Unit 5 Lesson 10: BioFlexBook Questions
(1) What is Action Potential and how is it generated?
Action potential is when the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials are generated by special types of voltage-gated ion channels that are in a cell's plasma membrane.
(2) Explain how messages are sent from one neuron to another (included in your answer is a detailed description of the anatomy of a neuron).
Neural messages are sent from one neuron to another by chemicals known as neurotransmitters.
(3) What is a synapse and how is information transmitted at the synapse?
A synapse is a place where an axon terminal meets another cell. When an action potential gets to the axon terminal, the axon terminal releases molecules of a chemical called a neurotransmitter.
(4) Using any number of drawing functions/aps and your iPad, sketch two connected neurons; also, sketch a neuron to muscular tissue connection. In a short paragraph, explain the differences in these two connections (if there is one; if not, explain in what ways they are similar).

(5) Name and describe the 4 principal parts of the brain.
The 4 principal parts of the brain are frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The frontal lobe has to do with reasoning, the parietal lobe has to do with touch or feeling, the temporal lobe has to do with hearing, and the occipital lobe has to do with sight.
