- MovementKnow the components of the motor control system What are the components of the motor control system? Intro to neuroscience College-level Please provide some pictures and visual explanations to these concepts. I need a visual answer and not just an essay. So, the explanation must include diagrams of the relevant component of the motor control system.Neuroscience: Define end plate potentials and describe how their propagation leads to a musclecontraction Please provide pictures with your explanation. This should help me prepare for an upcoming exam. I need to understand what is going and I'm a visual person!!1. Make a model or draw 3 multipolar neurons. Imagine you had something crawling on your arm. The first is a sensory neuron, getting its information from the skin and sensing the movement. The second is an interneuron. It relays information from the first (sensory neuron) to the CNS. The third is a motor neuron. It begins in the CNS but leads all the way to the muscle, so that you can move the fingers and scratch the area. On your images/model the "dendrites" should be blue, "axon" should be green and "soma" should be yellow. As you connect them to each other, take notice in which areas are the receiving end, and which are the transmissive ends.
- Co-activation of α and γ-motor neurons :-a- increases γ-motor neuron discharge whenever the activity of α-motor neurons rises to a high levelb- is mediated by interneurons that link the α and γ-motor neuronsc- maintains the proprioceptive information to higher centers during muscle contractiond- increases the α-motor neuron discharge whenever the activity of γ-motor neurons rises to a high levelThe following were extracellular recordings obtained from the giant nerve fibers of an earthworm after delivery of a depolarizing stimulus at the time indicated. Which of the following letters corresponds with the fiber that had the fastest action potential conduction velocity? I OA 0.05 0 -0.05 -0.1. + Action Potential 0.024 B W 0.002 0.004 stimulus delivered A OB OC None of the above are correct; all had the same conduction velocity 0.006 C 0.008 0.01Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.

- Neuroscience Question: Which of the following statements ACCURATELY describe spinal cord organization. α-motor neurons are organized from lateral to media such that those found towards the medial section of the spinal cord controls the distal muscles. Lumbar spinal cord enlargement is observed where neurons that innervate the legs and feet are located Neuronal cell bodies (somas) of neurons that innervate single muscles are only found in a single spinal cord segment. Muscles of the trunk are represented medially while muscles of arms and hands are represented laterally Group of answer choices 1, 2, 4 2, 3, 4 2, 4 4 only 1,2,3,4 Here is my reasoning: Please you be the judge if this is correct! α-motor neurons are organized from lateral to medial such that those found towards the medial section of the spinal cord control the distal muscles. This is inaccurate. α-motor neurons are organized from medial to lateral in the spinal cord, with those medially controlling axial…_____ neurons carry impulses from the muscle to the CNS, while _____ neurons complete the loop by carrying impulses from the CNS to the muscle. Group of answer choices Sensory, motor Flexion, extension Input, output Synchronous, asynchronousA neuron of the median giant fiber of an earthworm would respond to an increased intensity of a stimulus by: Increasing the amplitude of action potentials generated Increasing its resting membrane potential Increasing the frequency of action potentials generated Increasing the conduction velocity of action potentials generated
