from The Neurophysiology Pre- Lab Analysis

This week's module involved anesthetizing a leech in low concentrated ethanol solution and dissecting it to view the ganglion hidden beneath the organism's gut. In the process, we made use of highly sensitive equipment and fluorescent dyes to manually view the cell under study. Precision and accuracy were needed in order to successfully complete the dissection and obtain the expected results.

The Neurophysiology laboratory exercise was an eye-opener in the sense that the nervous system's structure was greatly explored. Various aspects of stimuli and how leeches are designed to record sensory information through each segment of their segmented bodies was a topic of interest. The Use of laboratory equipment to research sensory impulse recording simplified the research and identification of various cell types from the atlas provided.

In this exercise, various terms were provided in the description of the different parts of the ganglion. Electrical signals (action potentials) exhibited in the ganglion were amplified and recorded in an oscilloscope that assisted in the identification of the type of cell being observed. Overall, it was the easy description of terms and facilitation of the electrical equipment that enabled me to completely understand the exercise.

The Cardiology laboratory exercise provides a virtual experience of patient heart disease/disorder diagnosis patterns that are currently in use in modern hospitals. The laboratory introduction included a study of different terminologies that are used to signify conditions or certain parts of the heart's anatomy. It was imperative that before taking the first patient in for diagnosis, one ought to understand the terminologies in use in order to correctly understand the patient's condition. Similarly, a glossary of terms was provided for reference in the event that one does not entirely understand the questions and terms introduced in the doctor's room/quiz.

My understanding of the laboratory exercise hinged on the ease of understanding the images provided for every patient. The understanding of the operations of the diagnostics tools provided was also a key necessity in order to know what angle or what activity was in the simulations provided.knowing what sort of image can be provided by each machine enabled one to clearly identify the specific parts of the heart including the valves and their exact locations in relation to the orientation of the images being simulated. The entire exercise was very exciting and informative. 

The functions of the heart and its operations were clearly outlined in the introduction to the lab, and the definitions and explanation of the patient's symptoms well described in the notebook following a detailed examination of the patient using the virtual machines/diagnostics tools in the laboratory. The three patients were correctly examined albeit with difficulty, sighting reasons such as the initial understanding capability of the simulations provided, and non-familiarity with the instruments used for assessment. Overall, the laboratory exercise was an amazing task and the successful completion of the lab a remarkable thing.
