Morphometric analysis of the human cervical motoneurons in the aging process.
We examined 12 human cervical spinal cords to study the numbers and transverse cell body areas of the motoneurons in relation to the aging process. Our conclusion was that cervical motoneurons regulate their function by increasing in size to compensate the loss in numbers that occur as people get older.
