Chronic Pain

It is like a transmitter in the brain and is important for the signals that it sends to the central nervous system and according to the article I found on Functions of Dopamine, “it is what allows information to be passed from one neuron to another”. (Functions of Dopamine, 2018) Some of the functions of dopamine are; motor activity, cognition, emotion, and reward. There are also disorders that are associated with having a low amount of dopamine such as depression and movement disorders. Some of the more serious disorders are schizophreniz, ADHD, OCD, Tourette’s syndrome, and drug abuse. Then if there is a death of dopamine neurons it causes Parkinson’s disease, where a person is robbed of the ability to have smooth and controlled movements.

This network like structure create a bulge called the pons. The pons is one major division of the metencephalon, while the other is cerebellum. The cerebellum is the large, convoluted structure on the brain stem’s dorsal surface. Cerebellar damage eliminates the ability to precisely control one’s movements and to adapt them to changing conditions. The other part is Mesencephalon, which also has two divisions like the metencephalon.

It is responsible for the secretion of hormones and processing of emotional responses. In addition, it deals with storage of memories, that is, determining which memories are stored and where those memories are stored.Other functions include autonomic responses as a result of fear and in initiating arousal. It forms part of the limbic system. Olfactory Bulb It forms the end part of the olfactory cortex and is an extension of the ventral surface of the brain (Freberg, 2009). It is responsible for receiving and processing information concerning smell.

It consists of the sympathetic nervous system and the parasympathetic nervous system. The primary function of the sympathetic system is to stimulate your fight-or-flight response, while the parasympathetic system enables you to maintain normal functions such as digesting and keeping the body at rest. Part 2: The Structure of the Sympathetic Nervous System Transmission of signals in the sympathetic nervous system is accomplished through a network of nerve cells called neurons. There are two types of neurons – the preganglionic neurons have short fibers that originate from the spinal cord’s thoracolumbar segments, which communicate with ganglia adjacent to the spinal column, and synapse with the longer postganglionic neurons. Preganglionic neurons synapse with ganglia and release a chemical (neurotransmitter) called acetylcholine, which activates receptors on the postganglionic neurons.

Researchers also noted that abnormal development at a molecular level specifically impacted the cells involved in the production and maintenance of myelin, which are called oligodendrocytes . Connectivity of key brain areas impacted Their studies also discovered that some of the largest axons affected were unusually thickened. They say that these peculiar alterations may all act together to negatively impact the connectivity between the anterior cingulate cortex , which is a region of the brain implicated in processing emotions and cognitive functioning, and associated areas of the

The posterior approach is an indirect decompression and depends on the spinal cord which is able to shift posteriorly in an increased canal. That is why, kyphotic patient are not good candidates for a posterior approach and anterior impingement on the cord will remain. Instability and subluxation may also worsen with a posterior approach if fusion is not carried

The cortex which is a thin wrinkly layer squished inside the human skull is known for problem solving. How the cerebellum controls movement in an individual by telling the muscles what to do at every step. We also see how how the brain communicates by sending electric signals all around the body. Various diseases caused by brain damage is also covered and how this affects our memories; long term and short

The nervous system is responsible for controlling how your body acts and what it does, such as talking, walking, breathing, learning, and swallow. It also controls how your body reacts when there is an emergency. As I mentioned earlier the nervous system is a very complicated subject to talk about as it is comprised of different levels of organization.

The yips is a type of dystonia. According to Joseph Jankovic (2009: v) dystonia is a neurologic disorder characterized by involuntary, sustained, patterned, and often repetitive muscle contractions of opposing muscles that cause twisting movements, abnormal postures, or both. This essay is going to describe who Ben Hogan was and what lead to his downfall. The neuroanatomical and physiological functions of the three motor neural pathways (pyramidal system, extra-pyramidal system, cerebellar system) will be discussed as well as their role in movement control. Certain practical implications of learning new and re-learning neural pathways will also be identified within the text.

Spasticity: a multidisciplinary disorder If you or a loved one has been diagnosed with spasticity, it is important to gain a comprehensive understanding of the disorder and its impacts. Knowing the causes and effects of spasticity can give insight into treatment options and will improve your ability to manage the effects of the condition. What is spasticity and how is it caused? Spasticity is a condition that can be caused by damage to the area of the brain or spinal cord in which voluntary movement controls are located. It can also be caused by a number of velocity-dependent conditions affecting the Central Nervous System.
