Neuroanatomy — Flashcards

Contents of superior orbital fissure (within the common tendinous ring): - _____ - Abducens nerve - Nasociliary nerve (Mnemonic: BAN)

Rules of 4: There are four _____ structures that start with 'M'1. Motor pathway (corticospinal tract)2. Medial lemniscus 3. Medial longitudinal fasciculus (MLF) 4. Motor nuclei/nerves (CN III, IV, VI, XII)

_____ to a site of CNS or PNS axon injury there is anterograde (Wallerian) degeneration

Neuroblastoma originates from _____ cells and can occur anywhere along the sympathetic chain

The fasciculus _____ carries input from the spinal level T6 and above

_____ visceral efferent column contains neurons innervating muscles developed from the pharyngeal arches: Motor nucleus of V nerve: innervating muscles of masticationMotor nucleus of VII nerve: innervating muscles of facial expressionNucleus ambiguus ( IX, X, XI): innervating stylopharyngeus, pharyngeal, external laryngeal and oesophageal striated muscles

Hint: G/S

The _____ region of the spinal cord supplied by the anterior spinal artery territory is a watershed area, as the artery of Adamkiewicz anatamoses with the ASA to supply T9 to the Conus Medullaris

The _____ segment of facial nerve runs above the oval window (stapes) and below the horizontal/lateral semicircular canal.

Layers _____ of the LGB receive the projections of the axons from the nasal retina of the contralateral eye (crossed fibres)

Foramen of the skull:The _____ nerve, a branch of facial nerve carries the preganglionic parasympathetic fibres to the pterygopalatine ganglion
