what comes in at the base of the pons? - answer-trigeminal nerve (CN V)
pineal body - answer-aka epithalamus
superior and inferior colliculus - answer-superior - visual map of world
inferior - auditory map of world
superior cerebellar peduncle - answer-connects midbrain to cerebellum
middle cerebellar peduncle - answer-connects pons to cerebellum
inferior cerebellar peduncle - answer-connects medulla to cerebellum
interpeduncular fossa - answer-Space between the cerebral peduncles; CN III
emerges from it
pyramids - answer-corticospinal pathways
,pyramidal decussation - answer-in caudal medulla, where lateral corticospinals
cross midline
basilar region - answer-anterior portion of brainstem; mostly motor structures
- descending tracts, motor nuclei, substantia nigra
medial longitudinal fasciculus - answer-fiber tract that coordinates head + eye
movements
tectum contains: - answer-superior + inferior colliculi
pretectal area
inferior olivary nucleus - answer-located in rostral medulla
- perception of time
pons contains: - answer-- cortico-bulbar, -pontine, and -spinal tracts
- pontine nuclei
- pontocerebellar tract
- middle cerebellar peduncle
pontocerebellar tract - answer-cerebral cortex
> corticopontine tract
>> pontine nuclei
>>> pontocerebellar tract
>>>> cerebellum
,midbrain contains the following structures: - answer-- cerebral peduncles
- red nucleus
- substantia nigra
- medial lemniscus + spinolthalamic tracts
- periaqueductal gray
- oculomotor nucleus
- tectum
cerebral peduncles contain what tracts? - answer-- corticobulbar
- corticospinal
- corticopontine
location of cranial nerve I (olfactory)
- where it enters CNS - answer-cerebrum
where does CN II (optic) enter CNS? - answer-diencephalon
where do CN III + IV exit/enter CNS? - answer-midbrain
where does CN V exit CNS - answer-pons
where do CN VI, VII, VIII exit CNS? - answer-pontomedullary border
where do CN IX, X, XI, XII exit the CNS? - answer-medulla
, 3 main functions of cranial nerves - answer-1. motor (face, eyes, tongue, jaw,
neck)
2. somatosensory (touch, smell, sight, hearing, taste, balance, visceral)
3. parasympathetic regulation
damage to cranial nerve in periphery:
- causes
- leads to: - answer-trauma or inflammation
- ipsilateral deficits
damage to cranial nerve nuclei in CNS
- cause
- leads to: - answer-stroke
- usually ipsilateral deficits
tegmentum - answer-posterior part of brainstem
tectum - answer-only in midbrain
- roof over cerebral aqueduct
tegmentum contains: - answer-- cranial nerve nuclei
- reticular formation
- ascending sensory tracts + nucllei
