Ch. 9 Brainstem

Front 1

Pons
1. consists of 2 parts
2. gives rise to which cranial nerves

Back 1

1. base (cortico-bulbar, -spinal, and -pontine fibers) and tegmentum (cranial nn. nuclei, reticular nuclei, ascending sensory paths)
2. 5-8

Front 2

Pons
cranial nerve nuclei

Back 2

1. cochlear nuclei of CN 8
2. abducent nucleus (underlies facial colliculus; contain lateral gaze center)
3. facial nucleus and superior salivatory nucleus of CN 7
4. spinal trigeminal, motor, prencipal sensory, and mesencephalic nuclei of CN 5

Front 3

Locus ceruleus
-location
-contains..
-projeccts..

Back 3

-midbrain and pons
-melanin
-noradrenergic axons to CNS

Front 4

Midbrain
-mediates..
-contains which cranial nerves
- 3 parts

Back 4

-visual and auditory reflexes
-CN 3 and 4
-tectum (sup/inf colliculi), tegmentum (cranial nn. nuclei), and base (crus cerebri)

Front 5

Midbrain: 4 structures unique to the level of the inferior colliculus

Back 5

inferior colliculus, trochlear nuclus, decussation of SCP, interpeduncluar nucleus

Front 6

Midbrain: 4 structures unique to the level of the superior colliculus

Back 6

superior colliculus, oculomotor nucleus, EW nucleus, red nucleus,

Front 7

Midbrain: level of the posterior commissure (pretectal region)

Back 7

1. posterior commissure (marks transition of 3rd ventricle to cerebral aqueduct)
2. pretectal nuclei (pupillary light reflex)

Front 8

Midbrain
-largest nucleus (degeneration results in what?)
-contains what formation (damage results in what?)
-contains what center?

Back 8

-substantia nigra (Parkinsons)
-paramedian reticular formation (Coma)
-vertical conjugate gaze center
