occulomotor nucleus
|
skeletal M. and para neurons
para comes from edinger westphal nucleus At sup. midbrain area ventral tip of central grey matter see superior colliculus, red nicleus exits in interpeduncular fossa |
|
|
edinger westphal nucleus
|
sends para fibers through the Occulomotor nucleus
located behind 3 nucleus innervates most of the muscles in the eye |
|
|
trochlear nucleus
|
located in the lower midbrain ventral portion of periagueductal grey
se inf. colliculus, SCP decussation, and basis peduncle fibers decussate posteriorly and innervate contalaterally exit dorsally above pontomesencephalic junction innervates the superior oblique muscle |
|
|
abducens nucleus
|
at the level of the pontomedullary junction
look for facial verve going around it posterior medial tegmentum see top portion of the basilar pons innervates lateral rectus m. |
|
|
trigemminal system
|
motor nerves are found in the upper pons ventral to the superior cerebellar peduncle
motor fibers join snesory fibers two nucleus, medial is motor, outer sensory |
|
|
