94 Words1 Page
Recommended: Nervous System
The CNS, also known as the central nervous system, is the principle amalgamation system of the human body and is composed of the brain and spinal cord. In contrast, the PNS, also known as the peripheral nervous system, is composed of all neural tissue except the brain and spinal cord. These two systems work together, for example, sensory information makes its entrance into the CNS, which examines it and then transmits a motor reply via the PNS to muscular or glandular tissue. Furthermore, information arrives the CNS from the afferent division of the

1389 Words | 3 PagesThe human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.

A person can be left brained or right brained according to how they act.

Nervous System: The Most Common Cause Of Alzheimer's Disease
704 Words | 2 PagesThe Nervous System is the network of nerve cells and fibers that transmits nerve impulses between parts of the body. Can also be said that it's a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The nervous system includes both the Central nervous system and the peripheral nervous system. The Central nervous system is made up of the brain and spinal cord. Now the Peripheral nervous system is made up of the Somatic and Autonomic nervous systems. The Central nervous system is divided into two major parts which are the brain and the spinal cord. The brain lies within the skull and is shaped like
The Nervous System and Diseases
1259 Words | 3 PagesWithin the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the receptor and neurons and transferring nerve impulses to the cell body; furthermore, a cell body is composed of a nucleus, that works to provide energy and nutrients for the neuron; lastly is an axon, electrically conducted by the myelin sheath, the axon is a pathway nerve impulses pass through from the cell body. In addition, this is the process in which nerve impulses travel by to be able to access the rest of the system (Core Science, 2010). The correct function of the nervous system is vital to the daily survival of an individual, as it obtains a significant role in the control and co-ordination of the human body. Furthermore, if a situation occurs where the nervous system dysfunctions or develops a disease (such as multiple sclerosis), it would in that case threaten the current status of one’s health and cause havoc in the system.
Essay On The Nervous System And The Endocrine System
1106 Words | 3 PagesNervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural
The Human Nervous System
2573 Words | 6 PagesThe nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
Avatar The Last Airbender
617 Words | 2 PagesThere are countless television shows out there that connect to people on different levels, most of them being live action. Viewers of these shows will tell others it had to do with anything from realism to relatable traits found in various characters. One common thread that will most likely be shared between all of the choice is that being the show is not animated. However, I would argue that animated shows are just as good and even better than live action ones. One of the animated television shows that inspired me is Avatar the Last Airbender.
Understanding the Peripheral Nervous System and Fight-or-Flight Response
609 Words | 2 PagesThe body is made up of 11 biological systems that carry out certain functions. Each system must function properly in order for our body to survive on a daily basis. The nervous system is a communications device that receives, stores and processes input signals and responds in measurable ways to the kind and quantity of information delivered to it. The nervous system is broken down into two major systems. The two major systems are called the Central Nervous System (CNS) and the Peripheral Nervous System (PNS), but the system that will be significantly discussed is the Peripheral Nervous System. The Peripheral Nervous System is composed of Somatic and Autonomic. The Autonomic system is broken down into Parasympathetic system and the Sympathetic system, also known as the fight-or-flight response.
The Importance Of The Nervous System
963 Words | 2 PagesThe Nervous System is a network of cells that collects information about the organism’s internal and external environments, processes that information, and sends signal to effectors, muscles, and glands that are capable of responding to the information. It contains three important functions: receiving input from the environment, processing that information, and responding to the environment. The building block of a nervous system is neurons. They carry electrical signals and contain the dendrites, cell body and axon. Dendrite senses stimulation from the environment and sends that signal to the cell body, which contains the nucleus. The axon is a tube that is extended from the cell body and transmits the signal to other neurons or cells. Glial cells are located on the axon and act as a support
