Frequency Of Muscle Mastication
In this lab we were attempting to find the different frequencies that are caused by doing different things with your jaw. Such as, clenching your jaw, or eating a carrot. We tested the different frequencies using a Vernier EKG Sensor. This showed us the electrical activity being generated by the movements of the jaw.
The specific purpose of this experiment, is to examine the electrical activity generated by chewing and see how food texture influences the strength of contraction in the masseter muscle of the jaw. We will be using the masseter muscle function while performing different types of chewing activities, such as, chewing gum, eating a carrot, and eating a hard-boiled egg.
The materials used in this lab was a LabQuest and a LabQuest App, to be able to record all the data. A Vernier EKG Sensor and electrode tabs to be able to view a graphical representation of the information. Chewing gum, raw carrot, and a hard-boiled egg to view the experiment in different forms or trials. And soap or rubbing alcohol to clean the places where the electrode tabs are to be placed.
The results that were found by doing this experiment were, that by chewing gum the amplitude of the electromyogram, or EMG, electrical activity was slightly greater than the carrot or egg. The carrot had an amplitude of EMG electrical activity that fell in between the chewing gum and the egg. And the hard-boiled egg had an amplitude of EMG electrical activity that was less than both of the chewing gum and the raw carrot.
At the end, even though there was not a very significant different between the amplitudes of the different things used. The chewing gum still ended up having the highest amplitude of electrical activity produced than the other two things. The compared rates of chewing within the lab group/class were pretty close with no significant difference. This experiment helps people understand that if someone has a temporomandibular disorder...
