A neuromuscular junction refers to the chemical synapse between the muscle fiber and the motor neuron.
The neuromuscular junction is the site of communication. It's made up of four cell types which are the <em>muscle fibers, motor neurons, Schwann cells, and motor neurons.</em>
The neuromuscular junction also sends signals from the motor neuron to the skeletal muscles. It is responsible for transmitting <em>action potentials </em>from the motor neurons to muscle contractions.

Catastrophism is associated with major changes that occurs once at a time in a species while gradualism is associated with tiny changes that occurs over a period of time that finally contributes a bigger evolutionary change.
<u>Explanation:</u>
The events that are sudden, short-lived, violent occurring worldwide thereby changing the shape of the Earth is Catastrophic. This process is opposite to contrast to gradualism which is also called as uniformitarianism. This process is associated with slow and also incremental changes. Erosion is the best example for this process.
The formation of major mountain chains and great floods are some of the examples of Catastrophism. Both are associated with the changes that occurs in a species by the time taken for the changes determines whether it is Catastrophism or gradualism.
