Topic: What does EMG activity look like and how does this change with increasing intensity of muscle contraction? What does the relationship between the biceps RMS EMG amplitude and contraction intensity suggest? If contraction of one skeletal muscle fibre produces electrical activity (i.e. EMG activity), what does the above relation imply? There are several factors that influence tension produced by a whole skeletal muscle. Which 2 factors are preliminary influencing the relationship between the Biceps RMS EMGamplitude and contraction intensity in the current task? Topic 2: How do muscle work together to perform coordinated movements? Describe the EMG activity in the triceps muscle during elbow flexion and what this activity represents. What might the purpose of this be? Topic 3: What is a stretch reflex? Stimulus that will evoke the reflex is a light tap on the patellar ligament. How will the light tap affect the length of the rectus femoris muscle? What effect would the volunteer’s height have on the latency of tendon hammer reflex? Botulinum toxin is a neurotoxin that is produced by the bacterium Clostridium. Botulinum toxin prevents the release of acetylcholine (ACh) from alpha motor neurons at the neuromuscular junction. This neurotoxin is marketed commercially under the brand name Botox and is used for medical and cosmeticl purpose. What would happen to the amplitude (size) of the quadriceps stretch reflex response if Botox was injected into the quadriceps muscle? Which somatosensory pathway/s transmit information from muscle spindles to the brain, and why does the brain interpret activation of muscle spindles in flexor muscles of the forearm to mean that the wrist and/or fingers have undergone an extension movement? I found I am struggling with answering some specific part of topics. Before the real exam begins, I would really appreciate seeing how these questions could be answered in a detailed and well structured way. I’m aiming to improve my performance and understand exactly hat a strong, high-level response should look lie. I’d like to see how an expert would approach them.
