This high-yield revision note on 15 Mnemonics for Cranial Nerves, Foramina & Infratemporal Fossa You Will Never Forget covers everything examiners typically test under Oral Anatomy & Histology — structured as quick-reference tables, clinical correlations, mnemonics and previous-year-style high-yield points. It's built for last-mile revision before NEET MDS, INI-CET MDS and INBDE, so you can scan it in minutes instead of re-reading a whole textbook chapter.
| # | Topic | Mnemonic / Trick |
|---|---|---|
| 1 | Cranial nerve order (I-XII) | "Oh Oh Oh To Touch And Feel Very Good Velvet, AH!" (Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory, Hypoglossal) |
| 2 | Cranial nerve type (S/M/Both) | "Some Say Marry Money, But My Brother Says Big Brains Matter More" |
| 3 | Foramen rotundum | "Rotundum is Round for V2" - carries the maxillary nerve |
| 4 | Foramen ovale | "Ovale is Oval for V3" - carries the mandibular nerve, accessory meningeal artery, lesser petrosal nerve |
| 5 | Foramen spinosum | "Spinosum = Spinal, brings the meningeal artery" - middle meningeal artery + nervus spinosus |
| 6 | Jugular foramen | "9, 10, 11 leave through Jugular" - Glossopharyngeal, Vagus, Accessory (+ IJV) |
| 7 | Superior orbital fissure | "LFT SAN" mnemonic for structures - Lacrimal, Frontal, Trochlear, Superior/inferior division of oculomotor, Abducens, Nasociliary nerves |
| 8 | Infratemporal fossa boundaries | "Behind the maxilla, below the temporal fossa" - roughly bounded by the ramus of mandible laterally, lateral pterygoid plate medially, and the infratemporal surface of the maxilla anteriorly |
| 9 | Contents of infratemporal fossa | "MMM-PLAN" - Muscles of mastication (medial/lateral pterygoid, part of temporalis), Maxillary artery, Mandibular nerve branches, Pterygoid venous plexus, chorda tympani (Lingual nerve joins here), Auriculotemporal, otic ganglioN |
| 10 | Maxillary artery parts | "MPP" - Mandibular part (1st), Pterygoid part (2nd), Pterygopalatine part (3rd) - roughly divided by the lateral pterygoid muscle |
| 11 | Muscles of mastication elevators | "MTP elevate, LP depresses/protrudes" - Masseter, Temporalis, Medial pterygoid CLOSE the jaw; Lateral pterygoid OPENS/protrudes it |
| 12 | Otic ganglion relations | "Otic sits below Foramen Ovale, medial to the mandibular nerve" - receives preganglionic fibers from the lesser petrosal nerve (from IX) and gives secretomotor supply to the parotid via the auriculotemporal nerve |
| 13 | Pterygomandibular space contents | "Lingual, IAN, mylohyoid nerve" - key landmark for the inferior alveolar nerve block |
| 14 | Middle meningeal artery course trick | Enters skull via foramen spinosum, runs in a groove on the internal surface of the pterion - the pterion is the THINNEST part of the skull, making this artery vulnerable to extradural hemorrhage in temporal trauma |
| 15 | Hard palate innervation | "Greater Palatine goes Back, Nasopalatine goes Front" - Greater palatine nerve supplies posterior 2/3 of hard palate, nasopalatine supplies the anterior premaxillary triangle |
