𝐄𝐱𝐜𝐞𝐩𝐭𝐢𝐨𝐧 𝐫𝐮𝐥𝐞𝐬 𝐢𝐧 𝐭𝐡𝐞 𝐨𝐫𝐚𝐥 𝐜𝐚𝐯𝐢𝐭𝐲: 👍
1. All tongue muscles are supplied by the “hypoglossal nerve” EXCEPT 𝖕𝖆𝖑𝖆𝖙𝖔𝖌𝖑𝖔𝖘𝖘𝖚𝖘, which is supplied by the cranial part of the accessory nerve through the pharyngeal branch of the vagus nerve.

2. All muscles of the palate are supplied by the “cranial part of the accessory nerve through the pharyngeal branch of the vagus” (pharyngeal plexus) EXCEPT 𝖙𝖊𝖓𝖘𝖔𝖗 𝖕𝖆𝖑𝖆𝖙𝖎 which is supplied by the nerve to medial pterygoid (mandibular nerve).

𝐃𝐞𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐨𝐟 𝐭𝐡𝐞 𝐬𝐢𝐝𝐞 𝐨𝐟 𝐩𝐚𝐫𝐚𝐥𝐲𝐬𝐢𝐬:
1. Injury of the hypoglossal nerve leads to deviation of the "𝐭𝐨𝐧𝐠𝐮𝐞" toward the PARALIZED SIDE (injured side) during protrusion of the tongue.

2. Injury of the fibers of the cranial part of the accessory nerve which runs through the vagus nerve leads to paralysis of the muscles of the palate which is manifested by deviation of the “𝘂𝘃𝘂𝗹𝗮” toward the HEALTHY SIDE.
