Learning Objectives. To understand what factors affect the speed of conductance of an action potential.. To understand what the ‘refractory period’ is.. To understand what the role of the refractory period is in separating one impulse from the next.. Learning Objectives. To understand how an action potential is propagated along an axon.. To understand the difference between the propagation of action potentials in . myelinated . and . unmyelinated. 6.5 Nerves, Hormones, and Homeostasis.

Action Potential. ~1900 Julius Berstein suggested that nerve impulses were an electrochemical message created by the movement of ions through the nerve cell membrane.. Several tests have been proposed for assessing the need for nonlinear modeling in . time series analysis. Some of these tests, such as those studied by Keenan (1985. ). Keenan’s test is motivated by . BACKGROUND. Tumor necrosis factor (TNF) is an effector cytokine involved in numerous pathologies and inflammatory responses [1].
