The Human Nervous Sysyem

The nervous system is one of the major systems in the human body.  It allows the proper coordination of the sensory and motor neurons with the actions or behavior of an individual.  The nervous system of the human body is divided into the peripheral nervous system, which is comprised of motor and sensory neurons that… View Article

Response of the Organism: Hyalella azteca

Chemosensory organs in many crustaceans including Hyalella azteca allow them to locate food and mates while entirely avoiding predators. When detecting environmental changes such as the change in chemicals such as salinity, many amphipods have tiny hair-like organs containing sensory cells called sensilla (Hallberg, 2011). These chemosensory olfactory receptors are virtually found on many parts… View Article

Comparison – Graded Potentials to Action Potentials

A graded potential in physiology, is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential, an action potential is described as brief, rapid, large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the… View Article

Effect of Toluene and Xylene in solvents on humans

Toluene and Xylene are some of the major compounds in the solvents that affect the humans. Both, Toluene and Xylene, exert some effects like irritation at the site of contact and CNS depression. Irritation Solvents are in liquid form when at room temperature, but they are volatile too. When these solvents are in liquid form,… View Article

Chiropractic Work: The Safe Choice

“Get knowledge of the spine, for this is the requisite for many diseases.” –Hippocrates, 460-377 BC. If a Greek physician could make this statement over 2300 years ago, why is it such an under-exposed theory today? As stated in Chiropractic First, written by Dr. Rondberg, a chiropractor of 35 years and founder of the “Chiropractic… View Article

Neurotransmitters on Physical and Mental Behavior

Our physical and mental behavior is controlled by what is called Neurotransmitters. These neurotransmitters are described as free floating chemicals in our brain transmit signals in the synapse, a junction that permits a neuron to pass electrical signals to other cells. In this paper I will identify four major neurotransmitters, such as the dopamine, acetylcholine,… View Article

Cranial Nerves

The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions, such as the ability to speak, and see amongst us. This brain is made up of simple mater (Pia mater, Arachnoid mater, Dura… View Article

Measurement of Compound Action Potentials from the Frog Sciatic Nerve

Abstract: The purpose of this experiment was to examine how the compound action potentials propagate down the sciatic nerve of a frog based on varying stimuli. Before the nerve could be tested it needed to be extracted from the thigh of the frog and then submerged in saline. Several varying stimuli were used and recorded… View Article

Neurofibromatosis Case

Effects / Symptoms Neurofibromatosis causes a deficiency targeting the nervous system as part of a genetic disorder. The two most common types are abbreviated into NF1 and NF2. NF1 is characterized by café au lait spots, or patches of tan and light brown skin. Another characteristic would be neurofibromas, which are soft, fleshy growths that… View Article

The Biological Approach

One of the most perplexing issues in psychology is understanding the relationship between the mind and the brain. We all recognize that we have conscious awareness of our surroundings, and also of ourselves (self-awareness). It is this experience which has normally been described as the mind. But what is the basis of the mind? Is… View Article

Drug Interactions on Synapse

Homework on Drug Mechanisms 1. Release and degradation of the neurotransmitter inside the axon terminal. Drug: Reserpine Pharmacology: Most often used to treat mild to moderate hypertension. Mode of action: Reserpine inhibits the ATP/MG2+ pump responsible for packaging neurotransmitters into vesicles in the presynaptic neuron. This causes the free neurotransmitters to be degraded by MAO,… View Article

Optogenetics Specific Aims

Muscle disorders of the masticatory systems, or neuromuscular dysfunction, has two major symptoms: pain and dysfunction. Millions of people are impacted by muscle fatigue, muscle tightness, myalgia, spasms, headaches, and decrease range of motion each year because of this disorder [1]. Over the years, scientists have used many treatments to try to cure these muscle… View Article

Antidepressant Case Study

The debate over antidepressants has waged on for over more than half a century. Two heads of the Department of Psychiatry in Washington University discovered that depression was just as much biological as it was physiological meaning that people with depression had an abnormal chemical make-up in the brain. This discovery increased the demand for… View Article

Bipolar Case Study

I. INTRODUCTION A client diagnosed with Bipolar I disorder, such as Mary Ann Garces, intrigues and challenged the student nurses to applying onto the practical field, their acquired knowledge, attitude and skills from preceding lessons in order to function as an operative and effective member of the multidisciplinary team. The group members are determined to… View Article

Discuss the Biological Approach in Psychology

Discuss the biological approach in psychology. Refer to at least one other approach in your answer. (12 marks) The biological approach focuses on both the physiological and evolutionary aspects which explain human behaviour. The causal level of analysis incorporates physiological explanations, such as the effect of nerves and hormones on behaviour. According to biological psychologists,… View Article
