Brainstem and Cranial Nerves
Cards in this deck (11)
- 1Midbrain-Substantia nigra: PD; abnormal movement
-Connection between brain and PNS
-3 CN nuclei - 2Pons-7 CN nuclei
-All ascending motor fibers and ascending sensory fibers
-Reticular formation
-Bilateral damage (from basilar artery stroke) - 3Medulla Oblongata-Descending motor (pyramidal) tracts
-Ascending sensory tracts
- - 4General Somatic Efferent (GSE)Controls muscles derived from somites (skeletal, extraocular, glossal)
- 5General Somatic Afferent (GSA)Mediates somasthetic input (pain, temperature, touch) from muscles, skin, ligaments, and joints
- 6General Visceral Efferent (GVE)Sends preganglionic axons to peripheral to peripheral parasympathetic ganglia which regulate autonomic functions of smooth muscles, cardiac muscles, glands
- 7General Visceral Afferent (GVA)Mediates sensations of pain, temperature, tissue stretch, and pressure from visceral organs
- 8Special Somatic Afferent (SSA)Conducts special sensory mechanism of vision from retina and audition and equilibrium from inner ear includes spindle afferents and golgi tendon organs afferents
- 9Somatic Special Visceral (SSV)Controls gill-related muscles of face, larynx, pharynx, and neck
- 10Special Visceral Afferent (SVA)Mediates information from specialized receptors related to taste from tongue and pharynx, olfaction, from nasal mucosa
- 11Classifications of CNs: Information types, Muscles types, Fiber types-Information types: General and special
-Muscle types: Somatic (skeletal) and visceral (organs, nonstriated muscle,
