Neuron Essay Examples

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 […]

1. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface […]

Considered to be an autoimmune disorder, MS attacks the myelin sheaths which surround and protect the nerve fibers. The affected myelin then forms scar tissue (hence the name), also referred to as plaques or lesions, which can damage the nerve fibers and disrupts the transmission of nerve impulses from the CONS (brain and spinal cord) […]

The terms ‘seizure’, ‘spasms’, and ‘epilepsy’ are used interchangeably to refer to the same event. Abnormal electrical activity in the brain causes seizures, resulting in behavioral changes. These changes can include unconsciousness and body shaking. Seizures may occur due to developmental issues, infections, tumors, or metabolic problems. To better understand seizures, it is crucial to […]

The spinal cord, which is 43cm long, is encased in the vertebrae and is the main communication cable between the CNS and the PNS. ‘The nerve fibres running from various parts of the body to and from the brain are gathered together in the spinal cord, where they are protected by the bony spinal vertebrae.’ […]

In an experiment involving a blind individual named Guarniero, the aim was to determine whether our eyes or brain process images. To do this, Guarniero was connected to a chair with a pad covered in bumps that replicated the shape of objects. Attached to the chair was a camera that captured images and transferred them […]

April 1956: The pharmaceutical company Parke & Davis first synthesize what they believe to be the perfect anesthetic (Souza, 1995). When administered to patients, it causes a completely dissociative state, with no significant respiratory or cardiovascular depression. Patients appear to be awake, eyes open, breathing normally but are unaware of their surroundings or the procedures […]

Vertebrates have a spinal column or backbone. They possess two types of neurons: Peripheral Neurons, found outside the spinal column, and Central Neurons, located within the spinal column and head. i) Peripheral Neurons include: a) Efferent Nerves – these transmit signals from central nerves to effector organs. b) Afferent Nerves – these transmit signals from […]

Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the […]

In 1938, Dr. Albert Hoffman accidentally discovered the psychedelic effects of d-Lysergic Acid Diethylamide-25 (LSD). Psychiatrists in the 1950s and 1960s used LSD for analytic psychotherapy, believing it could help patients release repressed material and gain insights into mental illness through self-experimentation. By the late 60s, LSD became popular as a recreational drug. While its […]

Danny, a kindergartner, is constantly active during playtime. He frequently changes chairs, swings his arms and legs, and plays with the light switches by repeatedly turning them on and off. His constant talking irritates those around him. Even when his teacher suggests that he join a group of children playing in the playroom, Danny interrupts […]

Communication is the process of sharing information or ideas between individuals or groups. Communication takes place in different contexts, such as phone conversations or face-to-face discussions, where information is exchanged between different locations. Similarly, within the human body, information transmission plays a vital role in decision-making and action execution. For example, when an individual touches […]

Drugs some use them to escape pain, others use them for pleasure, and some use them to just fit in. Either way drugs are a harmful substance that may seriously affect the body. Drugs mess with the brain in ways that we couldn’t even imagine. From destroying brain cells that help with critical thinking to […]

The article provides detailed mechanism of how state of mind is interconnected with processes taken place in the human body. The article is of great importance for psychologists and physicians as it thoroughly examines the issues. The article is subdivided in several sections headed: introductory part providing the task of psychoneuroimmunolgy (PNI); the systems of […]

The Core Assessment topic that I chose was “Chocolate’s Effect on Women’s Sex Drive. ” I thought this to be an important topic since I am a man who is married to a woman who loves chocolate and that I have always heard that chocolate tends to curb a woman’s sex drive. In an effort […]

In the following essay I will be looking at both sides of the debate of whether neuroscience replaced psychology in explaining behavior. To begin with we must firstly understand what exactly neuroscience is and what it entails. It is generally defined as the study of how the nervous system develops, its structure and the functions […]

Introduction Neurons are the cells that receive and transmit electrical signals. The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a […]

Lab Report: Exercise 10: Organization of Nervous Tissue Purpose: The purpose of this exercise is to comprehend the organization and role of multipolar, unipolar, and bipolar neurons, as well as recognize nerve structures. There are no safety concerns related to this lab. Step 1: Relates to Lab Exercise 10/Activity 1, 3, and 4. Assignment 1: […]

Campbell’s AP Biology Notes Chapter 48: Nervous Systems Command and Control Center The human brain contains an estimated 100 billion nerve cells, or neurons Each neuron my communicate with thousands of other neurons Functional magnetic resonance imaging (fMRI) is a technology that can reconstruct a 3-D map of brain activity The results of brain imaging […]

Introduction This lab involves the examination of cutaneous receptors. There are four exercises. For this lab, report your observations in a formal report, according to the formatting prescribed in Lab Report Format. doc which is found on Blackboard under Assignments/Before You Begin. Equipment needed: Metal calipers or compass with pencil 2 or more blunt probes […]

A neuromuscular junction is a place in the body where the axons of motor nerves meet the muscle, thus transmitting messages from the brain which cause the muscle to contract and relax. Every organism has thousands of neuromuscular joints which are the locations and means by which the motor neuron of the nervous system that […]

At birth, a human child’s brain is not fully developed and requires neurological processes and environmental stimulation for development. Nevertheless, babies are born with all the neurons needed for information storage and transmission (Woolfolk, 2010, p. 29). The development of connectors, known as axons and dendrites, that allow information to travel across the brain is […]
