Fig. i. — Diagram to illustrate afferent kinesthetic system conveying impulses from tactile 

 corpuscles, from muscle and tendon by way of the sensory nerves to the spinal cord, and 

 thence to the cerebrum and cerebellum. 



The efferent motor projection systems from the cortex cerebri and the cerebellum are shown terminating at 

 the spinal motor efferent neurones, which transmit impulses by the motor nerves to the muscles. The 

 numerous pyramidal cells of the cortex represent the association system of neurones which link up all 

 the perceptor centres with the sensori-motor region.
