| Outline of Final Research Achievements |
This study was performed to investigate how the palatine aponeurosis, medial pterygoid process (MPP) of the sphenoid bone, and tensor veli palatini (TVP) muscle form the pulley: muscle-tendon-bone complex.At E14 and 14.5, ALP showed a reaction throughout the MPP. The col II-positive area expanded until E16.5, but it was markedly reduced at E17. The TVP initially contacted with the palatine aponeurosis at E16.5. The major axis and width of the MPP and the number of TRAP-positive osteoclasts were significantly increased as the TVP and palatine aponeurosis joined.Therefore, in addition to the tissue units: muscle, tendon, and bone, the interaction in organogenesis promotes rapid growth of the pulley: muscle-tendon-bone complex.
