The nervous is considered to be the master controlling the systems of the body. The way it does this is to communicate through nervous impulse which is very rapid and very specific. The nervous system consist of the peripheral nervous system (PNS) and central nervous system (CNS). The peripheral nervous system consists of the cranial nervous, spinal nerves and ganglia. The peripheral nervous system can also be broking down into two categories which are somatic nervous system and parasympathetic system. On the other hand the central nervous system includes the brain and spinal cord. (fleming-Mcphillips, 2011)

The nervous systems also consist of neurons which are a nerve cell that carries out the functions of the nervous system by sending and receiving impulses. Another neuron that I have learned about would be motor neurons these neurons are very important because they help muscles to contract and gland secretion, these motor neurons are also known as efferent nerves. The efferent neurons give impulses from the neural cell body to the target muscle or organs. Motor neurons also have a process called the axon and dendrites that extend away from it in vary directions. Neurons usually have several dendrites and only one axon. (fleming-Mcphillips, 2011)

The axon is covered in a fatty insulting substance called the myelin sheath. Axon can be several feet long and can reach from the cell body to the area being activated. Dendrites are like tree branches that are unsheathed. Another neuron that’s in the nervous system is the sensory nerve also referred as afferent nerves. This neuron transfer sensory information through the peripheral process. This is the process where impulses are sent to the central nervous system. (fleming-Mcphillip...

...her cortical areas. It plays a role in voluntary and involuntary motor control and is located between the midbrain and medulla oblongata. (fleming-Mcphillips, 2011)

Lastly the medulla oblongata where nerve centers vital the body survival has control over circulation of blood by regulating the heart beat and arterial blood pressure. The last part of the nervous system would be the spinal cord which extends from the base of the medulla oblongata to the junction between the first and second lumbar vertebrate. Its functions are to conduct sensory impulses from the rest of the body to the brain and send impulses from the brain to the body. (fleming-Mcphillips, 2011)

The nervous system plays a major row in human bodies as you can see. I can conclude that without a nervous system we would be in dangering our selves all the time because we wouldnt be able to feel thing.

Anatomy and Physiology of the Nervous System Essay

- The body is a physical structure composed of the skeletal, muscular, endocrine, digestive, circulatory, respiratory, excretory, and the one I am representing, nervous, systems, yet the most priceless and vital one that surely should not be laid off is the nervous system. The nervous system consists of two sections. The first is the central nervous system (CNS). The CNS, which coordinates the activities of the entire nervous system, is composed of the brain (cerebrum, cerebellum, and medulla), and the spinal cord that is connected, via the brain stem, to the brain; nerve cells carry impulses from it....   [tags: brain, control, nerves]

A Study Of Nervous Systems, Anatomy And Physiology Essay

- Question 6-The approach that fascinates me the most is neuroscience; furthermore, neuroscience is the study of nervous systems, anatomy and physiology. Neuroscience is preoccupied with both the organization of the system in humans, animals and their purposes. Neuroscience proposes a body of information that serves as an infrastructure for comprehending how cognitive operations are conveyed. Cognitive neuroscience focuses on cognitive processes, which are visual, object recognition, attention, memory, problem solving and language (Friedenberg and Silverman, 2012)....   [tags: Human brain, Brain, Nervous system]

- ustin Youssef Anatomy and Physiology Paper #4: Nerve Anatomy The nervous system is an imperative part of the human body that assists in the transmission of signals across several different parts of the body. It also releases messages back and forth from the brain to the different parts of the body and coordinates the voluntary and involuntary action of the body. At the cellular level, the nervous system consists of a cell called a neuron, also known as the nerve cell. The neurons connect via synapses that act as a pathway connection that transmit signals to other cells....   [tags: Nervous system, Neuron, Spinal cord, Nerve]

How The Nervous System Affects Our Body With Our Daily Lives Essay

- Introduction "Those who think they have no time for bodily exercise will sooner or later have to find time for illness." Edward Stanley. The present paper reviews the benefits of exercise in the functions of older adults within the nervous system. It will also discuss the anatomy of the nervous system and how it affects our body with our daily lives. Anatomy & Physiology The nervous system is organized to detect changes in the internal and external environment, evaluate that information, and possibly respond by initiating changes in muscles or glands.1Neurons are the basic unit of the nervous system and are made up of excitable cells that conduct the impulses that make it possible for all...   [tags: Nervous system, Peripheral nervous system]

The Anatomy And Physiology Of The Human Muscular System Essay

- The Complexity of Muscles The human muscular system, like any other system in the human body, is very complex. All the moving parts (anatomy), and how they work together to perform specific actions (physiology). There is so much that can be done to help the muscles in your body perform strenuous activities before fatigue, before your muscles run out of the fuel required to continue to perform movements. The biggest question most young adults want to know is, how do you get bigger muscles. Or, why do I cramp during workouts....   [tags: Muscular system, Muscle, Muscle contraction]

The Nervous Systems Essay

- The processes of communication between distinct tissues and organs Among various types of organ systems, the nervous system is one of the most important one in human body. It is responsible for producing, controlling and guiding our thoughts and responses to the world around us according to James W. Pennebaker (2012). During embryological development, the cells that form nervous system are incredibly specialised and work complexly than the cells that form skin or other body parts. Neurosecretory cells are one of the examples of specialised nervous system cells that produce neurosecretions....   [tags: anatomy, nervous system]

- The human body is a single structure, made up of trillions of smaller structure. The study of the human body entails both anatomy and physiology because of the structures and functions. (Roberts, 2014) Anatomy is “the study of the structure of the body and the physical relationships involved between body systems” (Ross and Wilson, 2006). Physiology is a subsection of biology that deals with the organs, structures and how it integrates with the human body to create life. Anatomy and physiology are interwoven and its function depends on its structure and form....   [tags: Digestion, Metabolism, Respiratory system, Blood]
