Neuroanatomy
| Question | Answer |
|---|---|
| Enters brain stem where | Pontomedullary junction |
| Fibers crossed at the trapezoid body and terminate in | Superior olivary nucleus |
| Some of the fibers cross at the dorsal and intermediate acoustic tria and end where? | Lateral lemniscus |
| Uncrossed fibers travel to | ipsilateral lateral lemniscus or superior olivary nucleus |
| from the lateral leminiscus | pons to inferior colliculus in midbrain |
| Acends to thalamus through | Internal Capsule to Heschl's Gyrus |
| Sense receptor | Cochlea/ cilia |
| PNS | CN VIII: Vestibocochlear |
| Enters CNS | Pontomedullary junction |
| Primary cortical area | Heschl's gyrus |
| Association cortical area | superior/medial temporal gyri, Wernicke's area |
| static | maintaining balance at rest |
| dynamic | maintaining balance at acceleration and deceleration of movement |
