During today's Anatomy and Physiology class, we started working on the respiratory system. We learned that the respiratory system provides oxygen to the body’s cells while removing carbon dioxide and that there are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.
What occurs when the nerve impulse reaches the terminal of the neuron? How is the signal continued. These are the questions to be discussed today. Define and discuss pre synaptic and post synaptic neurons, neurotransmitters, where and why they are produced. The effect on the post synaptic neuron of the chemical neurotransmitters to cause the next neuron to fire. Differentiate between excitatory and inhibitory impulses, inactivators and uptake inhibitors.
Today, we have finished with the Chapter "The Nervous System" by watching two videos where we could see in an audio-visual way how the eyes process the information and this is sent to the brain and how millions of nerve receptors are in our skin colecting information and sending it to the brain.
Briefly review anatomy and physiology of nerves and neurons. Introduce the synapse and use an image to display it. Discuss the nerve impulse as an electric potential traveling along the axon.
Show a polarized neuron, explain how it becomes depolarized and then re-polarized. Define threshold stimulus, firing of a neuron, and effector organs.

Lesson Comments
We had some computer difficulties on Nina's end, but eventually worked through it. This was an on line lesson.
During today's Anatomy and Physiology class, we completed the review of the chapter. Lenas has learned the different parts and functions of the nervous system. She has shown her knowledge and is ready to move to the next chapter.
During today’s Anatomy and Physiology class, we continued working on the divisions of the nervous system. We defined that the autonomic nervous system is divided into the sympathetic and the parasympathetic systems. After that, we defined the synapses as the junction between a neuron and another cell, and finally, we defined the difference between chemical and electrical synapses.
