Nervous system

Introduction With each case study, I will explore and analyze the various scenarios and the impact the ailments have on the nervous system. Each scenario has its own effect on areas of neurons, the method of sending and receiving neurotransmitters, and the lasting effects of the impaired neurons. Case Study 1: Amy Amy burns her finger while cooking dinner. The natural response for someone that touches something hot is to pull their hand away from the heat. This response is provoked by general…

those they later reside in. The Nervous System is the master controlling and communicating system of the body. Electrical impulses act as signaling device; they are rapid, specific and cause immediate responses. They also use sensory receptors to monitor changes called stimuli. This is where gathered information creates sensory input. Integration is the processes and interprets sensory input which affects a response and creates motor output. Central Nervous System (CNS) consists of the brain and…

Retina is apart of the Central Nervous System. The Retina is how people are nearsighted they can see they can see near objects, but they can’t focus enough to see far. Farsightedness or being farsighted is when you see far, but you can’t see near objects clearly. The 130 receptor cells are also known as rods and cones. The Central Nervous System is apart of the Nervous System, but the Central Nervous System makes up the brain, spinal cord, and retina. The Nervous System is a collection of…

1. Neurons are the building blocks of the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal…

There are two sections within the peripheral nervous system, but we’ll specifically review the autonomic system which controls involuntary muscles. These muscles are the smooth muscles found in structures such as blood vessels, airways, glands, and cardiac muscles within the heart. This system also regulates numerous functional characteristics such as blood pressure, heart rate, respiration rate, digestion, and sweating. Additionally, the autonomic system is divided into two subdivisions known…

the Brain, Nervous System, & Sensory Systems In humans, the nervous system is the area in which the body processes and sends messages. It is a complicated system that gathers sensory information from the entire body, replies to changes in the body, evaluates request information, begins and implements all bodily activity, and preserves “homeostasis” in the body. An organism nervous system is separated into two systems: the “central nervous system (CNS) and the peripheral nervous system (PNS).”…

The nervous system in the body is divided into Central Nervous System (CNS) and Peripheral Nervous System (PNS). Central nervous system controls all important nerves inside the body enable the body to do its daily tasks. Peripheral nervous system is the system that control on the outside the brain and spinal cord. Both systems are requiring in the body for different functions. The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and…

afternoon around 2:30, you 're just sitting at home watching television and life is slowly just passing you by. Even as drift slowly into a stagnant and passive state, your brain is still constantly at work using apart of the nervous system called the automatic nervous system . Your brain is one of the most important parts of your body, it tells every other part of your body what to do, whether we are aware of it or not. So as you sit idle on your couch staring into a picture box, your brain is…

come together make up the four main systems in the human body. These systems intertwine and jointly work together for a person to eventually phonate, breathe, or just walk around a room. The processes for a person to produce the word "deep" requires copious amounts of organs with these different systems to work together to produce the syllable. The nervous system involves the brains and all the nerves, even all the way down to the spine.…

Glial Cell is a non-neuronal cell that maintains homeostasis from myelin and it also provides support and it provides protection from neurons in the central nervous system. Glial cells also provide support and protection for neurons in the peripheral nervous system. Glial cells are known as being in large quantities in the central nervous system. Glial cells are very different form nerve cells. They differ in the way that they do not participate in synaptic interactions and electrical signaling.…
