Spinal Chord Neurons MCQ

  1. Aug 5, 2011 #1
    1. The problem statement, all variables and given/known data
    [PLAIN]http://dl.dropbox.com/u/26176167/Screen%20shot%202011-08-05%20at%2012.50.55.png [Broken]

    Find the 1 incorrect option.
    2. Relevant equations

    3. The attempt at a solution
    Well, I'm trying to narrow it down. I know that the spinal cord contains many interneurons/local neurons, so C is correct.
    I'm not sure where the Soma of afferent and efferent neurons are located. Maybe afferent nuclei are located outside of the spinal chord?
    I know that the intrafusal fibres in the muscle spindles are supplied by gamma motor neurons, which are controlled by descending neurons from brain. So D is correct?
