"Adversity has the effect of eliciting talents in prosperous circumstances would have lain dormant." What Horus described in this quote‚ meant that when hardships or impossible tasks face a person‚ and if that person has the courage and will to achieve them‚ the man will uncloak his true strengths. No one could disagree with this‚ including me. Believing in our own skills and believing that anything can be achievable‚ creates a way for us to prove others wrong and prove yourself right. Millions

The Nervous System: Ion Channels 1. What structures in the cell membrane function as ion channels? Intergral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? a. Charge on ion (+ or -) b.Size c. The amount of water the Ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an non-gated channel. 4. Would

neuron carries important information through action potential‚ this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons

Affirmative action has been used throughout history to decide whether or not "minority" status American citizens should have a voice. Affirmative action refers to an action or policy favoring those who tend to suffer from discrimination in relation to employment‚ education etc. This topic has been very controversial in both the past and present. It has been commonly used in the college acceptance process in order to include different cultures and ethnicity’s into schools. This process should be used

The Action Potential An action potential‚ also called a spike‚ nerve impulse‚ and discharge‚ is the rapid reversal of charge of the cell membrane. These changes in charge occur within milliseconds‚ meaning the action potential travels very quickly down the axon in order to convey information over long distances. This transfer of information occurs within six phases and requires the presence of multiple pumps and channels embedded in the membrane to control ion concentration. Phase 1: The Resting

POTENTIAL EFFECTS OF DISCRIMINATION. TASK 3: In looking at this task‚ we have already studied the first part of the topic at the beginning of the Unit. Forms of Discriminatory Practice exist‚ in the form of: Prejudice‚ Stereotyping‚ Labelling‚ Bullying‚ Abuse‚ Lack of choice‚ Infringement of Rights‚ and Covert/Overt abuse of Power. Do we accept that these forms of discrimination exist? What do you think……as maybe you do not agree? Discrimination can be understood as damaging the individual

Task 3 P3 - The potential effects of discrimination There are lots of potential effects related to discrimination. It includes things like disempowerment‚ low self-esteem and self-identity and also marginalisation. I am now going to explain these effects and connect them with a case study. Disempowerment is when a person or group of people may be made to feel less powerful or confident. Some people may try to fight against the discrimination causing an argument but many people do not and they lose

fundamental unit of the nervous system. These neurons work together with other excitable cells to produce action potentials when they receive electrical or chemical stimuli. Action potentials can be thought of as an “all-or-nothing” event and occur as a large-scale depolarization when sodium and other positive ions rapidly enter the neuron through membrane channel proteins. Once initiated‚ action potentials travel down the length of the axon and when it reaches the end a neurotransmitter is released into

the spinal cord that control the muscles * Vertebrate brain divided into three parts * Hindbrain - most ancient part and regulates motor activity below the level of consciousness * Midbrain - optic lobes are part of the midbrain and was a center for coordinating reflexes involving the eyes and ears * Forebrain - originally dealt mainly with smell. Later‚ the thalamus evolved to receive sensory input from the midbrain and the hindbrain and to pass it on to cerebrum * Cerebrum
