Oral Anatomy & Histology — Key differences for NEET MDS
Ameloblasts = ectodermal origin = enamel formation. Odontoblasts = neural crest ectomesenchyme = dentin formation. Enamel = most mineralized tissue 96 percent inorganic. 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.

Lateral pterygoid = opens mouth protrusion depression. Inferior head lateral pterygoid = active in opening. Superior head = active in closing. Articular eminence = slope guides condylar movement.
