because its lazy!!
The nervous system sends a message to your brain and your brain send a message back "telling you what to do". Sending a message to your brain and your brain sending one back takes a shorter time than it does for you to blink once.
Messages are carried to the brain through neurons, which are specialized cells that transmit information in the form of electrical impulses. These impulses travel along neural pathways and ultimately reach the brain where they are processed and interpreted.

The corticospinal tract, extrapyramidal system, and rubrospinal tract together form the major outgoing motor pathways from the brain to the body. These pathways control voluntary movement and posture by transmitting motor signals from the brain to the spinal cord and ultimately to the muscles.
Yes, the message of pain from a burned finger is transmitted to the brain via nerve signals. Specialized sensory nerve endings in the skin, called nociceptors, detect the heat and tissue damage from the burn, sending signals along nerve fibers to the spinal cord and then onto the brain for processing and perception of pain.

When you want to move a muscle, your brain sends a message out to the muscle you want to move, and the muscle sends a message back to your brain that your moving it and where.
Sensory pathways travel from the body to the brain. They carry information from sensory receptors in the body to the brain where the information is processed and interpreted.

The sensory neurons in your peripheral nervous system are responsible for detecting pain signals from your body and transmitting them to your brain. These neurons are equipped with specialized receptors that respond to stimuli like temperature, pressure, and tissue damage, sending electrical signals along nerve pathways to your brain to signal pain.
You can think of a brain pathway as a power line that connects two brain regions. Brain pathways are made up of interconnected neurons along which signals are transmitted from one brain region to another.

Your afferent neurons send a message to your brain.
Nerves
The small groups of nerves outside the brain are called ganglia. Ganglia are clusters of nerve cell bodies (neurons) that are part of the peripheral nervous system and can be found along nerve pathways.
