BIO 252 LABORATORY REPORT Activity 3: Recruitment and Contractions Name: Instructor: Date: PREDICTIONS 1. When the arm goes from resting to flexing, the amplitude and frequency of sEMG spikes will: increase 2. During flexion, the amplitude and frequency of sEMG spikes will _be more_ during extension. 3. Recruitment of motor units will be greatest when the load is: 20 MATERIALS AND METHODS Comparison of motor unit activation during muscle tone and concentric and ecc...

2024 CNIM Muscle Anatomy Latest Questions With Complete Grade A Answers 1. Electromyography (EMG) Answer: -A record of electrical activity of a muscle. -Subdermal needle electrodes into skin over muscle. -Can be rendered unhelpful by neuromuscular blockade. -Includes spontaneous EMGs and triggered EMGs. 2. Innervation Answer: -Irritation of nerve roots in surgery result in depolarization in nerve,resulting in contraction of innervated muscles. -Targets muscles that will show activ...

When should you use SSEPs? - Answer- Use SSEP's for every case Where do you stimulate for UE SSEPs? - Answer- Ulnar Nerve - any surgery below the C4 level Median Nerve - any surgery above the C4 level Where do you stimulate for LE SSEPs? - Answer- Posterior Tibial Nerve at the ankle Pop Fossa - if severely diabetic or hypertensive Peroneal - if the patient is amputated below the knee N20 - Answer- N20 - Contralateral (to stimulation) post central gyrus.
