Presentation Transcript

  1. September 15 (A-Day) & 16 (B-Day) Objective: Explain how the brain and nervous system communicates specifically addressing neurons, neurotransmitters, and synapses. • CBM • Neuron construction • Parts/Types of Neurons • Synapse • Neurotransmitters • HW: Read pg 67-72, vocab; start AP bio assignment

  2. Task • Get into a group of 3-4 people. • Each group will be given the following items: • 3 Pipe cleaners • Yarn • A Pom • Saran Wrap • Using this items, construct a neuron, which includes the following parts: • Soma (Cell Body) • Axon • Dendrite • Myelin Sheath • Synaptic Terminal • After constructing the neuron, call me over and explain the parts. • Then, draw a picture of the neuron on a piece of paper. Use different colors to represent the different parts. Then, label what each part is and explain what it does.

  3. Nervous System Cells Neurons • Interneuron • Afferent Neurons • Efferent Neurons Glial Cells • Support neurons • Produce myelin sheath • Influence transmission of messages

  4. Communication between Neurons • Synaptic gap Post Synaptic Potential • Terminals - Inhibitory • Vesicles - Excitatory • Receptor sites • Action potential • Resting potential/Sodium Potassium Pump • Refractory period

  5. Cell Communication cont’d • Neurotransmitters • Types: • Acetylcholine • Dopamine • Serotonin • GABA • Glutamate • Opioid peptides • Endorphins • Neuropeptides • Substance P Agonists & Antagonists

  6. Homework • Read pg 67-72; work on vocab • Work on AP Biology Assignment • Work with another student to show 20 vocabulary words from Chapter 2 (pg 97). • This may be done in two ways: • Create drawings/illustrations that include the word and definition. Make them colorful and suitable for mounting. • And/Or: • Create a poem that rhymes and has a particular pattern. Type up the poem and make it suitable for framing. • You may do any combination of these two as long as there are 20 different vocabulary words once the assignment is completed. This assignment is worth 40 points. • Due date: A-Day – Wednesday September 29; B-Day Thursday September 30
