SSA
GSA
Laterally
▪ GSE: oculmotor, trochlear,
abducent & hypoglossal nuclei
▪ SVE: trigeminal motor, facial
motor, ambiguus & accessory spinal nuclei
▪ GVE: accessory oculmotor, sup.

The Internal Structure of Brainstem
OUTLINE
▪ Gray Matter - Cranial Nerve Nuclei - Relay Nuclei
▪ White Matter - Ascending Tracts - Descending Tracts
▪ Reticular Formation ▪ Transverse Sections
▪ GSE column (SE column) ▪ SVE column (branchial efferent column) ▪ GVE column – parasympathicus ▪ GVA column – subconscious sensation ▪ SVA column – taste sense ▪ GSA column – conscious sensation ▪ SSA column – audition & posture
(mesencephalic, principal / main & spinal) nuclei
▪ SSA: vestibular & cochlear nuclei
Motor Cranial Nerve Nuclei
▪ GSE: oculmotor, trochlear, abducent & hypoglossal nuclei ▪ SVE: trigeminal motor, facial motor, ambiguus nuclei (& accessory spinal) ▪ GVE: accessory oculmotor, sup. & inf. salivatory & dorsal motor vagus
GSE: Oculomotor Nucleus – at the level of the superior colliculus of midbrain Trochlear Nucleus – at the level of the inferior colliculus of the midbrain Abducent Nucleus – beneath the fascial colliculus Hypoglossal Nucleus – beneath the hypoglossal trigone
Ventral View
▪ Medulla Oblongata
- anterior medial fissure - pyramid - olive - pyramidal decussation
▪ Pons
- basilar sulcus - basilar part - middle cerebellar peduncle
▪ Midbrain
- corpora quadrigemina - pineal body
▪ Medulla Oblongata
- gracile tubercle - cuneate tubercle - trigeminal tubercle
The Continuation of Brainstem & Spinal Cord
▪ Midbrain
- cerebral peduncle - interpeduncular fossa - posterior perforated substance
External Features of Brainstem
Dorsal View
▪ Rhomboid Fossa
- dorsal median sulcus - striae medullares - sulcus limitans - medial eminence - fascial colliculus - vestibular area - hypoglossal trigone - vagal trigone
(Rhomboid Fossa & Fourth Ventricle)
