Explain the origination and functions of the nervous system Introduction of Nervous System The nervous system is a network of nerve cells that communicate to the brain by sending electrical and chemical impulses. The nervous system deals with fast responses of the body and are often short term. There are two main parts the nervous system. The first part is the Central Nervous System (CNS) and it is found in the brain all the way down the spinal cord. The CNS is the part that receives the…

Antiemetics Overview: Antiemetics are used for nausea and to prevent vomiting and also used for motion sickness. These drugs can be bought over the counter. (OTC) Action: Dimenhydrenate or Dramamine is an antihistamine. It should be taken one hour before travelling, and will prevent motion sickness.

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…

information about the nervous system, the neurons, the brain, the endocrine system, and genetics and behavior. The nervous system helps the body carry vital information from and to the brain. The brain can adapt to certain environments and can change depending on the environment that you are in and your way of thinking. It can spread information with the help of neurons, who pass information from one neuron to the next. There are two different pathways in the nervous system the afferent and…

The nervous system makes it possible for animals to know and react to the environment around them. A change or event that evokes a specific functional reaction in an organ or tissue is a stimulus. There can either be an internal or an external stimulus. Internal stimulus being something like hunger or pain, while external is more along the lines of a sound or an odor. The nervous system interprets stimuli and orders other organ systems to respond. The nervous system does so through using sensory…

The spinal cord is ¾ of an inch wide and 42-45 centimeters in length. It extends inferiorly from the medulla oblongata to the inferior border of the L1 vertebrae. The spinal cord is divided into 5 parts that house the 31 pairs of spinal nerves. The cervical part is the superior part of the spinal cord. It contains neurons whose axons contribute to the 8 pairs of cervical spinal nerves. The thoracic part lies inferior to the cervical part. It houses the neurons for the 12 pairs of thoracic spinal…

no:16472374 The nervous system and neuron communication The nervous system is a highly complex and broad area of biopsychology. People depend on the nervous system for their survival and safety.This essay will explore the components from which the nervous system is composed and their main functions. This essay will also decipher the mechanisms through which neurons communicate. According to Carlson (2014) the Nervous system is branched into two categories - the central nervous system (CNS)…

The central nervous system consists of the brain and the spinal cord and is responsible for the majority of the functions of the body and mind (What is the Central Nervous System?). The brain and spinal cord contain two types of tissue, grey matter, which originates and processes nerve impulses; and white matter, which transmits them (Structure…

The main three sections of the brain are the hindbrain, the limbic system, and the cerebral cortex. The hindbrain consists of the medulla which is directly above the spinal cord and controls breathing, heartbeat, and other vital life functions like the things we don’t have conscious control over. It also has pons which…

treatment that Reflexology offers uses points on a person’s hands and feet to help eliminate stress and tension. It has been shown that when people are under a large amount of stress, the autonomic nervous system becomes induced (Hughes et al, 2011). Reflexology helps to maintain the autonomic nervous system by reducing stress and anxiety. Reduced levels of stress and anxiety are found to help women who have depression, people who have or have had cancer, and any working professional (Hughes et…
