Summary Introduction
To review:
The reasons behind motion sickness faced by many people after a roller coaster ride or even riding a car or a boat. However, the gymnasts not do get motion sickness while performing.
Introduction:
Motion sickness is the feeling of disagreement between the visually and vestibule system perceived movement. The brain receives mix signals by eyes and ears. This makes a person develop some symptoms of motion sickness. The symptoms of motion sickness are uneasiness, cold sweats, and dizziness. Some people even experience pale skin, increased production of saliva followed by a headache and fatigue.

What generally happens when a perturbation is introduced during a series of movements?
The brain adapts to the perturbation by recalibrating the internal model until error is reduced.
The brain perceives the perturbation but does not adapt.
The brain instantly responds to the perturbation by reducing the error to zero.
The brain ignores the perturbation until it is removed.
You are at the gym and doing strength training. You feel in good shape and should try to break personal records in squats. You place the bar on your back and begin to take in, that is, your motor neurons begin to send action potentials through all your motor units to the thigh muscles.
What is the contraction called when you a) bend down and b) are in good shape and can generate more force than the bar weighs c) stay standing in one and the same position without being able to push yourself up in a standing position?
Adequate level of muscle tone is essential for the accurate performance of voluntary movements, because :-a- it adjusts the α -motor neuron discharge initiating voluntary movementsb- it adjusts posture of proximal joints of the acting limbsc- it adjusts the upright posture of the whole body during voluntary movementsd- it adjusts sensitivity of the spindles of the involved muscles

- You decide to do a series of experiments to determine where the toxin has its effect. You accomplish this by using a good, old- fashioned sciatic nerve/gastrocnemius preparation from a frog leg. This preparation dissects out the sciatic nerve (which contains the alpha-motor neuron fibers) still connected to the gastrocnemius (calf) muscle as shown below. The prep is placed in artificial ECF. Muscle Nerve Femur When you stimulate the nerve electrically, the muscle contracts. When you directly stimulate the muscle electrically, it also contracts. You then add the curare to the artificial ECF. Now, when you stimulate the nerve, the muscle no longer contracts. However, when you stimulate the muscle directly, it does contract. Based solely on these data, this means curare is potentially acting on: O Either the alpha motor neurons' ability to conduct action potentials, or the muscle's ability to conduct action potentials, but not on the neuromuscular junction. O Either the alpha motor…arrow_forwardAfter sprinting 100 meters 1) Identify the specific disturbance(s).

He has noticed some arm and hand shaking in the past year, but assumed it must be related to low or high blood sugar levels because he has had some issues with that in the past. However, the shaking/twitching has become more consistent lately and does not seem to be correlated with his diet. Russell’s doctor said that the stress of his job could be the problem, so he took the entire summer off from teaching.When he returned to work in the fall, Russell and his students noticed that his handwriting has become nearly illegible. Drinking a cup of coffee without spilling had also become a challenge. Russell returned to his doctor, who performed a physical exam and a few tests. Here are the notable results: shuffling gait, mild bradykinesia, mild voice tremor, intermittent rigidity of the limbs, and normal EEG.Which of Russell’s physical exam findings could be related to a brain condition?arrow_forwardRussell is 72 years old and is still working part-time as a professor.
