Name: _________________________________ EXERCISE 3 Neurophysiology of Nerve Impulses Laboratory Report Answer the following questions. (3 points each). 1. What is the difference between membrane irritability and membrane conductivity? Membrane irritability is the ability to respond to a stimuli and convert it in to nerve impulses. Membrane conductivity is the ability to transmit that impulse that is created by membrane irritability. 2. If you were to spend a lot of time

LE IN The article is organized as follows. We begin by reviewing the reference literature before introducing the concept and practice of dynamic sector rotation. We then present our experiment: to apply a number of heuristic techniques of sector momentum to a fully invested portfolio of sector-specific investments (41 funds of the Fidelity Select Sector family‚ for which we have data). We first present the empirical results obtained using alternative measures of relative strength (rate of change

CONSERVATION OF MOMENTUM PRACTICAL WRITE UP AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was

EXERCISE 3: Neurophysiology of Nerve Impulses ACTIVITY 1: The Resting Membrane Potential Answers 1. The nervous system contains two general types of cells: neuroglia cells and a. nerves. b. cell bodies. c. neurons. d. nephrons. 2. The resting membrane potential of the neuron in this lab under the control conditions was _______ mV. 3. True or False: For most neurons‚ the concentration of Na+ and K+ ions inside and outside the cell are the primary factors that determine the resting membrane

Maya Angelou was born on April 4‚ 1928‚ in St. Louis‚ Missouri‚ and she was a writer and civil rights activist known for her 1969 memoir‚ I Know Why the Caged Bird. For Maya‚ her poem made literary history as the first nonfiction best-seller by an African-American woman. The poignant work also made Angelou an international star.In 1971‚ Angelou published the Pulitzer Prize-nominated poetry collection Just Give Me a Cool Drink of Water Fore I Die. She later wrote the poem "On the Pulse of Morning"—one

History 020 Rachel Chow 1 January 2011 A REVIEW OF JAMES K. POLK AND THE EXPANSIONIST IMPULSE James Knox Polk‚ a candidate of the Democratic Party in 1844‚ became the US president between 1845 and1849; however‚ he remains largely forgotten today‚ in the popular US imagination‚ because memories concerning his presidency had been overcome by memories of the most famous presidents like Abraham Lincoln. Remembrance of Polk as the 11th
