The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

MOTIVATION Concept of Motivation: Motivation is a psychological concept which acts as a force that propels a person to act or not to act in a certain way. Robert D. Irwin defines motivation as “Motivation means a process of stimulating people to action to accomplish a desired goal”. A manager needs to coordinate several factors of production and these factors can be classified into non human and human factors. The efficiency of non human factors such as material‚ machine‚ etc depends on the technology

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

Using Rewards to motivate employees MOTIVATION Some individuals are driven to succeed. A students who struggles to read a textbook for more than 20 minutes may devour Two States in a day. This document tries to put perspective into the reasons behind these varying degrees of motivation. Remember than the levels of motivation varies both between individuals and within individuals at different times. There are three key elements that define motivation‚ namely‚ Intensity‚ Direction and Persistence
