Fig. 31.— Diagkam of the Main Paths of Nervous Impulses 

 FROM THE Body into the Brain. 



Three tpinal nerve fibres {F, II, III) are shown entering the cord. Each fibre divides 

 into three branches. 



Left : Impulses resulting from general sensation pass up in the cord as shown, entering 

 into and again emerging from the grey matter; theconnection is directly with the thalamus. 



Centre: The paths taken by impulses coming from the muscles and joints ; the con- 

 nection is with the thalamus, but indirectly through nuclei in the medulla. 



liigJit : The paths taken by impulses coming from the muscles and joints, and entering 

 in the cerebellum, but also ascending to the cortex via the.thalamus and returning to the 

 cord via the red nucleus.
