OBJECTIVE
To study the distribution of substance P-like immunoreactive fibers in feline temporomandibular joint.
METHODS
The immunohistochemical PAP method was used for the investigation of the distribution of substance P-like immunoreactive fibers in feline temporomandibular joint.
RESULTS
The TMJ capsule and the anterior and posterior disc attachments all contained SP-immunoreactive nerve fibers, but the medium fibers in diameter were mainly observed. The density of the distribution of SP-positive nerve fibers was the highest in the subsynovium of the TMJ capsule. The density of distribution was similar in the anterior and posterior disc attachments, but lower than in the subsynovium and the lateral joint capsule. Such fibers in the synovial membrane were sparser, and a part of the fibers were seen around the thin blood vessels in all the foregoing tissues.
CONCLUSION
These results provide the morphological data for exploring the neurobiological mechanisms of temporomandibular joint disorder and its pain.
