Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The neurons of the ____ system are connected to most of the cells in the muscular system and help to communicate movement.
A
Respiratory
B
Circulatory
C
Digestive
D
Nervous
Explanation: 

Detailed explanation-1: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre. Where they sit together is called a neuromuscular junction.

Detailed explanation-2: -Muscle and nerve communicate at the level of a specialized region, namely the neuromuscular junction (NMJ), a synaptic connection where the peripheral nervous system contacts skeletal muscle fibers, governing crucial vital processes, such as body voluntary movements and breathing [1].

Detailed explanation-3: -Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.

Detailed explanation-4: -Muscles are attached to bones through tendinous tissue and can generate movement around a joint when they contract. The central nervous system controls these movements through the spinal motor neurons, which serve as the final common pathway to the muscles (1).

Detailed explanation-5: -The site where motor neurons and muscle cells communicate with each other is called the neuromuscular junction. This is where the neurons transfer signal substances that can be taken up by the muscle cells to make them contract.
