The central nervous system is composed of our spinal cord and brain which consistently controls our mind and behavior. The complexity of our brain is not entirely deciphered, but with extensive scientific research it can be concluded that each specific section has its own specialized function. In reference to eating pizza, socializing, and playing a game of cards, it can be deduced that our central nervous system is always critically analyzing data using our Broca’s area for speech, hippocampus
The central nervous system can be compared to the air traffic control tower of a large international airport. Just as this main tower directs and controls all incoming and outgoing flights. The central nervous system is the control center of our body, it sends information out and interprets things our body senses. Regulating, controlling and coordinating incoming and outgoing impulses, thoughts, and feelings via nerves. Functionally, the nervous system can be divided into the central nervous system
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
Generation of pattern and diversity in Central Nervous System Central nervous system (CNS) is composed of brain and the spinal cord. Neurons constitute a major part of the developing CNS. An axon is an extension of a neuron. The brain grows as a swelling at the front (rostal) end of the neural tube and later leads to become a spinal cord (1,2). Development of the CNS involves many complex mechanisms beginning at the onset of transformation of a single layer of ectodermal cells, the neuroectoderm
The Neuron The central nervous system is one of the most important systems in the human body, and at its core is the neuron. Neurons are cells that facilitate the transmission of electrical signals throughout the body. They allow the nervous system to act as a communication network that runs throughout the entire body. Without neurons, the brain could not tell the rest of the body what to do. Neurons come in various shapes and sizes; however, they all share the same basic structure. Additionally
THE CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors, as well as our thoughts and feelings, are produced by the actions of our brains, nerves, muscles, and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being, including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it
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 above process to neuronal regeneration takes place both in the peripheral and central nervous system however, a number of factors are present in the CNS for example Spinal cord injury causes a rapid stop of regeneration of damaged axons. The site of a spinal cord injury as a result of the phenomena occur eventually to produce a cavity filled with liquid syringomyelic CSF and covered with a layer of glial scar. This scar and cavity form a loss of continuity of long nerve pathways of the spinal
control network for the body’s functions and abilities to do work. Both the brain and spinal cord comprises the body’s Central Nervous System (CNS) and empowers conscious communication with the body and also helps perform vital operations such as breathing, releasing hormones, and maintaining blood pressure. The Central Nervous System (CNS) works along with the Peripheral Nervous System (PNS). According to the Canadian Cancer Society, “PNS is made up of nerves that branch out from the spinal cord to
When the membrane potential is excited, the arrival of an action potential at the synaptic knob allows the neurotransmitters released into synaptic cleft to trigger an action potential in the postsynaptic neuron (McCance & Huether, 2014). The central nervous system CNS is the main control center of the body that receives sensory input, organizes and synthesizes it then provides instructions for motor output to the rest of the body. It constitute of the brain and spinal cord. The brain consist of the
