The Nervous Systems Essay

Nervous System and Diseases Within 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)…

Nervous System- Nerve Impulse When a stimulus is strong enough, a nerve impulse is generated in an "all or none" response which means that a stimulus strong enough to generate a nerve impulse has been given. The stimulus triggers chemical and electrical changes in the neuron. Before an impulse is received, a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number of sodium ions present compared to…

The nervous system is critical for human survival. The human nervous system is responsible for signaling bodily functions, sensory experiences, and information processing. The nervous system consists of three major structures: the brain, the spinal cord, and the peripheral nervous system (Brodal 1-18). The brain, spinal cord, and peripheral nerves are responsible for different processes and have unique structures. The brain is divided into three substructures: the cerebrum, cerebellum, and brain…

& function of the Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart, stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs…

Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body's activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their…

There are two major subdivision of the nervous system, the Central nervous system (CNS) which consist of the brain and the spinal cord and the Peripheral nervous system(PNS) consisting of the neutral tissues outside the brain and the spinal cord. The Central Nervous System integrates and coordinates all bodily functions, process all incoming messages and send commands to different body parts. Sending and receiving messages through the spinal cord and the part of the spinal column called a trunk…

Cocaine and the Nervous System All drugs have a negative effect on the nervous system, but few can match the dramatic impact of cocaine. Cocaine is one of the most potent, addictive, and unpredictable recreational drugs, and thus can cause the most profound and irreversible damage to the nervous system. The high risk associated with cocaine remains the same regardless of whether the drug is snorted, smoked, or injected into the user¡¯s bloodstream. In addition to the intense damage cocaine…

Introduction: The central nervous system (CNS) is the system within the body that is under scrutiny during this case. The CNS is split into two sections, the brain and spinal cord and these two separate sections are made up of white and gray matter (Silverthorn, 2013). White matter is made up of myelinated axons, allowing for fast transmission of nerve signals, while grey matter is unmyelinated nerve bodies (Silverthorn, 2007). The specific part of the CNS that is of interest is the brain. The…

The Nervous System The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous…
