Action potential, Graded potential GRADED POTENTIAL -resulting change in membrane potential is small -vary in size -can be positive and negative ACTION POTENTIAL —70mv~threshold voltage of -55mV triggers the action potential at the axon hillock, which then travels down the axon 1. Dendrites/cell body 에서 graded potential 접수 by ligand-gated/ mechanically-gated ion channel 2. Axon hilock 에 있는 voltage-gated channel 에서 Action potentia.. 2022. 12. 5. CRANIAL NERVE 2022. 12. 2. Cell juctions CELL JUNCTIONS 1. Gap juction : transporting ions.. 2. Adherence juction : support structure, stick cells to each other 3. Tight juction : limit the passage of molecules and ions through the surface of between cells TIGHT JUNCTIONS They consist of a network of claudins and other protiens. They limit the passage of molecules and ions through the surface between cells. So most materials must actua.. 2022. 11. 21. 이전 1 다음 반응형
