Parkinson’s disease, sometimes abbreviated as “PD,” is a neurological degenerative disorder that of the central nervous system. It is a progressive disorder, which means that its symptoms worsen over time. The rate at which it progresses, however, varies from person to person. The disease itself is not fatal, but some of the more serious symptoms can cause complications that lead to death. It affects as many as one million people in the US. The average age of onset is around 60, but some people

In 1859, French physician Jean-Baptiste Octave Landry first documented Guillain- Barré syndrome (GBS) as “ascending paralysis.” Guillain- Barré Syndrome is an acute, acquired peripheral neuropathy with a course that is usually monophasic (Hardy, Blum, McCombe, & Reddel, 2011). It is typically triggered after an infection and rarely during vaccination. While there is currently no known cure, there are ways to decrease the severity of the illness. Without treatment, this disorder is fatal and immediately

common category reported in clinical settings. This type of pain occurs due to trauma, tissue damage or inflammation that stimulates sensory nerve endings called nociceptors. Intense peripheral nociceptive stimuli will increase excitability of the nervous spinal cord, leading to central sensitisation in the presence of subsequent pain stimuli, increased intensity and lower pain threshold. Macintyre and Schug (2007) also described two types of nociceptive pain: somatic and visceral pain. Somatic pain

which regulates our breathing, heart rate and blood pressure. The Pons is responsible for the sleep-wake cycles, and the Cerebellum in controls balance, reflexes and movement. The Thalamus is a major relay center for the brain and the Peripheral Nervous System. The Hypothalamus controls the emotion and motivation and stress reactions, these are the functions that we share with all other vertebrates. The Cerebral Cortex is sometimes referred to as the “New Brain”, this is the portion of the brain that

sheath is also located on the axons. Nodes of Ranvierdo not have myelin sheath. Finally, there is the presynaptic terminal. This is where the axon releases the chemicals from one neuron to the next (Kalat, , Chapter 2.1 The Cells of the Nervous System ). Cell Body: is also known as soma has the ribosomes, nucleus, and mitochondria within it. The cell body has synapses on the surface. Dendrites: Are fibers that are

A class of drugs that is known to activate the sensorimotor system is known to us today as psychomotor stimulants. Psychomotor stimulants are comprised of cocaine, amphetamines, as well as other drugs with similar chemical compositions. What we know today about psychomotor stimulants is that they tend to bring about increased feelings of alertness, arousal, and behavioral elation. It is apparent that this class of drugs brings about both physiological and behavioral effects. In particular

Monoamine Oxidase is an extremely important enzyme in the body and plays an important role in the metabolism of Serotonin and Dopamine. MAOs are found in the in the nerve terminals around the body and is also heavily concentrated in the central nervous system (CNS). MAOs helps metabolise dopamine by actively catalyses the reaction of the neurotransmitters. The catalyst is present in to forms MAO-A and MAO-B both have potential to be used in treatment of neurodegenerative disorders. Rasagiline is selective

does, however, have the potential to be a medicine. Marijuana is frequently beneficial to the treatment of AIDS, cancer, glaucoma, multiple sclerosis, and chronic pain. Our bodies have two cannabinoid receptors (one in the brain and one in the immune system) which are responsible for the usage of THC within our bodies, meaning we were made to process it. There are two strains of ganja; Indica or Sativa. Although there are many types of weed, the effects don’t really vary that much. There’s the kind that
