-Increasing extracellular K+ reduces the net diffusion through the leak channels because if there are an increased amount of K+ ions outside of the cell, the amount coming from the leak channels needs to decrease so it can be balanced.…

Lidocaine is a local anesthetic. A local anesthetic is one that is injected or used at a specific site on your body, like eye surgery. Lidocaine can also be topical, or rubbed into the skin. Lidocaine blocks signals to the brain that are sent by nerve impulses or endings on the skin so the brain doesn’t receive the signal (Jahormi 2012). Lidocaine actually blocks the sodium channels of the cell membrane that are used for signal sending. Removing the cataracts of the eye or a specific skin disease could be treated with the use of Lidocaine. It is mostly used for a quick…
The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli, integrating and processing information, and generating output, it would be hard to survive without a nervous system; however, there are different types of nervous systems in various organisms. Humans, cnidarians, flatworms, and annelids all have very diverse nervous systems. There are similarities and differences in each of these beings.…

This activity will increase your understanding of the different structures of the nervous system and brain. During the Web activity, you will view a variety of structures of the brain and nervous system and label each with the appropriate term. You will use this document to write a description for the terms you used in the activity.…

For my reflection paper, I chose to give my opinion on the NBB’s, short for “Neurological-Based Atypical Behaviors”. NBB is defined as a collection of deeds or the behavior of children that happen outside the usual boundaries of self control.…
NERVOUS SYSTEM OUTLINE I. Nervous System = 2 Parts A. Central Nervous System (CNS) 1. Brain 2. Spinal Cord B. Peripheral Nervous System (PNS) 1. Nerves to parts of the body 2. Nerves from parts of the body C. Functions 1.…
Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…
The human Body is a very complex organism. It is composed of many different organs systems, which are vital for the body to function properly. They work with one another in order to carry out daily life activities and maintain the body’s proper functions. Among these organ systems lies one of the most important, the nervous system. The nervous system functions as the control center of the body, and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb, E.N. & Hoehn, K.). It helps the body communicate external environmental factors via electrical impulses that are transmitted through cells called neurons. These neurons can be up to a meter long and target a specific effector which it will help…
The divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).…
The purpose of this course is to provide the fundamental knowledge of the effects of environmental chemicals on living systems, and the toxic responses of the human and plant systems. Students will discuss risk, ethics, and social responsibility with regard to environmental toxicology.…
Another point about the negative effects of pesticides is that they harm animals and have some extreme impacts on their health and the survival of the species. In a journal on how the use of pesticides endangers wildlife and the environment, prominent author, investigative journalist, and science reporter Sonia Shah explains that seemingly benign levels of pesticides impair immune function in wildlife, leading to outbreaks of disease. In recent die-offs, millions of amphibians, bees, and bats died, decimating the populations (Shah, 1). Shah describes how it does not take an exorbitant amount of agrochemicals to harm an animal. When an animal’s immunity is compromised due to pesticide exposure, its body loses the ability to resist diseases,…
PETA also stated that “more than 100 million animals every year suffer and die in cruel chemical, drug, food, and cosmetic tests as well as in biology lessons, medical training, exercises, and the curiosity- driven medical experiments at universities.” These experiments sometimes cause the animals that are being tested to have neurotic deficiencies causing them to act differently from when they were…
