brainstem and cranial nerves Flashcards
cranial nerve origins: explain the origins of the cranial nerves and explain how this relates to development of the brainstem
cranial nerve nuclei: sensory midbrain (lateral)
trigeminal (general somatic afferent)
cranial nerve nuclei: sensory pons (lateral)
trigeminal (general somatic afferent), vestibulocochlear (special somatic afferent; most lateral; down to medulla also)
cranial nerve nuclei: sensory medulla (lateral)
trigeminal (general somatic afferent; up to pons and down to cervical spinal cord also), solitarius (general/special viceral afferent; most medial; up to pons also)
cranial nerve nuclei: motor midbrain (medial)
Edinger Westphal (general visceral efferent; most lateral - PSNS innovation of eye), oculomotor (general somatic efferent; most medial), trochlear (general somatic efferent; most medial)
cranial nerve nuclei: motor pons (medial)
trigeminal (special visceral efferent), abducens (general somatic efferent; most medial), facial (special visceral efferent), salivatory (general visceral efferent - PSNS; most lateral)
cranial nerve nuclei: motor medulla (medial)
salivatory (general visceral efferent - PSNS; most lateral), vagus (general visceral efferent - PSNS; most lateral), ambiguus (pharynx and larnx: special visceral efferent), hypoglossal (general somatic efferent; most medial)
cranial nerve nuclei: motor cervical spinal cord (medial)
accessory (special visceral efferent)
nucleus solitarius
