[Oral nerve endings in the cat]
Journal De Biologie Buccale
|June 1, 1978
Summary
Oral nerve endings in cats, including the palate, buccal mucosa, and periodontal ligament, feature a cellular envelope. Specialized structures in the ligament are likely nerve endings, not receptors, and are also found in other oral tissues.
Area of Science:
- Neuroscience
- Oral Biology
- Histology
Context:
- Investigating the innervation of feline oral tissues.
- Characterizing the cellular structures of oral nerve endings.
Purpose:
- To identify and describe the morphology of oral nerve endings in the cat palate, buccal mucosa, and periodontal ligament.
- To clarify the nature of end-ring structures within the periodontal ligament.
Summary:
- Oral nerve endings in cats possess a cellular envelope, the terminal form of the Henle sheath.
- Structures previously termed 'end-rings' in the periodontal ligament are identified as subterminal nerve structures, not specific receptors.
- Similar nerve structures, including Vater-Pacini type mechanoreceptors, are present in the palate and buccal mucosa, indicating shared innervation patterns.
Impact:
- Provides detailed histological characterization of feline oral nerve endings.
- Refines the understanding of mechanoreceptors and nerve structures in the oral cavity.
- Contributes to comparative neuroanatomy and the study of sensory innervation in mammals.
