Physiology Article Notes
I thought some of the subheadings for the article did not make very much sense. It went from history to women in physiology to sub-disciplines and then finally to human physiology. I think the women in physiology subheading should have been at the end and they also should have included potentially men in physiology as well. I think that these subheadings made the article confusing. I thought the history section was well written, I think there might have been some close paraphrasing in this section when describing the history and specifically the people who made breakthroughs at the end of the section. The lack of citation in the human physiology section makes me question its credibility as well as I wonder if it was copy and pasted in.

Tetanic Contraction Article
I thought I would write about how to observe these types of contractions because that had not been talked about in the article and I think it could be interesting knowledge. I also thought I would write about where these types of contractions can occur like in cardiac muscles and other areas of the body not just the typical muscles we think of when we think about this. I also would further define a twitch, summation, rough and smooth tetanus. Some sources I would use are:

Adding to Article
A tetanic contraction can be either unfused (incomplete) or fused (complete). An unfused tetanus is when the muscle fibers do not completely relax before the next stimulus because they are being stimulated at a fast rate; however there is a partial relaxation of the muscle fibers between the twitches. Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. A fused tetanic contraction is the strongest single-unit twitch in contraction.
