Central nervous system

the 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…

The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

A 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…

1 Central Nervous System Communication As stated by the website, umaine.edu, agenesis of the corpus callosum is a rare birth defect, a lifelong brain abnormality, in which there is a complete or partial absence of the corpus callosum. This occurs when the corpus callosum, which is the band of white matter connecting the two hemispheres in the brain, fails to develop normally, typically during pregnancy. The types of behavioral changes that would occur because of this failure to develop are…

The central nervous system is crucial to human function; it consists of the brain, spinal cord and a network of nerves moving to the rest of our body. It controls everything in the body e.g. emotions, senses, responses, reactions, body balance like temperature and heartbeat as well as movement of our muscles and glands. The CNS (Central nervous system) covers the brain and spinal cord where the PNS (Peripheral nervous system) is made up of the nerve fibre’s that branch off from the spinal cord…

The human body consists of two nervous systems: Central Nervous System (CNS) and Peripheral Nervous System (PNS). The CNS consists of the brain and the spinal cord, whereas, the PNS consists of nerves outside the brain and spinal cord. The PNS connects the rest of the body to the CNS. The PNS are grouped into two categories, sensory (afferent) nerves and motor (efferent) nerves. Sensory nerves convey information from receptors to the CNS. Motor nerves convey information from the CNS to the…

The Nervous system is one of the most important parts of the body. It connects all other organs to help them communicate together. This system is made up of the brain, the spinal cord, sensory organs, and nerves that connect organs together. When all of these parts work together, they have control of the body. The brain and the spinal cord are two major organs that make up the central nervous system. The nervous systems relationship with the other systems is giving them the right information…

The first main system is the central nervous system which consists of the brain and the spinal cord. There are three main sections of the brain; the forebrain which contains the cerebrum and the parts of the diencephalon (the thalamus, hypothalamus, and epithalamus most importantly), the midbrain which is a part of the brain stem, and the hindbrain which consists of the medulla oblongata, the pons, and the cerebellum. The cerebrum, the picture on the right hemisphere of the model’s brain, is the…

Multiple Sclerosis is a chronic, progressive, degenerative disorder of the central nervous system. This disorder usually affects young adults between the ages of 20 and 40. Multiple frequency of occurrence is rare, .1% currently afflicts about 400,000 in the United States and 1 million worldwide. The cause of multiple sclerosis is unknown, but it is likely that multiple factors act in concert to trigger or perpetuate the disease. It has been hypothesized that multiple sclerosis results when an…

Summary: Dopamine is a neurotransmitter that activates different dopamine receptors throughout the central nervous system. As mostly invertebrates have been studied in the past, the researchers wanted to focus on vertebrates in this study in order to determine the evolutionary patterns of these receptors. Five dopamine receptor genes were studied in five different mammals, and it was discovered that genes that are expressed more broadly have slower evolutionary rates than genes that are…
