Document Summary
Anterograde transport, walking from soma to axon terminal using the protein kinesin, retrograde transport, walking from axon terminal to soma using the protein dynein, microtubules, make the shape of a cell and thus determine its function. Changing shape cell death: more important means it ends up closer to the cell, branches off at acute angles, mental retardation occurs without dendrites. Terminals release while dendrites just have receptors: vesicles carry many neurotransmitters, densely packed. Action potential causes them to be released: bcr, neurotransmitters bind, cause a conformational change, glia: about the same number of neurons, include astrocytes, which act as potassium sinks to keep out toxic things. If trauma is applied, the astrocytes become migratory and phagocytic, eating up our bad toxins. Too much potassium will stop neural activity: glia is in charge of myelination. 2 major types of myelin include schwann cells and. Bipolar if an axon and dendrite: multipolar if an axon and multiple.
