  1. INERVASI SENSORIK Dr. Mona Amelia, MBiomed

  2. Definisi Reseptor Ganglion Posterior Akson • Suatusistemhantaranimpulsdariperifer susunansarafpusat Radix Posterior MS Persepsi Cornu Posterior MS Cortex Cerebri TractusSpinothalamicus Corona Radiata Thalamus

  3. KASUS KHUSUS • Beberapa organ sensorik diferensiasitingkattinggi • ORGANON SENSES • Reseptorkhusus (retina, utriculus, sacculus, vibrissae, tastebud, nociceptor, corpusculum Meissneri, thermoreceptor, corpusculum Paccini) • Ganglion  nucleus khususintra cranial

  4. InervasiSensorikPerifer • Reseptor • Akson (serabutsarafperifer) • Ganglion sensorik • Neuron ordo 1

  5. InervasiSensorikSentral • Cornu posterior medulla spinalis (substansiagrisea) • Tractusspinothalamicus (substansia alba) • Neuron ordo 2 • Thalamus • Corona radiata (substansia alba) • Cortex cerebri (substansiagrisea) • Neuron ordo 3

  6. Thalamus ganglion Tr. spinothalamicus akson Neuron ordo 1 Cornu posterior reseptor Neuron ordo 2

  7. Corona radiata Cortex cerebri

  8. ReseptorPerifer • Eksteroseptif (kulit, otot) • Proprioseptif (otot, ligamentum, sendi) • Interoseptif (viscerae)

  9. TIGA SISTEM SENSORIK • Lemniscusmedialis– collumnadorsalis diskriminasiraba, posisisendi, getar/ vibrasi • Tractusanterolateral diferensiasi rasa raba, nyeri, suhu • Tractus trigeminal diferensiasiraba, nyeri, suhudarikepala

  10. Terminal AkhirJarasSensorik • Informasi aferen yang disadari  thalamus  cortex cerebri  interpretasi/ persepsi • Informasi aferen yang tidak disadari • cerebellum  koordinasi otot • reflek spinal lokal • Informasi aferen lain • mesencephalon  reflek visual • formatio reticularis

  21. Thalamus • Pada thalamus  modifikasiimpulsnyeri • Nucleus thalami  capsulainterna  corona radiata  gyruspostcentralis (homunculus cerebri), area asosiasi 1 dan 2 dilobusparietalis

  22. FORMATIO RETICULARIS • Pusatjaga, kesadaran, danwaspada • Pusatrespirasidankardiovaskuler MO • Pusatmotorikterpadu (tractuscortico-reticulo-spinal)  pons • Sistemproyeksiascendens (ARAS, Ascending Reticulare Activating System)  kewaspadaan • NNcc. precerebellaris  hubunganbatangotakdengan cerebellum, keseimbangan

  23. FR DIVISI LATERAL • Sistemanterolateral • Sistem trigeminal • Sistemauditorik • Sistem visual
