Randy has been experiencing several disturbing symptoms over the last year including: muscle weakness, slow reaction time, visual perception issues, seizures, hearing loss, weight gain, a general sense of pain, and delusions.A.Explain why his doctors might be concerned with the following when making their diagnosis: oNeurotransmitters oHormones oMyelin sheath oOccipital lobe oTemporal lobe B.Describe how each of the following brain scanning techniques would aid the doctors in making their diagnosis of these symptoms: oPet scan ofMRI oEEG The symptoms could be due to damage to or malfunctioning of a certain part of the brain. Neurotransmitters either enhance or inhibit action potentials, and can be affected by many substances such as drugs. They can alter the performance of neurotransmitters in many ways. Randy’s slow reaction time may come from this issue. Myelin Sheath surrounds the axon of nerve cells, acting as an insulation layer and supportive structure. It speeds up neural messages traveling down the axon. It is essential for the proper functioning of the nervous system. Randy’s slow reaction time could come from an issue with his Myelin Sheath as the neurotransmitters wouldn't function as efficiently so both the central nervous system and the peripheral nervous system wouldn’tfunction as efficiently, meaning delayed reaction time both intellectually and physically throughout the body. Randy having damaged myelin sheath could explain his muscle weakness as well. The myelin sheath being destroyed would lead to loss of neural functioning in those cells and decreased communication from the brain meaning the muscles can’t heal
