Sensory system

a minor brain bleed and a small concussion In first grade, I had surgery to fix up my brain and skull. All of these injuries took a major toll on my brain. The brain makes up part of your central nervous system (CNS) along with the spinal cord. It works along with the peripheral nervous system (PNS) to carry out everyday functions. The PNS is made up of nerves that run all along your body. Nerves reach all around…

However, the individual who is vaccinated against the varicella virus may actually have a mild case of the chicken pox because the vaccination has a small amount of the virus in it. This process is called an attenuated virus this will help the immune system recognized the virus and begin to build antibodies against it. The varicella disease occurs all over the world (Centers for Disease Control, 2016) and in temperate climates. The most cases are during the spring months this trend has also…

Introduction Multiple Sclerosis (MS) is a chronic disease that affects the nervous system. It is primarily an inflammatory disorder of the brain and spinal cord. People diagnosed with MS may have a variety of symptoms that can include: weakness, tremors, tingling, numbness, loss of balance, vision impairment, paralysis, impaired thinking, neuropathic pain, and bladder or bowel problems. Patients may also experience memory loss and depression. There is no current cure for MS, but there are…

the vestibular, visual and proprioceptive systems. Motor output is relayed through two separate pathways in response to the integration of the information. Thus, making it clear that a multitude of different systems comes together to maintain balance at any given point in time. The vestibular system plays a key role in maintaining a sense of balance in the body. It is a whole system dedicated to coordination, balance…

behaviour, your coordination, your smell, and your personality. The second lobe is the parietal lobe; it processes information like pain, pressure, touch, and how to judge distances. In the parietal lobe there is two Cortexes, the sensory cortex and the…

The nervous system is composed of two main parts which are the central nervous system and the peripheral nervous system. The central nervous system includes the brain and nerve cords like the spinal cord while the peripheral nervous system includes the motor nerves and sensory nerves. There are two main types of support cells in the nervous system which are glial cells and neurons. The neurons' function in the system is to receive and send electrical signals. The glial cells provide insulation…

affects their ability to think, but it also causes people to learn at rapid speed. “The human brain is one of the most complex organs in the human body. It is protected by our skull and tissue” (Webmd). The brain is the center of our nervous system and it sends signals all throughout our body. As advanced as science is today, doctors and scientist still have many questions about the human brain, only having limited answers. “The brain made up of specialized functions that work together, and…

response to an unpleasant stimulus (Fig. 1). Pain guards a living organism by telling the brain to back off from an approaching threat or something dangerous. Pain is subjective and difficult because it has both an affective and sensory component (Pain). The rest of the nervous system pain reception is created before…

emotions occur in the limbic system. The limbic system is one of the less evolved system of our brains that came after the development of the “old brain”. This small portion of your brain is vital in perception of emotions. The Hippocampus, Thalamus and Amygdala are two parts of this system whose main purpose is to control emotion. The hippocampus is in charge of memories, and how we perceive them , the amygdala is responsible for perceiving fear, and the thalamus processes sensory data. All of…

Neurological Factors Affecting Movement Voluntary human movement is regulated and controlled by complex interactions within our central and peripheral nervous systems. The three major types of sensory input come from the visual (eyes), vestibular (inner ear), and somatic (body) sensory systems. The somatic sensory receptors found in muscles, tendons, ligaments, joint capsules, and skin are collectively known as proprioceptors and they gather information about body position and the direction and…
