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.

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

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

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

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
