Sensory system

The body and mind undertake many activities. However, these activities are mostly controlled by the central nervous system (CNS). The brain and the spinal cord are the main components of the central nervous system. The brain is divided into three portions: the hindbrain which houses units of the brain that controls heart and sleeping patterns, the midbrain which links the forebrain to the hindbrain and also controls the heart rate and sweating, and the forebrain which controls our voluntary…

those people found out that pain is one of the most essential pieces to life. Not only does the nervous system benefit the body in many ways, it senses pain and sends a message to the brain that a part of the body is experiencing pain. The brain has millions of neurons to help identify different situations that occur from anywhere at the top of the head to the bottom of the toes. The nervous system and brain of a person work together tremendously to leave people wondering how pain works, why it…

Biomphalaria glabrata is a freshwater snail that originates from Central and South America. The NMRI strain of Biomphalaria glabrata exhibits albinism. The snails’ albinism makes them transparent, which provides the opportunity to observe their circulatory anatomy and physiology. They lay eggs in masses, with 2-30 eggs per mass. The eggs go through several developmental stages. First, they are fertilized. Each egg contains a single embryo, which then begins to grow. Each embryo measures…

The body is made up of many systems working together as a whole and the most significant one is the nervous system. The nervous system is responsible for making sure the rest of the body does what it needs and without this elaborate electrical system the body would have no meaning. There are many components to this beautiful labyrinth of nerves that allows us to be the marvelous humans we are. This system is complicated in itself but broken down into its peripheral, somatic, autonomic, and…

Hidden Dangers A list of pros and cons can be assigned to everything, unfortunately, computers and cell-phones, though amazing, are not exempt from this. Cons can refer to many things, but the one biggest downfall that is worth looking into is the unforeseen impact that technology has on the human body. The three main parts of the body that are being affected negatively include the eyes, brain, and neck/back. The latest and greatest technology seems to be what everyone wants to get their hands…

that connects directly to the neural system. Some possible use for brain implant technology are treatment for brain disorder, restoring and enhancing of sensory system, and augmenting brain processing. In this paper, the ethical considerations of applying brain implant technology for both therapeutic and enhancement purpose will be examined. Overview of brain implant technology Brain implant technology stimulates or receives electrical activity of nerve system through electrodes on microchip…

of the central nervous system and it can be classified into the hindbrain, midbrain, the forebrain and the brain stem right below the brain. Inside the midbrain, there is the cerebral cortex which consists of the temporal, occipital, parietal and frontal lobe. Their functions are processing auditory information; processing visual information; processing sensory information and order complex cognitive behaviours respectively. Same inside the midbrain, there is the limbic system which consists of…

Neuropathic pain whether based on an injury or a result of a form of dysfunction from the nervous system is still a condition which better treatment options are still being researched. Neuropathic pain can even be divided further into peripheral and central neuropathic pain. While peripheral pain may result from a disease, a more central neuropathic pain may result from damage to brain or spinal cord. [] Despite numerous medications in the market and therapy treatments which patients endure,…

Relapsing-Remitting MS (RRMS). Around 10% have Primary-Progressive MS (PPMS), there is also Secondary-Progressive MS (SPMS), and Progressive-Relapsing MS (PRMS). The least common type is PRMS. In MS your immune system mistakenly attacks the myelinated axons of a nerve fiber in the central nerves system, over time this leads to scarring and hardening of nervous tissue in the brain, spinal cord and eyes. Every hour of every day someone in the United States is diagnosed with MS. Most people do not…

the damage to one or more of your peripheral nerves. This affects messages traveling between the central nervous system and the peripheral system. There are several conditions that may lead to peripheral neuropathy. Diabetes is the most common cause of chronic peripheral neuropathy. The sign and symptoms of peripheral neuropathy depend on which type of peripheral nerves are damaged (sensory, motor or autonomic nerves). Neuropathy can affect one or a combination of all three types of nerves. Of…
