|
SCP, MCP & ICP |
Cerebellar peduncles: Inferior - info from medulla Middle - info from cortex into cerebellum (huge) Superior - only efferent |
|
|
Auditory info pathway |
Goes bilaterally: Cochlear nucleus -> crosses midline in trapezoid body Ascends (bilaterally) via lateral lemniscus, inferior colliculus, medial geniculate, auditory cortex |
|
|
|
|
|
Corticobulbar pathway |
Bilateral innervation except for lower face (contralateral) UMN - only contralateral lower face affected; LMN (facial n) - both upper & lower face affected contralaterally |
|
|
CN V in mid-pons |
Enters brainstem & meets w motor: Motor - like DCP (more medial) Spinal nucleus - like spinothalamic (more lateral) |
|
|
MLF |
Connects CN III & VI for lateral gaze - center of pons, through medulla |
|
|
Mastication nerves & only primary sensory neuron in CNS |
|
|
|
Locked-in syndrome |
blockage of basilar artery; all corticospinal & corticobulbar knocked out - no control of cranial nuclei & movement |
