Neurophysiology of Nerve Impulses. Physioex 3 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. - correct answer Increasing the extracellular K+ reduces the steepness of the concentration gradient and so less K+ diffuses out of the neuron. 2. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. - correct answer The membrane potential became less negative because l...

PhysioEx Activity 2 fully solved graded A+ 20231. Define the terms skeletal muscle fiber, motor unit, skeletal muscle twitch, electrical stimulus, and latent period - correct answer Skeletal muscle fibers: a long cylindrical cell with multiple oval nuclei just beneath its sarcolemma. Motor unit: consists of a motor neuron and all of the muscle cells it stimulates. Skeletal muscle twitch: a single stimulated contraction of whole skeletal muscle. Electrical stimulus: the elicitatin of ...
