Autonomic nervous system

The autonomic nervous system is apart of the nervous system that receives instructions from the brain. It has two parts which are the sympathetic and parasympathetic. The sympathetic nervous system controls the bodes response to a perceived threat and is responsible for the fight, flight or freeze response. Where as the parasympathetic nervous system function is to control the homeostasis and the bodies rest and digest response. The sympathetic nervous system has a thoraco-lumbar outflow from…

distal part long axons because of the increase in myelin. Moreover, degeneration of the distal part of long axon because inadequate axonal transport to distal ends of axons. The pathology of polyneuropathy will lead to several sensory, motor, and autonomic function changes. Primarily, demyelination and degeneration of axons, it will lead to changes in sensory function, resulting in decreased sensation or impaired vibration senses. In addition, changes to motor function resulting in muscle…

the difference between hot, cold, and dull and sharp, but cannot feel if something is burning them. People with this disorder also have very overt autonomic symptoms, so they tend to show a lot of their actions that are supposed to be involuntary. Congenital Insensitivity is a genetically transmitted disorder, also known as hereditary sensory and autonomic neuropathy type four. When both parents carry the gene mutation, there is a 25% chance the child will inherit the disorder during the…

Stressed lifestyle and personality are some of the psychological factors that influence health and behaviour in our lives. However, our response to stressors determines our ability to control and manage or develop illness out of the stress. “Stress is experienced when a person’s perceived environmental, social, and physical demands exceed their perceived ability to cope, particularly when these demands are seen as endangering the person’s well-being in some way” (Cardwell & Flanagan, 2012).…

The central nervous system is crucial to human function; it consists of the brain, spinal cord and a network of nerves moving to the rest of our body. It controls everything in the body e.g. emotions, senses, responses, reactions, body balance like temperature and heartbeat as well as movement of our muscles and glands. The CNS (Central nervous system) covers the brain and spinal cord where the PNS (Peripheral nervous system) is made up of the nerve fibre’s that branch off from the spinal cord…

A lot of what makes us up as people consists of neurons. Neurons are responsible for our bodies “communication system.” So much happens within our bodies at such a minuscule amount of time, and learning about the process made me realize how much needs to happen for me to feel a certain way or perform a certain action. In a neuron, it first has to have a certain amount of depolarizing ions for there to be an action potential. When that action potential is reached, charge can be sent through the…

of the organism’s nervous system, which results in death. 1 “Malathion was first registered for use in the United States in 1956 by the United States Department of Agriculture (USDA), and it is now regulated by the United States Environmental Protection Agency (U.S. EPA)”.…

eating foods rich in glutamic acid and glutamate. You can also stimulate your body to produce serotonin by eating foods rich in tryptophan. GABA and Serotonin act as gatekeepers in the body. GABA is the chief inhibitory neurotransmitter of the nervous system. GABA is also involved in the production of endorphins, brain chemicals involved in the feeling of happiness. (Onedietandhealth.com) GABA and Serotonin are counterparts to Dopamine and Acetylcholine that allow us to move, act, focus and…

Therefore, the brain matters, it plays a role in behaviors and need to know the level of analysis. The types of of disorders are neurology, psychological disorder and neuropsychological disorder. Neurology is a disorder involving diseases that connect with brain, spine and nerves which body nervous system. The examples are many diseases; one of…
