30+ Events At Neuromuscular Junction

Ach binding opens ion channels in the receptors that allow simultaneous passage of na into the muscle fiber and k out of the muscle fiber.

Events at neuromuscular junction. Events at neuromuscular junction step 5. More na ions enter than k ions exit which produces a local change in membrane potential called the end plate potential. A neuromuscular junction is a synapse between a motor neuron and skeletal muscle. In order for a muscle to contract all six steps must occur in sequence as a continuous process. Crash course a p 21 duration. This lesson describes the events of synaptic transmission leading. Ann marie burke 556 views.

A neuromuscular junction or myoneural junction is a chemical synapse between a motor neuron and a muscle fiber. It allows the motor neuron to transmit a signal to the muscle fiber causing muscle contraction. You have learned about the six events at the neuromuscular junction. Muscles require innervation to function and even just to maintain muscle tone avoiding atrophy. In this activity you will place the components of the neuromuscular junction in their correct positions and then initiate a signal along a motor neuron to generate an action potential on the muscle fiber.
