Crafting a Solid Thesis Statement You have one chance to make a good first impression. Usually, an AP World History reader can tell within the first few sentences whether or not an essay is going to be strong. A few essays can recover after a poor start, but first impressions matter. Consequently, nothing is more important in the first paragraph than the clear statement of an analytical thesis.
Dendrite Describe the path of an electrical impulse as it moves through a neuron. You must use the words axon, axon terminal, dendrites, myelin sheath, nodes of Ranvier, synapse and neurotransmitters in your description.
Inputs come from other neurons via chemical messengers neurotransmitters across a synapse to the dendritic tree or cell body of the neuron. If the neuron is depolarized to threshold, an action potential is fired in the axon hillock.
This action potential continues along the length of the neuron. Moves from one node of Ranvier to the next, in a process called saltatory conduction.
This occurs because the depolarization opens voltage-gated sodium channels. Sodium moves into the neuron and it moves up and down the length of the axon. The depolarization caused by the internal sodium at the next node in turn opens its voltage gated sodium channels, and the process continues along the length of the axon.
Ultimately, it arrives in the axon terminal or boutonwhere it again causes depolarization. This opens voltage gated calcium channels in the terminal, and calcium moves in, and binds to vesicles. This promotes the binding of the vesicles to the terminal cell membrane, and exocytosis occurs, releasing the contents of the vesicles the neurontransmitter to the synapse.
It diffuses across the synapse to a target cell, and binds to receptors there, and has an effect on the cell membrane potential of that cell. Describe one way in which neurons are similar to other cells in the body and one way in which they are different.
Like the other cells nureons inclyde a cell membrane and a nucleus. They carry out regular cellular processes. They have spcial parts: Nuerons also communicate through electrochemical processes. In this activity, you read that there are billions of neurons in the human body that vary in size and somewhat in structure.
Suggest and then support a reason why the body needs so many neurons. From birth to dearh the brain generates a considerable amount of information on a day to day basis.
How does the structure of each type of neuron relate to its function in the nervous system? Neuron has dendrites which receive the stimuli, and axons conduct the impulse. For this the shape of neuron is admirably suited.
Reread the first paragraph of the Introduction. Describe the types of stimuli your body is reacting to as well as the decisions you have to make.

Writing a thesis for an AP World History essay is a little different from other theses you may have learned to write in English or Oral Communications. Luckily, there is a basic format you can use for each of the three essays. AP’s high school World History course is a rigorous, college-level class that provides an opportunity to gain the skills and experience colleges recognize.
