  4. StrukturOtotPolos 􀂄 Bentukfusiform, panjang ± 0.2 mm, ø 5-6 μm 􀂄 Punya satu inti terletak ditengah 􀂄 Pembungkussel ~ ototrangka 􀂄 Tersusundlmlapisansel ( bagiantebalselberdampingandgn ujungseldisebelahnya)􀃆 potongan transversal adaygberintidanadayg tidak

  5. MekanismeKerjaOtotPolos 􀂄 Kontraksiinvolunter, lambat, tetapibisabertahan dalamwaktu lama disebabkanolehsusunan myofilamenygkhas pd ototpolos 􀂄 Dense body ~ Z-disk 􀂄 Struktur myosin ygkhas 􀃆 banyak area perlekatan aktindgn myosin􀃆 kontraksilebih lama 􀂄 Thin filamentanpatroponin 􀂄 Kekuatankontraksiditeruskandarimyofilamen􀃆 dense body􀃆 intermediate filamen􀃆 selmemendek

  6. StrukturOtotLurik Selbentuksilindris, panjang > 4 cm, 10-100 μm, inti sel > satu, mrpgabunganmyoblasts 􀂄 Sebagianbesarsarkoplasmaterisioleh myofibril 􀃆 gambaran garis gelap dan terang 􀂄 Inti oval terletakdipinggir sel. 􀂄 >> myoglobin 􀃆 warnamerah 􀂄 > glikogen (cadanganenergi) 􀂄 Dgnmikroskopcahaya : 􀂄 Pita gelap = A bands 􀂄 Pita terang = I bands 􀂄 Z line = garis yang membagi I bands 􀂄 Area diantara 2 Z line = sarkomer􀃆 unit kontraktil

  7. StrukturOtotJantung 􀂄 Panjangsel 80 μm dan ø 15 μm 􀂄 Nukleussatu, bulat, letakditengah 􀂄 Cardiac myoctesbercabang 􀂄 Padapotongantranversalukuranseltidaksama

  8. MekanismeKerjaOtotJantung 􀂄 Kontraksi bersifat ritmik dan involunter 􀂄 Kontraksiritmikdiaturoleh pace maker 􀂄 Sumberutama calcium untukmemicu kontraksidaricairan extra cell 􀂄 Fast sodium channels dan calcium-sodium channel (slow sodium channel)􀃆 aksi potensialmudahterpicu
