Abstract

Small, apparently redundant, muscles frequently act in parallel with vastly larger prime-movers and we call this morphological entity the “parallel muscle combination” (PMC). The small muscles of PMCs have much higher muscle spindle densities than their large counterparts, and we call the ratio of mean spindle density of the small muscle/s to that of the large muscle/s in a PMC, the PMC SPINDLE RATIO (PMC-SR). In view of this characteristic of PMCs we proposed that the small muscles thereof play a primarily proprioceptive role (Peck et al., 1984).
