Peripheral nervous system

neurons, or nerve cells, to pass along information. Normal body function indicates that as the extremity (upper or lower extremity) receives a stimulus, an electrical impulse is sent through the appropriate nerves within the peripheral nervous system to the central nervous system via the spinal cord, and up to the brain to be processed. Depending on pain or other…

the parasympathetic division of the autonomic nervous system The autonomic nervous system (ANS) is a part of the peripheral nervous system that largely acts involuntarily. It consists of nerves in cardiac muscle, smooth muscle, exocrine and endocrine glands. The main visceral activities are temperature regulation, digestion, blood pressure and genitourinary function. The second main division of the peripheral nervous system is the somatic nervous system. This consists of cranial and spinal…

The nervous system is constructed of several divisions; the central division and the peripheral nervous system. The central nervous system includes the brain and the spinal cord, including various centers that join the sensory and motor information in the body. These centers are separated into low centers that carry out crucial body and organ control functions and higher center within the brain that control more information processing. The peripheral nervous system is subdivided into…

connect to the spinal cord, which runs up the spine of a human, attaching to the brain. This makes up the nervous system, one of the most crucial systems in the human anatomy. Though it may seem like a small system, it is detrimental to the health of individuals. Many things can go wrong in the nervous system, causing a person to call upon neurosurgeons. Neurosurgeons work with the nervous system accumulating a high salary and knowledge as their career progresses, and are essential to the world…

Neurons are not the only cells that occupied the central nervous system (CNS). In fact, neurons are outnumbered by supportive non-excitable cells, collectively called neuroglia (a.k.a. glia). The term glia was coined by Rudolph Virchow in 1859 to indicate the “connective tissue” surrounding the neurons (glia came from Greek meaning glue). However, the combination of the activities of glial cells and neurons is crucial for brain functions (Steward 2000). There are three types of glial cells in…

had 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…

Michael Phelps, Serena Williams, Usain Bolt and Louis Zamperini have one thing in common: a unique nervous system. What makes an olympic athlete’s brain anatomy different from a regular athlete? What changes take place in their brain and its connecting peripheral nerves? And can anyone become an olympic athlete? The human body is capable of making changes to itself to adapt to different environments and specific tasks. Not only do the muscles in our body change but also our brain and certain…

interpret, store and use information. The nervous system is divided into central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and they are the decision makers of the body. Sensory information gathering and action transmission occurs in the PNS. The brain consists of approximately 100 billion neurons and it is the smallest building block in the brain. They connect and carry messages to and from the nervous systems. There are different…

by the nervous system. There are two parts of the nervous system the peripheral nervous system and central nervous system. The brain, spinal cord, and nerves is what the nervous system is composed of. Together they control all the duties of the body. When something goes wrong with a part of your nervous system, you can have issues with actions such as breathing,speaking,swallowing, and moving. It is effortlessly the generator of the whole organism and in the human anatomy it is the system that…

This essay is about the brain and the growth mindset. Did you know that the brain is the command center for the nervous system? Well yes, the nervous system is part of the brain. There are 100 billion neurons in our brain alone. The brain sends messages via the spinal cord to peripheral nerves throughout the body that serve to control the muscles and internal organs. The largest part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which…
