      Primary Cortical Somatosensory Cortex

    • D.

      Brainstem / Thalamic

    Correct Answer
    A. Brachial Plexus
    Explanation
    The brachial plexus is the correct answer because it is a network of nerves that originates from the spinal cord in the neck region and supplies the upper limb with motor and sensory innervation. It is responsible for transmitting signals between the spinal cord and the arm, allowing for movement and sensation in the arm. The other options, such as the spinal cord, primary cortical somatosensory cortex, and brainstem/thalamic, are not directly involved in the innervation of the brachial plexus.

    • D.

      40-1kHz or -4dB

    Correct Answer
    A. 30-1kHz or -3dB
    Explanation
    This answer indicates that the MN/Ulnar Bandpass has a frequency range of 30-1kHz and an attenuation of -3dB. This means that the bandpass allows frequencies within the range of 30-1kHz to pass through with minimal loss, while attenuating frequencies outside of this range. The -3dB attenuation indicates that the signal power is reduced by half at the cutoff frequencies of the bandpass.

    Explanation
    The correct answer is N13-N20. This refers to the conduction peaks between the N13 and N20 waveforms. These peaks represent the electrical activity in the central nervous system during a specific time period. The N13 wave occurs first, followed by the N20 wave. This sequence of peaks is commonly observed in studies involving sensory or motor stimulation. The N13-N20 conduction peaks are important in assessing nerve conduction and can provide valuable information about the integrity of the central nervous system.

    Correct Answer
    A. EP-N13
    Explanation
    EP-N13 refers to the peak of the evoked potential waveform that occurs between the EP and N13 points. This waveform represents the electrical activity generated by the peripheral nerves and their conduction towards the brain. The EP-N13 peak is an important marker for assessing the integrity and efficiency of peripheral nerve conduction. It indicates the time it takes for the electrical signal to travel from the point of stimulation to the brain. Therefore, the correct answer in this context would be EP-N13.

    Explanation
    The correct answer is Nucleus Cuneatus & Fasciculus Cuneatus. The nucleus cuneatus and fasciculus cuneatus are both involved in the transmission of sensory information from the upper extremities to the brain. The nucleus cuneatus is located in the medulla oblongata and receives sensory input from the upper extremities via the fasciculus cuneatus. The fasciculus cuneatus is a bundle of nerve fibers that carries sensory information from the upper extremities to the nucleus cuneatus. Together, the nucleus cuneatus and fasciculus cuneatus play a crucial role in relaying sensory information from the upper extremities to the brain for processing.

    Correct Answer
    A. Nucleus Gracilis & Fasciculus Gracilis
    Explanation
    The correct answer is Nucleus Gracilis & Fasciculus Gracilis. The nucleus gracilis and fasciculus gracilis are both involved in the transmission of sensory information from the lower extremities to the brain. The nucleus gracilis is located in the medulla oblongata and receives sensory input from the lower extremities, while the fasciculus gracilis is a bundle of nerve fibers that carries this sensory information up the spinal cord to the brain. Therefore, the nucleus gracilis and fasciculus gracilis work together to relay sensory information from the lower extremities to the brain.

    Correct Answer
    A. C5-T1
    Explanation
    The correct answer is C5-T1. This is because the median nerve originates from the spinal cord segments C5-T1. It passes through the brachial plexus, which is formed by the nerve roots from these segments. The median nerve provides motor and sensory innervation to the muscles of the forearm and hand, as well as sensation to the palm and fingers. Therefore, C5-T1 is the correct answer for the origin of the median nerve.

      MCA

    • D.

      VBA

    Correct Answer
    A. Brachial Plexus
    Explanation
    The Brachial Plexus is the generator of E. The Brachial Plexus is a network of nerves that originates from the spinal cord in the neck region and extends into the arm. It is responsible for providing motor and sensory innervation to the upper extremity, including the muscles and skin of the arm. Therefore, it is the correct answer for the generator of E.

      C5s-EPc

    • D.

      EPc-EPi

    Correct Answer
    A. CPc-CPi
    Explanation
    The correct answer is CPc-CPi because it represents the difference between the central processing capacity (CPc) and the central processing input (CPi). This calculation helps to measure the efficiency or performance of the central processing unit (CPU) by comparing the amount of processing capacity available with the actual input being processed. By subtracting CPi from CPc, we can determine the utilization or effectiveness of the CPU in handling the given input.

      I

    Correct Answer
    A. G
    Explanation
    The given sequence CPi-EPc can be interpreted as a combination of two separate sequences: CPi and EPc. In the first sequence, the letters are moving forward in the alphabet by 1 position, so the next letter after C is D, and the next letter after P is Q. In the second sequence, the letters are moving backward in the alphabet by 1 position, so the next letter after E is D, and the next letter after P is O. Therefore, the next letter in the overall sequence would be the combination of the next letters in each sub-sequence, which is GD.
