Parkinson s Disease ( Cns ) And The Peripheral Nervous...

Parkinson’s disease â€Å"is described as a common disorder of the brain caused by a progressive deterioration of the areas that produce the neurotransmitter dopamine† (Fischer, 1999). It affects the nervous system, more specifically it affects the nerve cells in your brain that secrete dopamine. Dopamine is a chemical that is responsible for the movement and coordination of the musculoskeletal system. The nervous system is composed of two separate systems: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord while the PNS consists of the nerves that are outside of the brain and spinal cord. The brain receives information sent from the PNS via neurons. The CNS contains neurons which are the basic units of the nervous system. There are three different classifications of neurons: motor, sensory, and interneurons. The motor neurons transfer signals from the central nervous system to the muscles to help with movements. Sensory neurons transfer information to the central nervous system from external stimuli such as environmental factors. The interneurons transfer signals between the motor and sensory neurons. If a person is diagnosed with Parkinson’s the neurons that receive the information begin to fail and eventually die. A person that does not have sufficient amount of neurons is not able to receive dopamine a nd begin to lose coordination thus limiting their movement.

Microtubules average approximately 20 nm in diameter, and exclusively run longitudinally down neurites (meaning either an axon, or dendrite), with the purpose of both maintaining the cell s structure, as well as the control of its elongated projections (the length of axons, a nd dendrites). Microfilaments, measuring around 5 nm in diameter, are most abundant in neurites in random order, and orientation.

Currently, an effective strategy for regeneration of neurons that are lost in PD does not exist; however, nanotechnology has offered new avenues in the field of neural tissue regeneration. Nanostructured scaffolds have been shown to have the ability to promote neuronal growth and their excellent biomimeticRead MoreA Long Term Mental Disorder1344 Words   |  6 Pagesincluding amino acids, polyunsaturated fatty acids (PUFAs), myoinositol, and citrate, in the serum of schizophrenic patients.
