The town in "The Pearl" by John Steinbeck is compared to a nervous system because news and gossip travel rapidly through its inhabitants, just like how impulses travel through a nervous system. It highlights the interconnectedness of the community and how quickly information can spread.
Information travels from the brain to the lower extremities through use of the peripheral nervous system. A signal is sent from the brain through the spinal cord and into muscles of the trunk.
Stimulus travels in the body through the nervous system. When a stimulus is detected by sensory receptors, it triggers electrical impulses that travel along nerve cells to the brain. The brain then processes the information and sends signals to coordinate a response, such as moving a muscle or experiencing a sensation.
Both the nervous system and an electric circuit involve the transmission of information or signals through specialized pathways. In the nervous system, signals travel as electrical impulses along neurons, while in an electric circuit, signals travel as electrical currents through wires or components. Both systems rely on the flow of energy to achieve various functions and responses.
This would be a rare situation, but if germs get into the cerebro-spinal fluid, then they would be able to travel through the spine.
These two systems use different transmitters, which are chemical messengers called hormones in the endocrine system, and neurotransmitters that are followed by electrical impulses in the nervous system. The two paths that these two devices use are also completely different. Hormones travel throughout the body through the blood, while neurons transmit information through the nervous system
Information travels through the nervous system, which consists of a network of specialized cells called neurons. When a stimulus is detected by sensory receptors, neurons transmit signals through electrical impulses and chemical messengers called neurotransmitters. These signals travel along the nerves to the brain or other parts of the body, allowing for communication and coordination of different functions.
The nerves throughout the body receive information and travel through the nerves to the brain. These neural impulses are read by the brain. In which case, the brain "decides" on what to do next.
Electrical impulses in tiny little nerve cells in your skin are sent up all of your nerves, until the electric signal reaches your brain. Then it is translated into the feeling that you get. This all happens before you can blink your eyes.
Earthworms don't have spines, so their nerves don't travel through there.
Nerves, the nervous system most of which travel through the spine at some point.
Information from the same sense organs is conveyed to the central nervous system by specialized sensory neurons, which convert physical stimuli into electrical signals known as action potentials. These action potentials travel along nerve fibers to the central nervous system where they are processed and interpreted.
