Soft Palate and Its Motor Innervation: A Brief Review
Anatomy Physiology & Biochemistry International Journal Juniper Publishers Author By: Liancai Mu Abstract Human soft palate plays an important role in upper airway functions such as speech, swallowing and respiration. However, neural control of the soft palate is poorly understood because innervation of this structure has long been controversial. In this review, the inconsistent and even contradictory observations regarding the motor innervation of the palatal muscles are summarized. We emphasize to use Sihler’s stain for documenting the nerves and their supply patterns within individual palatal muscles as studies have demonstrated that Sihler’s stain permits mapping of entire nerve supply within organs, skeletal muscles, mucosa, skin, and other structures. This wholemount nerve staining has unique advantage over other anatomical methods as all the nerves within the muscles processed with Sihler’s stain can be visualized in their 3-dimensional positions.
