Question
Chapter 15, Problem 11CP
Summary Introduction
To determine:
The anatomical basis for the fact that the left side of the brain controls motor function on the right side of the body.
Introduction:
There are two types of motor neurons: upper motor neuron and lower motor neuron. The cell body of upper motor neuron lies in the CNS processing centre and the cell body of lower motor neuron lies in the nucleus of brainstem.
