Nervous system

)The nervous system is a complex system our body uses to make decisions and perform actions. It is made up of cells called neurons and special cells called glial cells (or neuroglia). Neurons produce responses by generating action potentials. Action potentials are formed when graded potentials are summated at the initial segment (integrating center) of a neuron cell body. The action potential then propogates through the axon. The nervous system has two main branches: the Central Nervous System, and

revealed everyday. The brain is part of the central nervous system (CNS). Its role is to receive signals, decode the signals, and send response signals down the spinal cord to the rest of the body. Signals are received from different parts of the brain depending on which sensory organs receive stimuli (Carter, Gray 697). Once sensory organs receive stimuli, stimuli are transmitted to sensory memories, which are “physiological parts of the nervous system” [that directly sensors to the brain] (Kinster,

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)

The function of the sensory neuron is to carry around action potentials from a sense organ or receptor to the central nervous system. The structure of the sensory neuron has the sensory receptors, the structure of these are that they vary however they utilize the gated sodium ion channels which are present in the membrane. The function of these are that they are able to detect a change in the environment and they are able to create an action potential with sodium ions. The schwann cell wraps around

Nerves Dendrites- processes that send signals toward the cell body Cell body- part of a neuron that contains the nucleus and other organelles Axon- conducts nerve impulses along its entire length B. Location Nerves- all throughout the body CNS (spinal cord)- runs up and down the dorsal side Brain- in the cranium C. Primary function(s) Nerve impulses- the way a neuron transmits information Send information from

The nervous system of the human body can be separated into two parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The brain and the spinal cord make up the Central Nervous System, which is the nervous system’s processing center. The Peripheral Nervous System “consists of nerves that branch from the Central Nervous System and connect it to other body parts” (Shier, Butler, Lewis 2015). The somatic nervous system and autonomic nervous system are the subdivisions of the

Brain and Nervous System Aging is part of life, as we grow our body changes from the moment we are born we start developing and slowly start to age. The body organs and body system starts developing when we are in our mother’s womb and every day there is a change in our body. As people get older we start having health issues some are moderate but with time it is more likely that does issues will turn into health problems. Aging changes the nervous system, the brain and nervous are your body’s central

The organs of the nervous system can be divided into two groups. One group consisting of the brain and spinal cord, forms the central nervous system. The other, composed of the nerves ( bundles and axons) that connect the central nervous system to other body parts, is called the peripheral nervous system. Together, these systems provide three general function: sensory, integrative, and motor. The sensory function of the nervous system derives from sensory receptors at the ends of peripheral neurons

Understanding the Brain and Nervous System The brain plays an important role in regulating and controlling the body’s functions. In the brain there are billions of nerve cells or what can also be called neurons and support cells which are called glia. You can think of the brain and the nervous system as a computer and network. The brain is the computer and the nervous system is the network which sends messages from the brain to the body. The nervous system transmits the messages through the spinal

The human nervous system is complex one that is composed of two main parts: the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain and the spinal cord, that both serve different purposes. The brain intercepts and stores information as well as send actions to the muscles, organs, and glands. The spinal cords serves as a connecter for the brain and the peripheral nervous system. The peripheral nervous system is separated into two different
