Fissures and Sulci

Considerable variations have been reported in the course and development of the fissures and convolutions, not only in individuals but also on opposite sides of the same brain. These variations have not shown any constant relationship to age, sex, occupation, race, or intelligence.

• Sylvian Fissure
• Postcentral Sulcus
• Intraparietal Sulcus
• Superior Temporal Sulcus
• Middle Temporal Sulcus
• Orbital Sulcus
• Olfactory Sulcus
• Central Sulcus (Fissure)
• Precentral Sulcus
• Inferior Frontal Sulcus
• Superior Frontal Sulcus
• Middle Frontal Sulcus
• Cingulate Sulcus
• Parieto-Occipital Fissure
• Calcarine Fissure
• Collateral Fissure
• Cerebral Hemispheres
• Cerebral Aqueduct
• Brain Stem
• Spinal Cord

Cranial Nerves and Ganglia

The present system for enumeration of cranial nerves (CN) was proposed by Soemmering in 1778.

• Olfactory (CN1)Nerve
• Optic (CN II) Nerve
• Oculomotor (CN III) Nerve
• Ciliary Ganglion
• Trochlear (CN IV) Nerve
• Trigeminal (CN V) Nerve--Ophthalmic Division (V1)
• Lacrimal Nerve
• Frontal Nerve
• Infratrochlear Nerve
• Ethmoidal Nerve
• Nasal (Nasociliary) Nerve
• Trigeminal (CN V) Nerve--Maxillary Division (V2)
• Infraorbital Nerve
• Posterior Superior Alveolar Nerve
• Zygomatic Nerve
• Trigeminal (CN V) Nerve--Mandibular Division (V3)
• Mandibular Nerve
• Lingual Nerve
• Buccal Nerve (N. to M. Buccinator)
• Auriculotemporal Nerve
• Inferior Alveolar Nerve
• Abducens (CN VI) Nerve
• Facial (CN VII) Nerve
• Pterygopalatine (Sphenopalatine) Ganglion
• Glossopharyngeal (CN IX) Nerve
• Vagus (CN X) Nerve
• Auricular Nerve
• Pharyngeal Plexus
• Superior Laryngeal Nerve
• Internal Laryngeal Branch of Superior Laryngeal Nerve
