Relationships between Group Ia afferent fibres and motoneurones
In Chapter 11 the afferent fibres from the primary endings in muscle spindles (Group Ia axons) were discussed. It was shown that each Ia afferent fibre, near its entrance into the spinal cord, gives off collaterals at an average frequency of one every millimetre. The collaterals have three main areas of termination in the lumbosacral cord: in lamina VI, in lamina VII (to the region containing the Ia inhibitory interneurones) and in lamina IX (the motor nuclei).
