Title: Describe your four tracings and explain what has happened in each of them. Post by: sunshine on Feb 27, 2011 I am stuck on just a few questions and wondered if anyone could help me out.
Activity 3 question: An individual muscle fiber follows the all-or-none principle—it will either contract 100% or not at all. Does the muscle we are working with exhibit the all-or-none principle? Why or why not? Activity 9 question: Describe your four tracings and explain what has happened in each of them. My first three tracings are flat and the fourth has a slight rise and fall but I am stuck as to why this is happening to each :'( Thank you in advace for your help |
