Experiment AN-3: Neuromuscular Studies
Introduction
The brain uses specialized nerves to control the movements of the voluntary muscles. On the other hand, the neuromuscular system refers to the combination of the muscles and the nervous system, working together in order to allow movement. The present study, which investigates the neuromuscular junction, aims at demonstrating some electrical properties of the moral neurons and the muscle. The muscle and nerve action properties were recorded from the nerve-muscle preparation. The investigator determined the synaptic delay and the conduction time of the neuromuscular unit. In addition, the effects of a particular chemical agent and the stimulus frequency …show more content…
Impacts of Curare on the muscle CAP In Figures 2 and 1, the effect of the drug Curare on the muscle CAP commences when the amplitude is adjusted at 0.4 volts and increases linearly with the increase in the stimulus amplitude. In the normal treatment, however, an increase in the 0.4 stimulus voltage raises the amplitude but decreases the period. Figures 3 and 4 show that the period and amplitude of the muscle CAP had low values under the Curare treatment. Therefore, the drug reduces the amplitude and period of the muscle CAP. The effect is attributed to the inhibition of acetylcholine receptor by Curare.
Analysis of Variance
A one-way ANOVA was performed on the amplitude factor (Table 1). The statistical theories for the ANOVA …show more content…
For example, the compound physostigmine causes the inhibition of the enzyme acetylcholinesterase. The inhibition prevents acetylcholine degradation and causes contracted paralysis. The second importance is that the neuromuscular junction in frogs is an example of the general synaptic function. Therefore, studying the model increases the understanding of the processes that occur in a synapse. Thirdly, the results of the experiment explain some of the electrical features of neurons and muscles.
Conclusion
The neuromuscular system is vital for the movements conducted by the voluntary muscles. The system is responsible for the transmission of action potentials to the muscle fibers. The neuromuscular junction is where the nerve impulses are transmitted to the muscles. The electrical signals travel from the brain and move down the nerves where they prompt the release of acetylcholine from presynaptic terminals. The stimulation of the receptors by the acetylcholine causes the muscles to contract. As a result, the neuromuscular junction is critical in the communication that occurs between the neural and the muscular system.
