Excitation contraction coupling process essay

Suppose further that the Japanese government convinces your largest importer the US, say to strengthen its currency to avert a further Japanese economic disaster, and that the prices of your export goods become relatively unattractive because your currency is pegged to the dollar. Your exports weaken, currency speculators see an opportunity to sell you short and bet against your currency until it cracks, your stock market crashes and you start defaulting on loans to your biggest creditor Japan, whose banking system was already insolvent anyway.

Completely different meanings even occur in different branches of physiology, e. As a student, it is easy to despair! But the meanings of words are very precise in science: This glossary is for browsing in, testing yourself, and learning about words that catch your eye.

Stop and read wherever you may have doubts or interest. Also of course it is a place to look up words you come across and don't understand.

But it is very selective. You need both an English dictionary and a scientific or medical dictionary too. Many words that you think you understand OK, you may find aren't used quite how you thought!

This glossary concentrates on words that often cause confusion, especially in the basic sciences physics, chemistry and mathematics that are the foundation of physiology. You don't need to understand everything, but the more you understand, the easier it will be to learn more.

You are often expected in exams to explain the meanings of words: Click or email to a. It is usually simpler and clearer to say 'horizontal axis', since most people have to stop to think which axis 'abscissa' means.

As an aid to memory: Note that all parts of a rotating object are accelerating except on the axiseven if the rotation is steady: Acceleration is detected in man largely by the labyrinths.

Acclimation is sometimes used specifically to mean adaptation to a single changed factor as under laboratory conditions. Used in several senses: Attenuation or absence of a response when a stimulus is applied slowly e. NB this is distinct from adaptation, but is often seen in the same systems.

Adjustment of focus of the eye. Cumulative toxins are ones that are absorbed but not excreted, for which it is the total dose over a prolonged period that matters rather than the level of exposure at any one time. Accuracy is limited firstly by the ability of a measuring system to distinguish different conditions resolution and secondly by its ability to relate the conditions correctly to a standard calibration.

The two considerations must not be confused. A high resolution instrument giving stable readings and sensitive to small changes may nevertheless be completely inaccurate if not adequately calibrated.

Accuracy cannot usually be greater than the resolution of a measurement, except in special circumstances e. An acidotic condition may be capable of being restored to normal acid-base balance by increasing respiratory ventilation to reduce the CO2 content of the body respiratory acidosisor it may require retention or injection of HCO3- metabolic acidosis.

Disturbances are lessened in the short term by numerous pH buffer systems. Influences affecting blood pH are altered absorption, metabolism and respiration, and disturbances affecting the control systems.

Action potentials occur spontaneously or as all-or-none or frequency coded reactions to stimulation. Sodium spikes are brief ca. A compound action potential is an extracellular recording of the combined effect of action potentials in many cells.

A catalyst reduces the activation energy. This requires energy, and can occur by linkage of carrier mediated transport to a process providing energy, such as the hydrolysis of ATP or the downhill movement of another substance.

The state of doing something: In chemistry a parameter similar to concentration, that determines the rate at which reactions take place. The ratio of activity to concentration is the 'activity coefficient', usually less than 1 because of molecular interactions in the solution that interfere with reactions.

Visual acuity depends on light level, and is highest at the fovea.Start studying Describe, in detail, the process of excitation-contraction coupling, beginning with the arrival of an action potential at the axon terminal (how we tell our muscle to contract)..

These linked events are referred to as excitation-contraction coupling. The excitation process begins when the acetylcholine (ACh) is released by a motor neuron at the neuromuscular junction. Acetylcholine (ACh) release.
