In the recent weeks we have been getting a very good understand of the brain based on the important neurotransmitters that are needed that allows people to navigate and do the necessary motor functions to get things done in their personal lives. The class was taught on the different neurotransmitters that exist and their different stages. Dr. Gates taught about the importance of the neurotransmitters since they allowed for the communication of neurons within the brain which allowed for the individual to react in the necessary possible. We got an understanding how these NT (neurotransmitters) originated from the neuron and released into the synaptic cleft. We were able to learn and get an understanding of the synaptic clefts and the release of the neurotransmitters within the cleft and how they can also be blocked. The different NT can either be excitatory or inhibitory and that is based on the NT and the receptor that it actually needs to bind with on the post synaptic cleft. The different categories of NT’s that we studied were small molecule transmitters, peptides and gaseous NT. The neurotransmitters section was not the easiest section to actually understand but our professor did her best to get it through to us and we tried our best to grasp the information and to focus on all the important, high-yield material that she thought we would need. The class got an understood on what type of neurotransmitters that would be found in the blood or in the urine if the NT’s did not actually bind to a certain receptor and was not taken up by the re-uptake method. Knowing the NT’s that are not binding gives the physician an idea of what might be going wrong with the patient’s neural health.

NeuroAnatomy

In the recent weeks we have also been looking at the spinal cord and all of the great connections that actually run through it, and this was another challenging topic but was also very interesting. The class was able to get an understanding of the different spinal tracts that are used for the proper motor and sensory function throughout the spinal cord and the information is relayed in order to get to and from the brain. We were able to cancel out myths about the length of the spinal cord in the human adult body. We went through all of the cross sections of the vertebrae and got an understanding of the tracts/nerves that ran through the vertebrae and saw the different parts of the body that’s innervated by them. We also saw how the homunculus could be spread out throughout the vertebrae, the way different sections applied to different parts of the body. The class was able to also review about the dermatomes to get a better understanding of the tension lines and where they were felt particularly in the body. In the spinal we looked at some of the tragic diseases of the spine that has affected the science world by storm and is the same disease prince of science Stephen Hawking has suffered from which is called ALS.
