mekanisme kontraksi dan relaksasi otot

1. Mekanisme Kontraksi dan Relaksasi Otot NUR RABIYATUL AWALIYAH PROGRAM STUDI ILMU BIOMEDIK UNIVERSITAS HASANUDDIN

2. Interaksi jembatan silang antara aktin dan miosin sehingga menyebabkan kontraksi otot Potensial aksi suatu otot yang memicu proses kontraksi otot Sumber Ca²⁺ yang mereposisi troponin dan tropomiosin agar terjadi pengikatan jembatan silang

3. Aktivitas jembatan silang

4. P erubahan pola lurik sewaktu proses pemendekan Sewaktu otot berkontraksi , setiap sarkomer memendek karena filamen-filamen tipis bergeser saling mendekat di antara filamen filamen tebal sehinga garis-garis Z tertarik semakin mendekat satu sama lain. Lebar pita A tidak berubah sewaktu otot memendek , tetapi pita I dan zona H menjadi lebih pendek .

5. Peran kalsium dalam mengaktifkan jembatan silang

6. Hubungan miofibril dengan tubulus T dan retikulum sarkoplasma Disetiap pertemuan pita A dan pita I, membran permukaan masuk kedalam otot untuk membentuk tubulus transversus ( tubulus T) yang berjalan tegak lurus dari membran sel otot kedalam bagian tengah serat otot .

7. Siklus jembatan silang

8. Penggabungan eksitasi-konstraksi dan relaksasi otot Tahap 1 hingga 7 memperlihatan kejadian-kejadian yang menyatukan pelepasan neurotransmiter dan eksitasi listrik yang kemudian terjadi di sel otot pada waktu kontraksi kontraksi otot . Pada tahap 7, jika Ca2+ masih ada jembatan silang kembali ke langkah 5 untuk terjadinya kayuhan kuat lainnya . Jika Ca2+ tidak lagi ada akibat konsekuensi tahap 8, terjadinya relaksasi .

12. Introduction Mercury takes a little more than 58 days to complete its rotation, so try to imagine how long days must be there! Since the temperatures are so extreme, albeit not as extreme as on Venus, Mercury has been deemed to be non-habitable for humans Mercury is the closest planet to the Sun and the smallest one in the entire Solar System. Contrary to popular belief, this planet's name has nothing to do with the liquid metal. Mercury was, instead, named after the famous Roman messenger god Mercurius
