Nervous System and the Nervous System
While there was many different topics that I learned in this class I choice to do my paper on the Neurons of the Nervous System and the Nervous System. I choose this topic because I believe this is one of the most important systems in our body. As a kid I could remember older people telling me that I was getting on their nerves, and now that I’ve taken this class I somewhat understand how stress can work the nerves in your body and cause a person to have all kinds of medical problems.
A neuron is the functional unit of the nervous system, and a nerve is a bundle of neurons. The body has different types of neurons, it has myelinated neurons, which are neurons that have schwann cells and produce the myelin shealt which causes action potential to be faster an example of this would be like when you burn your hand, the fast response is a result of schwann cells. Non- Myelinated Neurons don’t have schwann cells which causes actions potential to be slower for example when you’re hungry you don’t have to eat right away is the result of no schwann cells.
Another major part of the nervous system is axons they carry impulses away from the body while dendrites carries impulses to the cell body. The nissle body synthesizes or breakdown proteins in the cells there are five components of reflex arch. The first on is the sensory receptor which detects a stimulus. The second on is the sensory neurons and its function is to relay info to the central nervous system (the brain and spinal cord). The third component of the reflex arch is the association or interneuron, which translates impulses. The motor neuron then carries the message to the effector muscle and the effector reacts or carries out the message that was received by the motor neuron.
The nervous system is broken into two parts, the Central Nervous System and the Peripheral Nervous System. The CNS is the part of the nervous system that integrates the information that it...
