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
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

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
