Laboratory Report - Essay ExampleQuestion 4 In this example of the cubital joint flexion unloading response (i.e. the task performed during the laboratory), state the muscle from which the data from sheet 1 was recorded, and whether the weight was removed unexpectedly or was self-removed by the subject. What was the response time of the responseAnswer The data from sheet 1 showed the elbow flexion unloading response of the biceps. The weight was self- removed as we observed the reduced electromyogram activity of the biceps, starting onwards the onset of the unloading. The latency time is about 50 milliseconds.Question 5 Based on evidence from the laboratory and/or the literature, explain the major reflex pathway that causes the reduction in agonist EMG in the unexpected unloading response. Include the series of neural events from reasonable prior to the release of the weight until the end of the first agonist (biceps) response.Answer Anticipation in the postural domain is an exam ple of the ability of the CNS to call off the consequence of the mechanical effect of movement on posture and helps minimize a forthcoming disturbance. A classical example was provided by the pioneer produce of Belenkiy et al. (1967). They showed that, during arm raising while standing, the prime mover activity in the biceps brachii was preceded by an activation of a leg muscle, the biceps femoris, starting 100 ms before the movement onset.
