Relations: Laterally: Mandibular Nerve Medially: Tensor palate muscle Posteriorly: Middle meningeal artery Anteriorly: Medial Pterygoid muscle Roots: Motor: From the nerve to medial pterygoid muscle Sensory: Lesser superficial petrosal N (Fibres from 7th and 9th Nerves) Sympathetic: From plexus around middle meningeal artery Branches: It gives branches that give motor supply to tensor tympani and tensor palatine muscles Secretory: To auriculo-tempral nerve which carries secretory fibres to parotid gland. To inferior maxillary nerve, making its motor root. Communications: To auriculo-temporal…
