WebA molecular oscillator, known as the somitogenesis clock (Palmeirim et al., 1997), regulates the periodicity with which somites form, and a well accepted, though not directly measured, explanation for the observed patterns is that the clock oscillation rate attains its maximum value in the posterior PSM and decreases anteriorly along the AP axis. WebSomite formation is an autonomous process and that, at this time, no extracellular signal specifying antero-posterior position or timing is involved. What is the clock and wavefront model of somite formation? Clock and wavefront model proposed to account for the observed periodic and spatially organized appearance of the somites. pehl et al 1997 j. physiol 498.2 483-95WebFIGURE 5.2 The clock and wavefront mechanism of somitogenesis.
