18 sie 2024 · accessory nerve (CN XI) hypoglossal nerve (CN XII) In adults, the brainstem nuclei are located within the tegmentum, the posterior section of the brainstem (except in the midbrain where the quadrigeminal plate is most posterior). See mnemonic for cranial nerves.
Lateral to CN VII (cerebellopontine angle) Located in the internal acoustic canal. Mediates sensation of sound, rotation, and gravity (essential for balance and movement). More specifically, the vestibular branch carries impulses for equilibrium and the cochlear branch carries impulses for hearing. IX Glossopharyngeal: Both sensory and motor ...
3 lis 2023 · Glossopharyngeal nerve (CN IX) Cranial nerve 9 is another multimodal nerve. It originates from the brainstem and leaves the skull through the jugular foramen. It enables swallowing, salivation, and taste sensation, as well as visceral and general sensation in the oral cavity.
There are many branches, which transmit a combination of sensory, motor and parasympathetic fibres. The other cranial nerves are the vestibulocochlear, the glossopharyngeal, the vagus, spinal accessory and hypoglossal nerves.
