Lab 2.1 - PrelabPhysioEx Ex. 3, Activities 1 and 3Before coming to class, complete PhysioEx: Exercise 3 (Nerve Impulses in Single Neurons) Activities 1 and 3. Note thatyou do not need to print or turn in your completed PhyisoEx activities. Instead, you should answer the questions belowand turn in these questions as your pre-lab for lab 2.1.Activity 1: Resting Membrane Potential (RMP).The axon membrane contains two kinds of Na* and K* channels. Leak channels are always open to allow a slight influx ofNa+ and larger efflux of K*. This helps generate the resting membrane potential (RMP). These simulations demonstratehow relative concentrations of Na* and K* inside and outside the neuron affect RMP as they diffuse down theirgradients. Follow the procedures in PhysioEx Ex. 3 Activity 1 and use your data from Chart 1 to answer the questionsbelow:1) What happens to the RMP as the extracellular K* is increased? In other words, does RMP become more positive,more negative, or does it stay the same?2) What generates the gradients for Na* and K* in a living cell?3) What could happen to neurons (and muscle cells) of someone that was injected with a high dose of KCI?4) If Na' channels were suddenly opened in a resting neuron, what would happen to the membrane potential?Skip Activity 2.Activity 3: Action Potentail Threshold1)Follow procedure in PhysioEx Ex. 3 Activity 3 and use your data from Chart 3 to answer the questions below:2)What was the threshold voltage to generate an action potential (AP)?3)Did the amplitude (height) of the AP change as the stimulus was increased?4)State the law or rule that describes this property:

We are answering question from 1 to 3. For rest of questions pls repost

ASSESSMENT EXERCISES: IDENTIFYING OBJECTIVE AND SUBJECTIVE DATA Scenario: Mr. Gutierrez, 34-year-old Hispanic man, was involved in a roll-over vehicle accident 1 day ago. In the accident, he sustained a crushing injury to his right hand. He has multiple superficial cuts from broken glass on his arms and face. This morning he describes his hand pain as throbbing and deep. He rates his pain as a 6 on a 0 to 10 scale. The dressing on his hand is intact with a small amount of dry, reddish-brown drainage observed in the palmar region. His fingertips are edematous and warm with a brisk capillary refill. His radial pulse is palpable and within normal limits. List abnormal subjective data from the case scenario above. List abnormal objective data from the case scenario above.
