Eliciting a Nerve Impulse Activity 1: Electrical Stimulation 1. Do you see any kind of response on the oscilloscope screen? Just a flat line. 2. What was the threshold voltage‚ or the voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold

Final Research Paper OL-500 Human Behavior in Organization Kesha Jaramillo Southern New Hampshire University Abstract This paper will discuss Malden Mills and the decision that CEO Aaron Feuerstein’s actions following the 1995 fire. The organization is associated with both business and basic human values which makes it a brand with which anyone can relate. After the factory burned down in a fire in 1995‚ Aaron Feuerstein chose to value his employees over what could have been a huge monetary gain

Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens

Activity 1 1. Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Therefore‚ the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. 2. Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. My results went well compared to my prediction

Task 1 Research the stages of development a child/young person may pass through within the age ranges: 0-3 years 3-5 years 5-8 years 8-12 years 13-19 years. Physical Development Babies all grow at different rates but in the same order. One 12 month old may be walking unaided‚ another may not even be sitting up alone. Several different factors can influence physical development‚ such as nutrition‚ genetics‚ culture‚ body build and birth size. Achievements that children reach in development

A creed is a set of words. It says what a person or group believes in‚ and helps express the identity of the group. It is a faith put into words. Throughout its long history‚ the Catholic Church has pursued a deeper understanding of Jesus and his message. Driven by the human need to name

Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.4 2. At 40 seconds‚ pH = 7.4 3. At 60 seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? No‚ it stayed at 7.4 5. Was the pH level always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No‚ it stayed at 40mm Hg Activity 2a: Hyperventilation – Run 1

Respiratory System Mechanics Simulation Lab Activity 1: MRV __7500__ ml/min =500 tv x 15bmp Does expiratory reserve volume include tidal volume? Explain. Expiratory reserve volume (ERV) does not include tidal volume. Expiratory reserve volume is the amount of air that can be expelled after a normal tidal exhalation. This means that tidal volume is not included in the ERV measurement. Activity 2: FEV1‚ as % of VC Radius FEV1 Vital Capacity FEV1% 5.00 3541 4791 73.90 4.50

Electrical Stimulation Activity 1: Direct Heart Stimulation 1. Did you see any change in the trace? No change in the trace 2. Why or why not? This is because it needs more simulation 3. Did you see any change in the trace? I did see a change in the trace 4. Why or why not? There is double stimulation 5. Describe the change you see in the trace. How does it differ from the baseline trace? The trace increased from the baseline trace 6. What effect do the repeated stimuli
