    The nervous system is 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 Peripheral nervous system. The Central nervous system is made up of the brain and spinal cord and The Peripheral nervous system is made up of the Somatic and the Autonomic nervous systems. The nervous system is responsible for coordinating all of the body 's activities. It controls not only

    Diseases of the nervous system Throughout life the nervous system remains plastic although some of its capacity does diminish with advancing age. Changes in the nervous system consist of a loss of sensory cells and neurons of the peripheral sensory organs. In particular there is a loss of sight, memory and hearing, but sense of equilibrium and joint sense also deteriorate with advancing age. As well as diminishing effect due to advancing age the nervous system can suffers from several diseases.

    10.1 STROKE This concept was taken from module 10 “Assessment of nervous system”, Sub-topic 3 “common abnormalities and assessment findings of nervous system”. Stroke is a condition of both the nervous and cardio-vascular system. Stroke is a condition of brain damage which results due to shortage of blood supply. The blood supply to the arteries of the brain is reduced leading to brain damage. This result from shortage of blood supply and glucose supply to the brain. In the US it is the fourth

    Stress can do many things to your body. It affects the nervous system, the heart and hormones just to name a few. Our body reviews all situations and decides whether or not it is stressful. This decision is made based on sensory input and processing and also on stored memories. The stress response begins in the brain. The hypothalamus in the brain is in charge of the stress response. When a stress response is triggered, it sends signals to two other structures the pituitary gland, and the adrenal

    Only VIP’s pass. Parasympathetic nervous system The parasympathetic nervous system is one of three divisions of the nervous system. The parasympathetic system conserves energy as the heart rate is slowed, increases intestinal and gland activity. John notices that when he is resting, his heart rate is lower than when he is active. This is the parasympathetic nervous system at work it is conserving his energy. Sympathetic nervous

    Sympathetic nervous system is the one that will be engaged. This is because; sympathetic nervous system normally functions to produce reflex adjustments and localized adjustments of the cardiovascular system. Under conditions of stress, activation of the entire sympathetic nervous system occurs producing the fight-or-flight response. What characterizes this response is an increase in heart rate, epinephrine release from the adrenal gland in large quantities, vasodilation of the skeletal muscle, cardiac

    The Nervous System Introduction Did you know that the nervous system is considered one of the most complicated system in the human body? Without the nervous system, none of the other systems would function optimally. The nervous system is responsible for the control of and communication between different parts of the body. It interprets the things your body senses and sends the information to the muscles and glands, telling them what to do. It also takes care of the systems you do not think

    The central nervous system and the peripheral nervous system are the two main components of the nervous system.The central nervous system are made up of the brain, spinal cord, and nerves. There are three types of nerves sensory, inter, and motor nerves. The brain is the “Boss” of an Organism 's body everything is sent to the brain. The nerves are the “workers/messengers” they send the messages to the brain to make sure that everything is ok with it. The spinal cord is the pathway to give the brain

Sexual arousal and appetite are taken care of by the Parasympathetic nervous system. The parasympathetic nerves act as a brake system in the fight or flight response. If you are threatened, the “brake” is removed in order for the survival system to facilitate fight or flight behaviours. The parasympathetic nervous system is also the centre

    The nervous system consists of two divisions; the central nervous system and the peripheral nervous system. The central nervous system is the combination of the nerves within the skull and spine, while the peripheral nervous system is the nervous system that goes everywhere inside (autonomic nervous system) and outside (somatic nervous system) around the body except skull and spine. The somatic nervous system has two kinds of nerves; afferent nerves that carry sensory signals from the external

    The nervous system is the body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) are made of nerves. The brain is made of three main parts which are the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus. The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons, and medulla. Often the midbrain, pons, and medulla

    The nervous system is made up of two systems that work together to help the body function. One of the systems is the Central Nervous System (CNS) which consists of the spinal cord and the brain. The other system is the Peripheral Nervous System (PNS) which is made up the nerves that connect to the rest of the body. Working together they both contribute to the wonder known as the nervous system, but how? (Better Health Channel, 2014). As said before, the Nervous system is made up of two systems, CNS

    A. Theoretical Background: The nervous system is categorized into two different divisions: The central nervous system (CNS) and the peripheral nervous system (PNS). The CNS mainly consists of the brain and spinal cord. The PNS consists of the nerve impulses that carry synapses to and from the spinal cord. It includes the cranial nerves such as ganglia, enteric plexuses and sensory receptors. The PNS can also be divided into the somatic and autonomic nervous system, which is divided further into the

Firstly there are neutrons which re considered to be the building blocks of the nervous system. These neutrons are surrounded by another type of cell known as Glial cells. While the neutrons are the building blocks, these cells are the scaffolding, and therefore add structure to the pervious system. As a consequence, there are ten times as many

    The Nervous System The Central Nervous System (CNS) consists of the brain and the spinal cord. It acts as the body’s control center and coordinates body’s activities. Nerve cells, called neurons, send signals in the body that travel through impulses to reach their destinations. The CNS contains specific neurons called interneurons that transmit impulses between other nerve cells. Peripheral Nervous System (PNS) consists of all the nerves in the body that are not in the brain or spinal cord. These
