Look it up now! axon hillock (plural axon hillocks) A specialized part of the soma of a neuron that connects to the axon. It is the last site in the soma where membrane potentials propagated from synaptic inputs are summated before being transmitted to the axon. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Nervous system - Nervous system - Axon: The axon arises from the soma at a region called the axon hillock, or initial segment. This is the region where the plasma membrane generates nerve impulses; the axon conducts these impulses away from the soma or dendrites toward other neurons. Large axons acquire an insulating myelin sheath and are known as myelinated, or medullated, fibres.

4. Joner är väldigt viktiga för att skapa elektriska impulser i en nervcell. To inject a guided mode in the myelin sheath and verify its guidance, one might need to decapitate the axon near the terminal and hillock regions, couple the voltage gradient is just enough at the axon hillock to · spänningsgradient är tillräckligt precis vid The reason for this anisotropy is that the axon membranes restrict the diffusion of potentialer till axonkäglan (“axon hillock”) -> voltkänsliga Na-portar öppnas Trevor gillar Axon Hillock.

The axon hillock is the last site in the soma where membrane potentials propagated from synaptic inputs are summated before being transmitted to the axon. For many years, it was believed that the axon hillock was the usual site of initiation of action potentials—the trigger zone.
