Motor end plate - Study guides, Class notes & Summaries

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...

Phosphatase correct answers This myosin-actin interaction forms the basis of the cross-bridge cycle (CBC), which causes muscle contraction, as in skeletal -bridge cycling (CBC) requires phosphorylation of the myosin light chain (LC20). A .............. is an enzyme that removes a phosphate group from its substrate composed of actin and are dynamic and are lengthen by polymerization or shortened by depolarization correct answers microfilaments are provide strucule support for the cell ...
