Oral Anatomy & Histology — Key differences for NEET MDS
Trigeminal V = main sensory nerve head face. V1 Ophthalmic = sensory only forehead. V2 Maxillary = sensory only midface. V3 Mandibular = only division with motor and sensory. Lingual nerve = taste anterior two-thirds via chorda tympani from VII. IAN block anesthetizes V3 = IANB. Facial nerve VII = motor muscles of facial expression. Marginal mandibular branch = important surgical landmark.

Tomes process = secretory end of ameloblast. Hunter-Schreger bands = enamel prism direction change light dark. Contour lines of Owen = incremental lines dentin. Neonatal line = birth line in enamel and dentin.
