Question

Describe the path a signal takes to cross from one neuron to another across a myoneural junction. Place the events in the proper order, and use key vocabulary to describe each structure.

Answer 1

The path a signal takes to cross from one neuron to another, across a myoneural junction can be described in the following way: A myoneural junction is also known as a neuromuscular junction. It is where the nerve and muscle join. A synapse forms between the motor neuron and the muscle fiber. This junction is where the motor neuron is able to send a signal to the muscle fiber, causing the muscle to contract. In practice, the brain sends a signal to the muscle fiber to contract. This signal moves down the neuron and gets to the chemical junction between the neuron and the muscle. The signal jumps over the synapse and hits the muscle. The signal then causes the muscle to move.
