The Central Nervous System is composed of the brain and the spinal cord and one of it’s primary functions is to send out messsages to the rest of the body. One chronic illness that affects the Central Nervous System is Multiple Sclerosis. Roughly 2 million people througout the world have been faced with this disease‚ and “in the United States‚ it is estimated that 450‚000 people are affected‚ with 10‚000 new cases per year” (Goodman & Fuller 772).

Visceral motor is directed from hypothalamus and midbrain and is involuntary‚ but has input from cortex and thalamus. Somatic lower motor neuron is in ventral horn of gray matter and neurotransmitter at skeletal muscle is Ach. Visceral motor comes from

I bought the mints and so far‚ I have enjoyed them without having the urge to use chew them or have them one after another in one day. For example‚ today I had a mint after lunch and then another one when I got out of work‚ while driving home. It felt normal‚ and I was satisfied after I finished it. I did not feel like I wanted another one. My family thinks it is a good idea‚ so I have their support. It has been three weeks without the negative behavior and I feel I am forgetting about it.

The nervous system is one of the smallest yet one of the‚ if not the most‚ complex systems in the human body. It can be broken down into two main subdivisions‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system contains about 85 billion neurons and includes the spinal cord and brain. It is considered the control center of the body and processes all types of incoming sensory information. The peripheral nervous system is composed of all the other tissue

The job of the central nervous system is to process and send information to the peripheral nervous system. The nervous system consists of the brain‚ spinal cord and a complex network of neurons. The central nervous system is responsible for receiving‚ sending and interpreting information from the whole body. The nervous system also monitors and coordinates internal organ functions and responds to external changes as they occur. The two main organs of the central nervous system are the brain and spinal

(Davidyan‚ 2017) The parasympathetic nervous system decreases the blood pressure as well as heart rate through vagus nerve. The diameter of the blood vessels is regulated by the vasomotor system. Vasomotor nerves made up of sympathetic motor nerves transmit impulses to the vasomotor center to innervate smooth muscles in arteries which maintain a vasomotor tone to bring
