Quoted: "The neural pathways that control lower-urinary-tract function are organized as simple on–off switching circuits that maintain a reciprocal relationship between the urinary bladder and the urethral outlet. Storage reflexes are activated during bladder filling and are organized primarily in the spinal cord, whereas voiding is mediated by reflex mechanisms that are organized in the brain (FIG. 5)."

fullness.

What is a spinal nerve?
A spinal nerve which carries motor, sensory, and autonomic signals between the spinal cord and the body.
Spinal nerves are purely sensory and motor?
Spinal nerves are mixed nerves, meaning they contain both sensory and motor fibers. Sensory fibers transmit information from the body to the brain, while motor fibers carry signals from the brain to muscles, glands, and other effector organs. This dual function allows spinal nerves to both receive sensory input and initiate motor output.
How does the spinal column work with the nervous system?
The spinal column serves as the main pathway for the nervous system to transmit messages between the brain and the rest of the body. It protects the spinal cord, which is the main communication highway of the nervous system. Nerves branch out from the spinal cord to different parts of the body, allowing for the relay of sensory information and motor commands.
How does the spinal cord serve as a relay station?
Transmits neural signals between the brain and the rest of the body.
Which part of the human body sends signals to help you move breath and eat etc.?
The nervous system, specifically the brain and spinal cord, is responsible for sending signals to help control movements, breathing, and eating. The brain processes information and sends signals through the spinal cord to different parts of the body to coordinate these functions.
What is the system that carries electrical signals from your brain and spinal cord?
The system that carries electrical signals from your brain and spinal cord is called the nervous system. Specifically, the signals are transmitted through specialized cells called neurons, which make up the communication network of the body.
Is the spinal cord the brain of the brain?
Nope! The spinal cord connects the brain to the rest of the nervous system in the body, sending and receiving signals. It is a conduit, nothing more.
Spinal nerves carry what kind of information?
The spinal cord handles electrical signals sent between the brain and the rest of the body.
Do involuntary responses include the spinal cord and not the brain?
No, the brain reads all signals and controls the entire body. The spinal cord is just a "path" for the neurons to take to get to the brain.
What does the spinal nerve do?
Spinal nerves are pain receptors that carry signals to the brain when pain is felt.
What is controlled by the spinal cord?
The whole body. The spinal cord acts as the transmission system that transmits nervous signals from the brain to the rest of our body. Also, the spinal cord controls numerous nervous reflexes in our body. It is about 45 cm long for men and 43 cm long for women.
What system of body is made of brain the spinal cord and the nerves?
The system of the body is made of the brain spinal cord and nerves is known as the nervous system. The nervous system controls the body's voluntary and involuntary actions and transmits signals between different parts of its body.
