Reticular formation |
Center of brainstem: (if lesion - coma) BP, HR, resp, descending pathways - (pain & motor - influence LMN), neurotransmitters synthesized |
|
|
Motor nuclei of brainstem |
Somatic motor nuclei (Medial): CN III, VI, XII Branchial motor nuclei (Lateral): motor nucleus of V, facial nucleus, nucleus ambiguus (IX & X), XI |
|
caudal pons |
|
|
Mid pons |
|
|
|
Caliculi |
Inferior - part of auditory pathway Superior - auxiliary visual pathway Superior cerebellar peduncle - from cerebellum, cross, to midbrain |
|
|
Latreral brain stem lesion - often see: |
Horner syndrome (parasympathetic travels in lateral part of reticular formation) |
|
|
Locus coeruleus: |
Supplies most of brain and CNS with noradrenergic neurons (Blue) - widespread - attention and vigilance |
|
caudal midbrain |
|
|
rostral midbrain |
|
|
|
Cause of Parkinson's disease |
Loss of dopamine neurons in substantia nigra (will see symptoms when >80% gone) |
|
|
Medial Midbrain Syndrome |
Contralateral paralysis: Long tract - CBT & CST CN III - lateral deviation of eye at rest CBT - UMN - contralateral lower muscles of facial expression |
|
|
Edinger Westphal |
