(2016). Human Physiology: From Cells to Systems. 9th Edition: Cengage Learning. QUICK QUESTION! Mengapa impuls saraf disebut sebagai “all or none”? Karena neuron punya threshold! Sel-sel saraf mengirimkan sinyal dengan kekuatan yang sama terlepas dari kekuatan impulsnya. Dengan ini, informasi penting tidak kehilangan kekuatannya saat dibawa ke otak.  Faktor Yang Memengaruhi Laju Potensial Aksi EP NEF21N Physiology Assistant 2023/2024 MYELIN Lebih cepat pada akson yang bermielin DIAMETER AKSON Diameter besar > permukaan luas > lebih cepat  EP NEF21N Physiology Assistant 2023/2024 SINAPS SINAPS LISTRIK Oleh ion-ion pembawa muatan yang mengalir secara langsung dari sel pertama ke sel kedua, atau sebaliknya (bisa arah bolak-balik) Sherwood, L.
