Title: An action potential enters the presynaptic terminal ... voltage-gated channels open Post by: big-e_7 on Feb 9, 2012 PLEASE HELP ME FIGURE OUT THE BLANKS....THIS IS A FLOW CHART!!!! ???
An action potential enters the presynaptic terminal-------> voltage-gated channels open and______&_______ions enter the presynaptic terminal------->_________ions cause_________to fuse with the presynaptic membrane-------->___________is liberated into the synaptic cleft-------->The neurotransmitter reacts with_________on the muscle membrane (Then it has 2 arrows split left and right)(LEFT SIDE) Channels open and the muscle membrane________---------> this produces an ______ ______ in the muscle membrane (RIGHT SIDE) The neurotransmitter is broken down by ______ _______in the synaptic cleft--------->________is taken up into the presynaptic cell. Title: An action potential enters the presynaptic terminal ... voltage-gated channels open Post by: duddy on Feb 12, 2012 An action potential enters the presynaptic terminal--->Voltage-gated channels open and Sodium and Potassium ions enter the presynaptic terminal--->Sodium ions cause vesicular membrane to fuse with the presynaptic membrane---->Neurotransmitter is liberated into the synaptic cleft.
Acetylcholine is secreted into the cleft by the motor axon---> The neurotransmitter reacts with vesicles on the muscle membrane---->Channels open and the muscle membrane closes---> The neurotransmitter is broken down by presynaptic membrane in the synaptic cleft--->Neurotransmitter is taken up into the presynaptic cell. Acetylcholine binding opens the channels and the muscle membrane becomes open--->This creates an action potential which travels along the muscle's surface--->The action potential travels down the neuron and stimulates voltage-sensitive ion channels--->Calcium ions are release into the sarcoplasm from the calcium channels--->Calcium binds to receptors--->Acetylchoine moves to expose the myosin binding sites on actin--->Cross bridge cycling causes the sarcomeres to contract--->Calcium is taken up into the sarcoplasmic reticulum to terminate the contraction.
