Module 1 The Nervous System

Module Summary

Module Summary

In this module, you studied the nervous system and how it communicates to maintain homeostasis in the body. You investigated how various sense cells/organs help you to see a person, notice their smile, and hear their laughter from across the room. You explored how these sensations were transmitted electrochemically between neurons to specific areas of the brain so that they could be interpreted. Your discovered how your brain was able to send nerve impulses to your leg muscles so that you could walk in the direction of the person of interest. These communications were conscious. Other parts of the brain, such as the medulla oblongata, sent out unconscious messages via the sympathetic nervous system that altered your heart rate and caused your hands to become clammy. After that initial “hello”, your parasympathetic nervous system slowed the heart down and returned your body to homeostasis. You investigated how several disorders, such as multiple sclerosis, Alzheimer’s Disease, and Parkinson’s disorder disrupt communication in the nervous system, cause a loss of homeostasis, and require corrective technologies to attempt to bring the system back to homeostasis.

In this module you should have completed the following assignments Bio30 1.1.1 - Bio 1.1.8.

You should have also submitted tutorial summaries for tutorial videos 1.1.1 - 1.1.8 (Eight in total)

If the above is complete, you can now write the Nervous System Exam or the Nervous System Exam IPP .  Your key contact should send a password request.
