 ====dermatomes of the head====
   *unlike the rest of the body (which uses spinal dermatomes), facial sensation is carried by the three main branches of the trigeminal nerve:
-    *ophthalmic division (V₁):
+    ***ophthalmic division (V₁): **
       * covers the forehead, scalp (up to the vertex), upper eyelids, cornea, and the bridge/dorsum of the nose.
       * ophthalmic [[zoster]] involves these areas and if the tip of the nose is involved this highly suggests involvement of the cornea via the nasociliary branch
-    * maxillary division (V₂):
+    * **maxillary division (V₂):**
       * covers the lower eyelids, cheeks, nasal cavity, upper lip, upper teeth, and a portion of the temporal area
-    * mandibular division (V₃):
+    * **mandibular division (V₃):**
       * covers the lower lip, lower teeth, chin, jawline, and the skin in front of the ear
-  * C1 has no cutaneous dermatome
+  * **C1 has no cutaneous dermatome**
-  * C2: covers the posterior and superior-posterior aspect of the head (the back of the head and scalp in a C-shape around to the ears)
+  * **C2:** covers the posterior and superior-posterior aspect of the head (the back of the head and scalp in a C-shape around to the ears)
