September 15 (A-Day) & 16 (B-Day) Objective: Explain how the brain and nervous system communicates specifically addressing neurons, neurotransmitters, and synapses. 1.CBM 2.Neuron construction 3.Parts/Types of Neurons 4.Synapse 5.Neurotransmitters 6.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 gapPost 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
