structure which passes messages across synaptic gapSynapse: Gap between nerve cellsCell Body: (soma) central part of neuron , assess messagesIon: charged chemicals which give energy to axon

  13. Dendrite Drug Ad

  14. Neurotransmitters* Terminal buttons  electrical impulse ruptures sacs of neurotransmitters* Lock and key fit  stimulates neuron to send message * Recycled * Imbalances can underlie disorders * Drugs used to help disorders mimic neurotransmitters (so do street drugs)

  15. * Molecules are broken down and return to terminal buttons* How do drugs affect this process?

  16. Neurotransmitter Worksheet

  17. Plasticity:* Neurons have the ability to change* Adapt/modify based on experience * Learning  new dendrites on neuron* Use it or lose it

  18. Stand upArms out

  19. Dollar bill exercise
