| Research Abstract |
Some studies have discussed that the nervous system contributes to bone metabolism. However, the neuroanatomical basis for bone metabolism is not clear especially in craniofacial bones. I have investigated the innervations of craniofacial bones by means of immunohistochemistry. Distribution patterns of the peripheral nerve were detected using antibody against vesicular glutamate transporter (VGluT). The VGluT positive nerve (VGluT+) releases glutamate as neurotransmitter. I found the VGluT+ terminals in the periosteum. The osteoclast and osteoblast contribute to bone metabolism and express glutamate receptors. The VGluT+terminals may effect to the bone metabolism as an extrinsic neural source of glutamate. I have been continuing to identify parent neurons of the VGluT+.
